    Not really surprising. After the Meltdown and Spectre issues from Intel CPUs; Amazon and everyone else is hedging their systems so they are not fully reliant on just one supplier.

    If one performs better and/or offers better security/reliability they can use more of them. Easier to switch if you are familiar with more options.

    I actually recently was switched to a new server with my hosting company Linode, and I'm on EPYC processors on the new server. Though you don't typically get to choose what type of system you're on with them.

    The sizing of the m5a & r5a instances doesn't make any sense. With 384 and 768GB of RAM respectively that means they are mixing DIMM sizes based on CPU sockets. Would have made more sense to have them be 512 & 1024GB, as well as 128 vCPUs but that is different issue.

    768 / 96 processors... looks fine to me

    1024/96 would have made more sense with the 8 channels of RAM per socket. 768 would be 8x64 + 8x32 instead of 1024 which is 16x64

    What they allocate to you, doesn't necessary tell you anything about the underlying HW.

    Maybe they have a mixture of different hw and want to limit the maximum vm size to something that can fit comfortably to all different kind of HW configs.

    Or maybe they don't want to sell you 1:1 virtualization in these pricing bracket and rather have that as a separate product -> you can never buy whole host.
