AmpereOne A192-32X Benchmarks: 192 Core ARM Server Performance & Power Efficiency

Citiraj:

AmpereOne reviewer system is based on a Supermicro ARS-211M-NR R13SPD that is an air-cooled 2U server solution for AmpereOne processors -- capable of handling up to the top-end 400 Watt processors. The Supermicro ARS-211M-NR R13SPD can handle up to four double-width GPUs, 16 DIMM slots in total for up to 2TB of DDR5-5200 memory with one DIMM per channel or up to 4TB of RAM at two DIMMs per channel but reduced then to DDR5-4400 speeds. The AmpereOne server can boot standard AArch64 Linux distributions like Ubuntu 24.04 LTS and Fedora Server 40. For the initial benchmarking I was using Ubuntu 24.04 LTS. This review server shipped with 8 x 64GB DDR5-5200 DIMMs, Samsung NVMe MZQL23T8HCLS-00A07 + MZ1L2960HCJR-00A07 storage, and using the top-end AmpereOne A192-32X processor. The AmpereOne A192-32X boasts 192 AmpereOne cores, a 3.2GHz clock frequency, a rated 276 Watt usage power, and carries a $5,555 USD suggested price.

The AmpereOne A192-32X performed admirably in matching the performance of a dual Intel Xeon 6766E Sierra Forest configuration overall but behind the Xeon 6780E 2P configuration. The AmpereOne A192-32X in a single socket configuration was also behind the single EPYC 9654 Genoa / 9754 Bergamo / 9684X Genoa-X processors. Going from the Ampere Altra Max M128-30 to AmpereOne A192-32X was 1.56x the performance overall. That's with 1.5x the core count in going from Ampere Altra Max 128 cores to 192 cores with the current top-end AmpereOne SKUs. As shown in the few single-threaded and lightly threaded workloads, there wasn't too much IPC uplift going to AmpereOne from Ampere Altra cores. With AmpereOne is also the move to DDR5 memory from DDR4 and other improvements.

When looking at the CPU power consumption over the span of all the benchmarks carried out, the AmpereOne A192-32X on average was consuming 230 Watts with a peak of 401 Watts, up from a 166 Watt average for the Ampere Altra Max M128-30 with a 166 Watt average and 252 Watt peak. The most significant difference with AmpereOne was unfortunately the much higher CPU power consumption at idle and lightly threaded scenarios. The AmpereOne A192-32X never consumed less than 101 Watts even in the brief periods of being idle... Meanwhile the single Intel / AMD server processors could idle in the 10~20'ish Watt range. The Ampere Altra Max M128-30 could sip as little as 21 Watts. But the AmpereOne didn't drop below 100 Watts. The EPYC 9754 Bergamo had a similar power consumption overall to the AmpereOne A192-32X with a 225 Watt average and 397 Watt peak. The EPYC 9754 would consume just 10 Watts at idle.

Overall this was a better than expected first look at AmpereOne. It's great finally seeing AmpereOne hands-on and the performance being competitive. If AmpereOne had ramped up last year well before Intel Sierra Forest it would have looked extremely compelling with its 192 core part and launching to a very different landscape. Now it's appearing with Intel Sierra Forest having been "launched" since earlier this summer, Intel Granite Rapids coming up soon, and AMD EPYC Turin also due out in the coming months. It will be interesting to see if Ampere Computing can achieve robust availability on AmpereOne processors and platforms before Granite Rapids and EPYC Turin. Hopefully firmware updates can also help with AmpereOne reducing its idle CPU power usage.
