📅 November 2025 ✍️ TCOIQ Analysis ⚠️ High Impact

AWS launched Graviton4 as R8g instances. 30% better compute, 50% better ML performance vs R7g at the same price. SAP HANA certified up to 768GB. Same ARM ISA — existing binaries run without recompilation.

TCOIQ: Immediate action for any team running R6g or R7g — zero-cost 30% performance upgrade. For new deployments R8g is the default ARM choice. At r8g.2xlarge ($0.4032/hr) GCP n2-highmem-8 and Azure E8s v5 are both more expensive for equivalent memory.
