The processor family is distinguished by its lower energy use relative to x86-64, static clock rates, and lack of simultaneous multithreading.
[1] In 2018, AWS released the first version of Graviton suitable for open-source and non-performance-critical scripting workloads as part of its A1 instance family.
[4] In May 2022, AWS made available Graviton3 processors as part of its seventh generation EC2 instances, offering a further 25% better compute performance over Graviton2.
[11] The first Graviton CPU has 16 Cortex A72 cores, with ARMv8-A ISA including Neon, crc, crypto.
It also includes hardware acceleration for floating-point math, SIMD, plus AES, SHA-1, SHA-256, GCM, and CRC-32 algorithms.
[13] The Graviton2 CPU has 64 Neoverse N1 cores, with ARMv8.2-A ISA including 2×128 bit Neon, LSE, fp16, rcpc, dotprod, crypto.
