Amazon Web Services announced new instances for EC2 in the form of the C7g.
Announced at the company’s AWS re: Invent event, the new instances will be powered by its all-new processor, the Graviton3, which targets what AWS calls compute-intensive workloads: HPC, batch processing, electronic design automation (EDA), media encoding, scientific modeling, ad serving, distributed analysis, and processor-based machine learning inference.
So don’t expect them to appear in traditional web hosting environments, although they can be used for bare metal hosting or in dedicated server / VPS type scenarios.
Graviton2 was announced in december 2019 and only launched in June of last year while the original Arm-based Graviton was shown at re: Invent 2018.

Graviton3: What do we know?
Well, AWS claims the new edition is 25% faster than the Graviton2, with 2x floating point performance and 3x improvements in machine learning workloads. Power consumption will be 60% lower – although not much is known about the exact settings.
They will run on DDR5 memory which should offer a 50% increase in memory bandwidth. We don’t know the number of cores, the architecture used, or the core clock speed.
Graviton2 doubled the number of cores of the original 2018 model to 64 cores and used the ARM Neoverse N1 architecture, a 7nm manufacturing process, which took it to 2.5 GHz.
Graviton3 will face new competition from AMD and Intel. The former is expected to introduce its Zen 4 products in 2022 with processors using up to 128 cores on a 5nm process. Intel has already unveiled its “Sapphire Rapids” Xeon processors which bring DDR5 and PCIe 5.0 to the table.
