With both the M5a and M5ad instances using EPYC 7571 processors, the performance in some workloads is similar between these types. In cases like the Leela Chess Zero benchmark, the Intel M5 instances are much faster while the AMD instances did come out ahead of the Arm Graviton instances.

When it came to image resizing with GraphicsMagick, the EPYC instances were comparable to the Intel instances while the Graviton CPU performance saw the a1.4xlarge performance below the x86_64 2xlarge instance types.

The A1 instances though do compete on performance-per-dollar.

Interestingly the Arm A1 instances were competitive with the Intel and AMD instances for the TTSIOD renderer performance.

But when firing off the Primesieve prime number benchmark, the A1 instances were much slower while the AMD instances were a stone's throw behind the Xeon Platinum competition.
