Amazon Announces Arm Based Graviton3 Processors, Opens up EC2 C7g Preview Instances

As Amazon is continuing to grow its AWS business, both with new instances powered by AMD's third generation of EPYC processors and it's new EC2 C5g instances powered by its current Graviton2 processors and Nvidia's T4G tensor core GPUs. However, the company is also opening up its first EC2 C7g preview instances using its brand new Graviton3 processors, which the company claims offer vastly improved performance over the Graviton2 on specific workloads.

EC2 stands for Elastic Compute Cloud and judging by the fact that the Graviton3 is said to have up to twice as past FPU performance for scientific workloads and being twice as fast for cryptographic workloads and up to three times faster for machine learning workloads, you can guess who these new EC2 instances are intended for. Amazon didn't reveal much in terms of technical details about the Graviton3, but it'll utilize DDR5 memory, which makes it one of the first, if not the first server CPU to use DDR5. It's also said to use up to 60 percent less energy than the Graviton2, while delivering up to 25 percent more compute performance. It's implied that it uses the Arm v9 architecture and the Neoverse N2 Arm cores, although this hasn't been officially announced.

does it really make sense to go with ddr5? unless it's still some time away from reaching the market

That's something you're going to have to ask Amazon, but it's not as if they sell these processors, they're only used by Amazon for their AWS service.
It's possible that they needed the extra memory bandwidth, I really don't know, since the information about all of their Graviton processors are quite limited.
Anandtech did some testing on the Graviton2 last year.
