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.
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 …
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.
