64C / 64T 2.5 GHz  vs 80C / 80T 3Ghz

Each of the 80 cores is designed to run at 3.0 GHz all-core
, and Ampere was consistent in its messaging in that the top SKU is designed to run at 3.0 GHz at all times, e
ven when both 128-bit SIMD units per core are being used (thus an unlimited turbo at 3.0 GHz)
. The CPU range will vary from 45W to 210W


Ampere has some performance numbers, which as always we take with a grain of salt.
These include 2.23x the performance on SPEC2017_int rate over a single 28-core Intel Xeon Platinum 8280,
and 1.04x over a single 64-core AMD EPYC 7742.
This is obviously extended into a number of claims about improved TCO. Ampere didn’t provide similar numbers for SPEC2017_fp,
because the company states that the SoC has been developed with INT workloads in mind
