• Graviton4, AWS’s 4th‑gen custom server CPU, unveiled at re:Invent 2023, built by Annapurna Labs. • It packs 50% more cores and 75% higher memory bandwidth than Graviton3. • Performance gains: 30% faster overall, 40% quicker for databases, 45% faster Java workloads. • Architecture uses Arm Neoverse V2, chiplet design, and SVE support for vector workloads. • New R8g EC2 instances previewed today; more Graviton4‑based instances slated for next year. • AWS’s rapid 1‑year cadence from Graviton2 to Graviton4 shows aggressive innovation cycle.
Article Summaries:
- Amazon announced its fourth‑generation Graviton processor (Graviton4) at AWS re:Invent 2023. Built by Annapurna Labs, the chip uses Arm’s Neoverse V2 core and supports Armv9.0 ISA, delivering 96 cores-1.5× the count of Graviton3-and 30 % higher overall performance. Memory bandwidth rises 75 % to 537.6 GB/s with 12 DDR5‑5600 channels, and PCIe 5.0 lanes triple to 96. Each core has 2 MiB L2 cache, doubling the per‑core cache of the previous generation. AWS also previewed new R8g EC2 instances powered by Graviton4, with additional instances slated for early next year.
