Amazon just released the second generation of independently designed server chip“Graviton2”It can be called the strongest arm platform processor so far, and it is no inferior to Intel's top platinum.

Amazon graviton 2 adopts arm's latest neoverse N1 CPU architecture, which is built by its own design team, and directly stacks to 64 cores, which is four times of the first generation (twice as much as previously reported). Moreover, it uses top-level configuration. Each core has 1MB level-2 cache, with a total of 64MB. All cores share 32MB level-3 cache.

64 cores are interconnected by mesh fabric, and the combined bandwidth is as high as2TB/s。 SupportEight channel ddr4-3200 memory, support hardware AES-256 memory encryption, support64 PCIe 4.0


Officially,Graviton2 has up to seven times the performance of the first generation and up to five times the memory access speed.

At the same time, Amazon also launched a series of sixth generation instances based on graviton 2, including M6G, R6G and c6g, with different configurations and up to 256gb of memory.

Amazon also compared it to a fifth-generation example with Intel to strong platinum (highest 3.1GHz), with a single-core performance lead: SPECjvm 2008 43 per cent (estimated), SPEC CPU 2017 integer 44 per cent (estimated), SPEC CPU 2017 floating-point 24 per cent (estimated), HTTPS load balancing 24 per cent, memory cache 43 per cent (with lower latency), x2664 video coding 26 per cent, eda simulation 54 per cent!

Amazon's graviton 2 platform will be launched in 2020.
