If only dedicated game servers could run on aarch64...

I've been experimenting FEX on Ampere A1 with x86 game servers but the performance is not that impressed

So these are aarch64, right?

    More specifically, the CPU cores in AWS Graviton5 are Neoverse V3 cores, which implement the Armv9.2-A ISA specification.

    Neoverse V3 is the server version of the Cortex-X4 core which has been used in a large number of smartphones.

    The Neoverse V3 and Cortex-X4 cores are very similar in size and performance with the Intel E-cores Skymont and Darkmont (the E-cores of Arrow Lake and of the future Panther Lake).

    Intel will launch next year a server CPU with Darkmont cores (Clearwater Forest), which will have cores similar to this AWS Graviton5, but for now Intel only has the Sierra Forest server CPUs with E-cores (belonging to the Xeon 6 series), which use much weaker CPU cores than those of the new Graviton5 (i.e. cores equivalent with the Crestmont E-cores of the old Meteor Lake).

    AMD Zen 5 CPUs are significantly better for computationally-intensive workloads, but for general-purpose applications without great computational demands the cores of Graviton5 and also Intel Skymont/Darkmont have greater performance per die area and power consumption, therefore lower cost.

      Do you have any insight on when these will be generally available?

        Amazon says "Sign up for the preview today".

        I have no connection with them, so I have no idea when these instances will be generally available.

        Privileged big customers appear to be already testing them.

    Yes, Graviton chips are aarch64.
