Amazon Graviton3 vs Intel Xeon vs AMD EPYC Performance Review

Earlier this week, AWS announced the general availability of its new Arm Neoverse V1-based Graviton3 processors. Right after that I posted some initial Graviton3 benchmarks against the previous generation Graviton2 to show the very significant generational improvement with Amazon’s new in-house Arm server processors. Since then I’ve run a more robust set of around 100 benchmarks across the original Graviton instance, Graviton2, Graviton3, and then again across competing Intel Xeon and AMD EPYC instances. Here is the much larger collection of Graviton3 performance benchmarks run on Ubuntu 22.04 LTS.

For today’s article, the following Amazon EC2 instances were benchmarked to better assess the performance potential of Graviton3 and also the price-performance ratio in Amazon’s cloud:

a1.4xlarge – The original Graviton processors with Cortex-A72 cores. The a1.4xlarge instance type cost $0.408 per hour on demand.

c6g.4xbig – Graviton2 of the now previous generation…
