There is very little offering and honestly afaik they are not competing on performance except niche applications.

It's not that easy to displace x86...

I'm not sure that is accurate for Gravaton3, which appears to be besting intel/amd in a number of cases. So, it doesn't appear there is a clear leader between the amd, intel and gravaton instances. Meaning everyone should be benchmarking their application and picking one.

Amazon here seems to be leading the Arm technology pack, as they are using a newer generation of CPU, while arm instances on other providers tend to be providing gravaton2 (Neoverse-N1) based instances. I would imagine that gradually changing in the near future as those vendors also upgrade.

Graviton3 on AWS is better for most applications on a cost/performance basis, and in some cases also on straight latency.

Honeycomb has some great blogs about it: https://www.honeycomb.io/blog/present-future-arm-aws-gravito...

I stand corrected ! Note that is on cost/performance, not raw performance yet. Impressive.

And on raw performance: https://www.phoronix.com/scan.php?page=article&item=graviton... (direct link to the geometric mean performance of the whole test suite)

ARM isn't the optimal solution for every application at this time, but anyone who isn't seriously considering it probably needs to update their information.

The big savings on graviton come from no hyperthreading. A VCPU on x86 is a hypercore, but a VCPU on graviton is a full core. So you get a full core and its L1 and L2 all to yourself. Usually for cheaper than an x86 VCPU.

As far as I know most AWS services can be run on graviton instances.
