SPEC workloads are only meaningful if submitted to SPEC.org [ … ]. MySQL multiple index columns have a full cardinality? And even if the threads are ignored and a virtual machine is allocated to a core, AMD Epycs top out at 64 cores, or a 50 percent advantage to Marvell, and Intel really – for all practical purposes – tops out at 28 cores or a 3.4X advantage. x86 vs ARM: Leakage Current Leakage current became a significant contributor to power consumption in 2003 with the move from 0.18 to 0.13 micron feature sizes, and has become more significant in each subsequent generation. The AMD Epyc 7702 server has a similar configuration, and the two Intel machines assume twelve memory sticks because they only have six memory controllers per socket. So I’m interested not only in the CPU processor side but also the software/firmware and Motherboard platform ecosystem side as CPUs alone are just one part of the TCO. You cited one of the significant contributors to performance - the 8-wide decode. Absent that, this is nothing more than marketing in disguise. Because SPEC requires a supported compiler that can be downloaded and used by anyone. x86 can afford to go low because it can recover its NRE costs in other markets (desktop, laptop). And while the Arm server chip upstarts, Ampere Computing and Marvell, were not planning for a global pandemic when they timed the launches of their chips on their roadmaps, they may be among the beneficiaries of the budget tightening that will no doubt start at most companies – if it hasn’t already. I expect that it can produce a 100-150W part that is higher perf and per/watt than its comparable x86 competition and that is where the real draw of the ARM many-core design can be. Xeon (x86) Cascade Lakes has been just good enough to keep business, data processing, production operations and communications up and running, this generation of infrastructure, on Intel’s ability to supply incumbent use concerned with keeping product market and financial share and the business humming along. x86 has two big licensees, Intel and AMD, and VIA has no real presence. entirely possible that you can get pretty significant power savings, How digital identity protects your software, Podcast 297: All Time Highs: Talking crypto with Li Ouyang. This chart talks about watts per core comparisons of the same processors: The cores are less oomphie in the Ampere Altra chips than in the Epyc or Xeon SP processors, so it is no surprise that the watts per core is lower. No one is suggesting that anyone buy machines based on vendor competitor analysis, which would be utterly stupid. It would have been useful if Marvell had provided absolute rather than relative performance here. Business will hum along, choice returns, industry and society will be better for it. Are popular benchmarks valid comparisons of architectures? This is aimed mostly at companies who own their own application stack, and often the system stack, and thus, that point is moot. The reality was, and is, that 1T performance is paramount, SMT is gravy on top. What is the performance per watt for Graviton vs Intel? More significantly, this table suggests ARM and MIPS have 40% - 50% better energy per MHz and their size is a factor of 3X to 4X smaller than x86. Capital gains tax when proceeds were immediately used for another investment, Short story about creature(s) on a spaceship that remain invisible by moving only during saccades/eye movements. Long story short: People say the move from intel x86 to arm is monumental and a huge technical breakthrough. There seems to be some weird notion amongst certain corners of the internet (and I can suspect the origin of these) that SPEC workloads are only meaningful if submitted to SPEC.org, when that’s a fairly silly notion. for example https://s.dou.ua/storage-files/1_SPECrate2017_int_Fixed.PNG. But what the tests are really comparing? x86 is hamstrung to 4 because of legacy. And the OS/Software and firmware ecosystem plays an even greater role in making any server hardware offering successful, and that includes OEM Partner support as well. That brings us to the last chart in the deck from Ampere Computing, which shows the performance per total cost of ownership deltas between the four chips shown below: This is a system level comparison and the rack of servers using the Altra processors are using a pair of those 180 watt parts (which we estimated some feeds and speeds for) plus sixteen 16 GB memory sticks (256 GB of memory), a pair of Ethernet NICs, a 1 TB SATA drive, and base components like baseboard management controllers, power supplies, and such. As we said in the article, this is a baseline performance run with standard flags, and we think it is not only absolutely valuable to have this consistent compiler substrate running across generations and architectures, we also think people have a very good sense that for a lot of workloads, the ICC compiler delivers somewhere around 20 percent more performance on a wide range of workloads. What is annoying about what Ampere Computing has done in the following charts is that it is comparing different AMD Epycs and different Intel Xeon SPs with its Altra, and in some cases – as with the cost per total cost of ownership of a rack-scale cluster of servers – it is using a lower-bin Altra part in that comparison. Mobile ARM processors for heavy 3d tasks? And what will become of Samsung’s discontinued Mongoose development as well as AMD’s mothballed Project K12(Custom server core IP). This gets us started on the process of thinking about how these different chips might stack up to each other. As you can see from the numbers on that article - Atom processors designed for mobile devices already match ARM processors on the power efficiency front - so its probably worth wondering why they arn't more common.

Then again, implementing this translation layer requires additional silicon space on the chip... That said, assuming that they are implemented using the same semiconductor process, is ARM inherently more efficient than x86? The seesaw mobile processor battle between ARM and Intel continued at Computex, with ARM claiming it offered better performance per watt for mobile devices than Intel's upcoming chips.

Take a gander: Now let’s get down to the X86 comparisons. Comparing performance per megahertz, x86 is 4% - 8% faster than ARM or MIPS. How to lock a shapefile in QGIS so only I can edit. Overall on paper Falkor looks very competitive. Super User is a question and answer site for computer enthusiasts and power users. Something as simple as avoiding inefficient power conversions can do a fair bit. Do studs in wooden buildings eventually get replaced as they lose their structural capacity? At this time beginning now and into the next 60 months, the total available market for processors of all types supporting existing infrastructure and build out exceed 1.5 trillion units of Xeon in use. The first thing we figured out is that it looks like the top-bin Altra part will burn 205 watts, not 200 watts flat, because that is the only way the numbers that are shown in the chart below work out: Assuming that it is keeping the 80-core part in the comparison but using a slower 180 watt part, which is mentioned in the notes on these charts, you will note that it has shifted to the AMD Epyc 7702 for the comparison above, which has 64 cores running at 11 percent lower clock speed and which also, at 200 watts, burns 11 percent less juice than the 225 watt Epyc 7742 shown in the first chart. For companies that need to design their own processors, or to tweak it, this means significant savings in R&D without needing to develop everything from scratch (tricky) or to buy processors from another company (with x86, we have Via, AMD and Intel, but only intel seem really interested in the mobile space, and I have no clue what via is up to). The SPEC integer benchmark result is here for a Dell PowerEdge MX740c based on a pair of these CPUs. I thought I'd do a head-to-head comparison with some hardware I already have. Compared to Intel processor, ARM CPU also supports technologies such as Neural Engine to make ARM Mac a good choice for machine learning. There are extremely well known reasons why people choose not to compare directly to results from SPEC.org, because the specialized compilers that are rolled out for those results have coded tricks built into the compiler themselves to target individual SPEC benchmarks. AWS introduced Graviton2 at Re:invent 2019 and is based on ARM Neoverse N1 cores, which scale from 8 to 16 cores per chip and 128 cores per socket in server architectures. In its tests, Marvell is looking at the SPECrate 2017 Integer Peak performance of the chips. Let’s look at whole market; client base station, cell network, network edge, metro edge, data center processing, aggregation, switch and route; public, private, enterprise, government communications, telecommunications, packet processing and inspection, security, switch and route, long haul carrier network and control; rural, suburban, urban spoke and hubs, network computing, HPC and supercomputing. At roughly a quarter the performance of world-leading x86 and ARM mobile processors, the Micro Magic CPU doesn't sound like much yet. reply. Bet you get voted most edgy cool dood on earth! So that gives that two-socket machine an estimated rating of 557 and therefore each Epyc 7742 processor a rating of 278.5. THe real question is how low can an ARM supplier go while having some margin? Companies: #arm #intel #tsmc. In theory a Falkor core can process 8 instructions/cycle, same as Skylake or Broadwell, and it has higher base frequency at a lower TDP rating. And the whole point of these SPEC requirements is that the claimed results must be repeatable and reproducible by anyone. So is price, and we can’t really do a full analysis of Arm server chips compared to X86 until the products actually roll out and we see the prices, too. In this article we are just looking at the raw performance for these x86_64/ARM/POWER9 servers using various tests that operate well cross-architecture. It really seems like ARM is inherently more power-efficient than x86. Why everyone suddenly thinks ARM will dominate x86? (Ampere Computing and Marvell are giving some hints on price/performance, which we can work backwards to get an initial price for at least a few SKU in their respective lineups. This machine had a base SPEC integer rating of 342, which after a conversion to estimated GCC results by multiplying by 76 percent yields 260 and that works out to 130. Good performance in x86 requires extensive branch prediction hardware, where ARM is served with a far simpler implementation. In this way, you can see the full spectrum of platforms and tunings and how it might be correlated in the past and in the future with actual applications. Going back to the data we see that the best ARM core, the custom Apple A13 Lightning is about as high performance as the best x86 core, in this case the Intel Ice Lake i7-1068NG7. And now we are going to go through the performance and price/performance competitive analysis that these two chip makers have done as they talk about their impending server chips. I’m less interested in benchmarks from any processor makers as the fine arts of compiler flags setting and cherry-picking of benchmarks is well developed. Now here is some insight into how Marvell thinks the top-bin ThunderX3 will stack up against the AMD Epyc 7742 and Intel Xeon SP 8280 on HPC workloads: Because of the expected higher clock speed of its four SIMD units, Marvell is going to have a raw floating point advantage over the Cascade Lake Xeon SPs and Rome Epycs, according to the company. Would like to see performance comparison of graviton2 vs altra vs thunder x3, the real situation is completely different So, our attitude is that all CPUs should run the standard tests on GCC since it is supported equally well (or poorly depending on how you want to look at it) on all CPUs, and then each vendor should trot out their optimized compilers to show the uplift they get on these microbenchmarks and other systems level software such as databases and then the actual workloads should be tested. It’d be better if they just ran benchmarks with the same neutral non-cheating compilers with the same flags on both their chip and whichever competitors they are comparing with. There are rules for submitting SPEC benchmark results that are designed to minimize hype, marketing and flat-out lies. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Cavium has no real volume worth speaking of, so the top-bin parts will be in short supply or expensive to produce (yields).

Let’s look at whole market; client base station, cell network, network edge, metro edge, data center processing, aggregation, switch and route; public, private, enterprise, government communications, telecommunications, packet processing and inspection, security, switch and route, long haul carrier network and control; rural, suburban, urban spoke and hubs, network computing, HPC and supercomputing. At roughly a quarter the performance of world-leading x86 and ARM mobile processors, the Micro Magic CPU doesn't sound like much yet. reply. Bet you get voted most edgy cool dood on earth! So that gives that two-socket machine an estimated rating of 557 and therefore each Epyc 7742 processor a rating of 278.5. THe real question is how low can an ARM supplier go while having some margin? Companies: #arm #intel #tsmc. In theory a Falkor core can process 8 instructions/cycle, same as Skylake or Broadwell, and it has higher base frequency at a lower TDP rating. And the whole point of these SPEC requirements is that the claimed results must be repeatable and reproducible by anyone. So is price, and we can’t really do a full analysis of Arm server chips compared to X86 until the products actually roll out and we see the prices, too. In this article we are just looking at the raw performance for these x86_64/ARM/POWER9 servers using various tests that operate well cross-architecture. It really seems like ARM is inherently more power-efficient than x86. Why everyone suddenly thinks ARM will dominate x86? (Ampere Computing and Marvell are giving some hints on price/performance, which we can work backwards to get an initial price for at least a few SKU in their respective lineups. This machine had a base SPEC integer rating of 342, which after a conversion to estimated GCC results by multiplying by 76 percent yields 260 and that works out to 130. Good performance in x86 requires extensive branch prediction hardware, where ARM is served with a far simpler implementation. In this way, you can see the full spectrum of platforms and tunings and how it might be correlated in the past and in the future with actual applications. Going back to the data we see that the best ARM core, the custom Apple A13 Lightning is about as high performance as the best x86 core, in this case the Intel Ice Lake i7-1068NG7. And now we are going to go through the performance and price/performance competitive analysis that these two chip makers have done as they talk about their impending server chips. I’m less interested in benchmarks from any processor makers as the fine arts of compiler flags setting and cherry-picking of benchmarks is well developed. Now here is some insight into how Marvell thinks the top-bin ThunderX3 will stack up against the AMD Epyc 7742 and Intel Xeon SP 8280 on HPC workloads: Because of the expected higher clock speed of its four SIMD units, Marvell is going to have a raw floating point advantage over the Cascade Lake Xeon SPs and Rome Epycs, according to the company. Would like to see performance comparison of graviton2 vs altra vs thunder x3, the real situation is completely different So, our attitude is that all CPUs should run the standard tests on GCC since it is supported equally well (or poorly depending on how you want to look at it) on all CPUs, and then each vendor should trot out their optimized compilers to show the uplift they get on these microbenchmarks and other systems level software such as databases and then the actual workloads should be tested. It’d be better if they just ran benchmarks with the same neutral non-cheating compilers with the same flags on both their chip and whichever competitors they are comparing with.

arm vs x86 performance per watt

23 de dezembro de 2020 | por

x86-64 Assembly - Sum of multiples of 3 or 5. What makes ARM "better" than x86 really has more to do with market forces than raw performance. To get a number of the Intel Xeon SP, Ampere Computing chose the Dell PowerEdge R740xd that was tested back in March 2019 using a pair of 28-core “Cascade Lake” Xeon SP 8280 Platinum chips, which run at 2.7 GHz. What did I leave out? It is not directly related to x86 vs arm. How to identify whether a TRP Spyre mechanical disc brake is the post-recall version? Featuring highlights, analysis, and stories from the week directly from us to your inbox with nothing in between. Why is this gcd implementation from the 80s so complicated? In what way would invoking martial law help Trump overturn the election? Based on all of these different SKUs and data points, here is a summary table that adds it all together, including the GCC performance estimates: Based on the idea that Ampere Computing has to offer at least a 20 percent price/performance advantage at the chip level compared to the best that Intel and AMD can throw at the cost per performance per watt equation that dominates the buying decisions of the hyperscalers and cloud builders that Ampere Computing is targeting. > SPEC workloads are only meaningful if submitted to SPEC.org [ … ]. MySQL multiple index columns have a full cardinality? And even if the threads are ignored and a virtual machine is allocated to a core, AMD Epycs top out at 64 cores, or a 50 percent advantage to Marvell, and Intel really – for all practical purposes – tops out at 28 cores or a 3.4X advantage. x86 vs ARM: Leakage Current Leakage current became a significant contributor to power consumption in 2003 with the move from 0.18 to 0.13 micron feature sizes, and has become more significant in each subsequent generation. The AMD Epyc 7702 server has a similar configuration, and the two Intel machines assume twelve memory sticks because they only have six memory controllers per socket. So I’m interested not only in the CPU processor side but also the software/firmware and Motherboard platform ecosystem side as CPUs alone are just one part of the TCO. You cited one of the significant contributors to performance - the 8-wide decode. Absent that, this is nothing more than marketing in disguise. Because SPEC requires a supported compiler that can be downloaded and used by anyone. x86 can afford to go low because it can recover its NRE costs in other markets (desktop, laptop). And while the Arm server chip upstarts, Ampere Computing and Marvell, were not planning for a global pandemic when they timed the launches of their chips on their roadmaps, they may be among the beneficiaries of the budget tightening that will no doubt start at most companies – if it hasn’t already. I expect that it can produce a 100-150W part that is higher perf and per/watt than its comparable x86 competition and that is where the real draw of the ARM many-core design can be. Xeon (x86) Cascade Lakes has been just good enough to keep business, data processing, production operations and communications up and running, this generation of infrastructure, on Intel’s ability to supply incumbent use concerned with keeping product market and financial share and the business humming along. x86 has two big licensees, Intel and AMD, and VIA has no real presence. entirely possible that you can get pretty significant power savings, How digital identity protects your software, Podcast 297: All Time Highs: Talking crypto with Li Ouyang. This chart talks about watts per core comparisons of the same processors: The cores are less oomphie in the Ampere Altra chips than in the Epyc or Xeon SP processors, so it is no surprise that the watts per core is lower. No one is suggesting that anyone buy machines based on vendor competitor analysis, which would be utterly stupid. It would have been useful if Marvell had provided absolute rather than relative performance here. Business will hum along, choice returns, industry and society will be better for it. Are popular benchmarks valid comparisons of architectures? This is aimed mostly at companies who own their own application stack, and often the system stack, and thus, that point is moot. The reality was, and is, that 1T performance is paramount, SMT is gravy on top. What is the performance per watt for Graviton vs Intel? More significantly, this table suggests ARM and MIPS have 40% - 50% better energy per MHz and their size is a factor of 3X to 4X smaller than x86. Capital gains tax when proceeds were immediately used for another investment, Short story about creature(s) on a spaceship that remain invisible by moving only during saccades/eye movements. Long story short: People say the move from intel x86 to arm is monumental and a huge technical breakthrough. There seems to be some weird notion amongst certain corners of the internet (and I can suspect the origin of these) that SPEC workloads are only meaningful if submitted to SPEC.org, when that’s a fairly silly notion. for example https://s.dou.ua/storage-files/1_SPECrate2017_int_Fixed.PNG. But what the tests are really comparing? x86 is hamstrung to 4 because of legacy. And the OS/Software and firmware ecosystem plays an even greater role in making any server hardware offering successful, and that includes OEM Partner support as well. That brings us to the last chart in the deck from Ampere Computing, which shows the performance per total cost of ownership deltas between the four chips shown below: This is a system level comparison and the rack of servers using the Altra processors are using a pair of those 180 watt parts (which we estimated some feeds and speeds for) plus sixteen 16 GB memory sticks (256 GB of memory), a pair of Ethernet NICs, a 1 TB SATA drive, and base components like baseboard management controllers, power supplies, and such. As we said in the article, this is a baseline performance run with standard flags, and we think it is not only absolutely valuable to have this consistent compiler substrate running across generations and architectures, we also think people have a very good sense that for a lot of workloads, the ICC compiler delivers somewhere around 20 percent more performance on a wide range of workloads. What is annoying about what Ampere Computing has done in the following charts is that it is comparing different AMD Epycs and different Intel Xeon SPs with its Altra, and in some cases – as with the cost per total cost of ownership of a rack-scale cluster of servers – it is using a lower-bin Altra part in that comparison. Mobile ARM processors for heavy 3d tasks? And what will become of Samsung’s discontinued Mongoose development as well as AMD’s mothballed Project K12(Custom server core IP). This gets us started on the process of thinking about how these different chips might stack up to each other. As you can see from the numbers on that article - Atom processors designed for mobile devices already match ARM processors on the power efficiency front - so its probably worth wondering why they arn't more common.

Intel, on the other hand, consumes a lot more power, to get a lot more work gone at larger form-factors. Take a look at the whole market; client base station, cell network, network edge, metro edge, data center processing, aggregation, switch and route; public, private, enterprise, government communications, telecommunications, packet processing and inspection, security, switch and route, long haul carrier network and control; rural, suburban, urban spoke and hubs, network computing, HPC and supercomputing. Then again, implementing this translation layer requires additional silicon space on the chip... That said, assuming that they are implemented using the same semiconductor process, is ARM inherently more efficient than x86? The seesaw mobile processor battle between ARM and Intel continued at Computex, with ARM claiming it offered better performance per watt for mobile devices than Intel's upcoming chips. The gap between the performance of processors, broadly defined, and the performance of DRAM main memory, also broadly defined, has been an issue for at […], If you are going to take on Intel in server processors, you have to play the same kind of long game that Intel itself played […], The GPU has become a standard platform for accelerating high performance computing workloads, at least for those that have had their code tweaked to support […]. In relation to current level of network performance which is key to data center growth, network always comes first, as PAM 4 rolls out over the top, switch throughput in the middle, 5G from the edge existing compute infrastructure will be displaced quickly on new network communications and standards (programmable) and hard data processing replacements, light and heavy loads, specialties acceleration, better and best fit for use. Take a gander: Now let’s get down to the X86 comparisons. Comparing performance per megahertz, x86 is 4% - 8% faster than ARM or MIPS. How to lock a shapefile in QGIS so only I can edit. Overall on paper Falkor looks very competitive. Super User is a question and answer site for computer enthusiasts and power users. Something as simple as avoiding inefficient power conversions can do a fair bit. Do studs in wooden buildings eventually get replaced as they lose their structural capacity? At this time beginning now and into the next 60 months, the total available market for processors of all types supporting existing infrastructure and build out exceed 1.5 trillion units of Xeon in use. The first thing we figured out is that it looks like the top-bin Altra part will burn 205 watts, not 200 watts flat, because that is the only way the numbers that are shown in the chart below work out: Assuming that it is keeping the 80-core part in the comparison but using a slower 180 watt part, which is mentioned in the notes on these charts, you will note that it has shifted to the AMD Epyc 7702 for the comparison above, which has 64 cores running at 11 percent lower clock speed and which also, at 200 watts, burns 11 percent less juice than the 225 watt Epyc 7742 shown in the first chart. For companies that need to design their own processors, or to tweak it, this means significant savings in R&D without needing to develop everything from scratch (tricky) or to buy processors from another company (with x86, we have Via, AMD and Intel, but only intel seem really interested in the mobile space, and I have no clue what via is up to). The SPEC integer benchmark result is here for a Dell PowerEdge MX740c based on a pair of these CPUs. I thought I'd do a head-to-head comparison with some hardware I already have. Compared to Intel processor, ARM CPU also supports technologies such as Neural Engine to make ARM Mac a good choice for machine learning. There are extremely well known reasons why people choose not to compare directly to results from SPEC.org, because the specialized compilers that are rolled out for those results have coded tricks built into the compiler themselves to target individual SPEC benchmarks. AWS introduced Graviton2 at Re:invent 2019 and is based on ARM Neoverse N1 cores, which scale from 8 to 16 cores per chip and 128 cores per socket in server architectures.

So that gives that two-socket machine an estimated rating of 557 and therefore each Epyc 7742 processor a rating of 278.5. THe real question is how low can an ARM supplier go while having some margin? Companies: #arm #intel #tsmc.
