    Phoronix: AWS Graviton4 vs. AmpereOne 192-Core Benchmarks For Leading AArch64 Server Performance

    With the Supermicro ARS-211M-NR R13SPD server that's in the lab for a few weeks for reviewing the AmpereOne A192-32X and delivering the first independent benchmarks of the AmpereOne 192-core AArch64 server processor, the AmpereOne benchmarks to date have been comparing to other Intel Xeon and AMD EPYC server platforms. But if looking up to the cloud is the closest AArch64 server competition to AmpereOne there is: Amazon's Graviton4. In today's article ia showdown looking at how AmpereOne and AWS Graviton4 compete at 192 cores for ARM 64-bit server performance.

    I don't know a thing about the Graviton CPUs, but maybe if you rented 2 entire CPUs, you end up having 12 x 2 = 24 RAM channels because the CPUs can be in different MBs?

      There has been little news of anyone using the announced-but-not-available Neoverse V3 CPUs sans the little-known Socionext designing a 32C Neoverse V3 chiplet. On a uArch, per-core basis, V3 is a little better than Graviton4's V2.

      V1 → V2 (Sept 2022) yields +13% IPC (SPECint2017)
      V2 → V3 (Feb 2024) yields +12% "integer perf uplift" (unknown)

        Thanks, great article! One remaining questions is how Graviton4 compares to NVIDIA Grace Superchip.

          Why would you buy those CPU servers? Are thy cheaper or better in some use scenarios?

            I wish I could get my hands one an Ampere workstation and build a dual boot Win 11 / Linux system:

            This repo contains scripts and documents to create Windows 11 ISO and install Windows 11 on Ampere CPU based workstation. - AmpereComputing/Windows-11-On-Ampere


            Of course the much cheaper way would be to buy a Qualcomm based system but I would love to have an Ampere.

            Even better, if the Graviton4 was available for a DIY home system, that would be something.

              Thank's to Michael for the Graviton 4 and (at long last) AmpereOne coverage. Today's article would have been shocking if we hadn't already had a fairly clear picture of AmpereOne's disappointing performance.

              AmpereOne has been missing in action for ~ 1.5 years, so it's already at least a generation (or two) behind of eg Graviton 4 and other competitors.

              Still, there may be room for AmpereOne (or hypothesizing: AmpereTwo)​ somewhere and I won't discount the possibility that Ampere's next spin will be vastly better. After all, I surmised that lacklustre performance, quite possibly due to design issues might be the reason why we hadn't seen hair or hide of it. Now it's in the open ... and ... In the meantime we've seen rumors of AmperOne A and AmperOne B as if they might be actual existing products.

              So I ask myself, why did they after all this time show it? Hopefully it's because they have what they actually aimed for nearly ready for launch. I'm not holding my breath, but wish Ampere and us all the best, the best being a highly performant CPU.

                The comparison is 2-P Graviton 4 with 24 DDR channels vs AmpereOne with just 8 DDR channels. So on anything that requires memory bandwidth, Graviton will be 3-4x faster - as the HPC benchmarks show. Coremark and m-queens are very close, being compute intensive.

                A far more interesting comparison would be to compare with 96 core Graviton 4. These have similar per hour costs too. Think of AmpereOne as having twice as many threads with lower performance per thread (like hyperthreading but without all the disadvantages).
