back to article AWS puts latest homebrew Graviton3 Arm processor in production

Amazon Web Services has made its latest homebrew processor, the Graviton3, available to rent in its Elastic Compute Cloud (EC2) infrastructure-as-a-service offering. The cloud colossus unveiled Graviton3 at its late-2021 re:Invent conference, revealing that the 55-billion-transistor device includes 64 Arm-compatible CPU cores …

    Take that, you x86 dinosaurs

    We can take that. The Graviton3 is not the comet to end all x86s.

    Don't worry, we'll still be around for a loooong time.

    The lack of benchmarks in this article is deafening.

      At $2.32 to rent 64 vCPUs for an hour a prospective user could try it for themselves and make their own decision based on their workload rather than trusting a benchmark.

        The discount is hardly sufficient to warrant such trials. But, as usual, the CPU is only a small part of the picture: unless you're transcoding video, etc. RAM and IO will be more important.

        And citing Snap as a customer is hardly going to inspire anyone; Snap who?

      Ah. You want facts.

      We live in the post-truth era. Facts are for pussies. It's all about how one feels.

      Why not have a look at usual suspects' site

    The price differential between graviton3 & EPYC is so low, I would not even consider it.

      Former boss of mine had a saying about attractive low pricing.

      "There's a difference between a £5 and a £500 hooker."

      Take the lowest bidder and you can never complain about the quality of the services received.

    I wonder if these Graviton 3 CPUs are more energy efficient than a 64 core x86-64 CPU when fully maxed out?

    As with energy prices going up worldwide due to Ukraine invasion that might be a big reason for more cloud providers to try and push ARM as they cost less leccy to run

      And do they slow down when hot? (As Raspberry Pi do.)

        All chips do this to avoid overheating, which can damage them and also lead to inaccurate calculations in some cases.

      More and more data centres have their own, often renewable, power supply so electricity costs are less important than they used to be.

      The Graviton doesn't have as much oomph as a Xeon or an Epyc so a direct comparison isn't possible. However, data suggests a convergence of power/task across most of the architectures. Arm has some advantages but when you want grunt, you'll need juice. And the prices indicate this much. Arm has an advantage of size, which is why it's the dominant platform on mobile devices.

      The reason for Amazon pushing its own silicon is purely self-serving as the chips are a lot cheaper to buy. Also, as they're smaller, you can cram more of them in a rack.
