Amazon has just released its second-generation self-designed server chip, the Graviton 2, the strongest ARM-platform processor to date, no less than Intel’s top-of-the-line XEON platinum. Amazon Graviton2 uses ARM’s latest Neoverse N1 CPU architecture, built by its own design team, to stack up to 64 cores, four times as many as the first generation (twice as many as previously reported), and uses a top-level configuration with a 1MB secondary cache for each core, for a total of 64MB. All cores share a 32MB level 3 cache.
The 64 cores feature mesh bus (Mesh Fabric) interconnections with combined bandwidth of up to 2TB/s. Supports eight-channel DDR4-3200 memory, hardware AES-256 memory encryption, and 64 PCIe 4.0.
Officials say the Graviton 2 is up to seven times the performance of the first generation and up to five times faster memory access.
Amazon has also launched a series of sixth-generation examples based on Graviton 2, including M6g, R6g, C6g, with varying configurations of up to 256GB of memory.
Amazon also compares it to fifth-generation instances with Intel Xeon platinum (up to 3.1GHz), with a comprehensive lead in single core performance: SPECjvm 2008 (estimated), CPU 2017 integers , 44% (estimated), SPEC CPU 2017 floating points , and 24% ( Estimated), HTTPS load balancing , memory cache , 43% (lower at the same time), x2664 video encoding , EDA simulation , s.54%!
Amazon’s Graviton 2 platform will be launched in 2020.
