80-Core Ampere Altra Server CPU Competes Well Against Xeon and Epyc

Ampere Altra Performance Shows It Can Compete With - Or Even Outperform - AMD EPYC & Intel Xeon
While the talk in recent weeks has been about the performance of Apple's M1 ARM chip and then rumors there might be a 32 core chip in the pipe, there is already something much stronger: Ampere Altra has begun shipping and its flagship 80-core SoC with up to two sockets per server can easily take on the AMD EPYC 7742 "Rome" and Intel Xeon Platinum 8280 "Cascade Lake" performance across a variety of workloads. Here is our initial look at the Ampere Altra performance on Linux in our independent performance benchmarks.
[...] Prior to receiving the Ampere Altra Mount Jade server and prior to seeing the performance potential with Apple's M1 chip on the desktop side, I figured the Ampere Altra performance would be like that of prior ARM server chips where in best case scenarios may put up a good fight against Intel/AMD but not outright exceed in both raw performance and performance-per-Watt for a variety of workloads. After seeing the results I was very surprised with how well the Ampere Altra Q80-33 2P performance is against the Xeon Platinum 8280 and EPYC 7742 servers. The performance exceeded my expectations where the Ampere Altra was able to collect wins in not only the performance-per-Watt but in the raw performance as well. Aside from software not yet optimized for the AArch64 architecture, the worst case was generally the Ampere Altra coming a bit behind the x86_64 competition but even then it enjoyed much lower power consumption than the x86_64 processors tested.
