AWS Graviton4

Graviton4 is what happens when AWS builds a chip purely for what actually runs in its cloud: 96 Neoverse V2 cores post a 40% speedup for PostgreSQL and Redis, 45% for Java, and a 75% jump in memory bandwidth over Graviton3 — workload-specific gains a general-purpose chip rarely produces. It runs about 20% cheaper than equivalent x86 instances while using 60% less energy per unit of performance, which is why Netflix and SAP both report cost reductions in the 30-50% range after switching. Compared with the Apple M4 Max, it's playing a different game entirely — cloud-native throughput and cost-per-transaction over workstation power — but on those terms, it wins clearly.
