Of course, the benchmarks in this article are only a subset of the 143 ran in total on Graviton2 vs. EPYC 7742. Above are the highlights. See all 143 benchmarks over on OpenBenchmarking.org.

Of the 143 benchmarks ran, the Amazon Graviton2 m6g.metal came in first place about 9% of the time.

When taking the geometric mean of all these benchmarks, the EPYC 7742 without SMT enabled was about 46% faster than the Graviton2 bare metal performance. The EPYC 7742 with SMT (128 threads) increased the lead to about 51%, due to not all of the benchmarks being multi-thread focused. Graviton2 is a heck of a lot more capable than the original Graviton processor, but still not to the level of competing with AMD EPYC 7002 series across the board. Though for those interested in running Graviton2 in the cloud, as shown in the prior Graviton2 benchmarks, Amazon does offer these 64-bit Arm instances at considerable value and are able to offer competitive performance-per-dollar thanks to those instances being backed always by a physical core for each vCPU rather than a core/SMT combination for the similarly sized Intel Xeon and AMD EPYC instances. Again, those wanting to dig through more data can find it over on OpenBenchmarking.org and you can fire up your own tests with the Phoronix Test Suite.
