AWS Graviton5: 192 Cores, 5x Cache - ARM Takes Over the Data Center
AWS doubled the core count on their flagship ARM processors with Graviton5—192 cores in a single socket, 5x L3 cache (180MB), and 3nm fabrication. We go deep on ARM vs x86 architecture, cache hierarchy latencies, NUMA elimination benefits, formal verification security proofs, and a complete migration framework with multi-arch CI/CD patterns. With 98% of top EC2 customers already on Graviton, the ARM tipping point is now.
Duration: ~22 minutes
This episode covers:
- 192-core single socket design eliminating NUMA overhead
- 180MB L3 cache enabling database working sets to fit entirely in cache
- Nitro Isolation Engine with formal verification (mathematical security proofs)
- Real customer results from Atlassian, Honeycomb, and SAP
- 4-question framework for evaluating ARM migration
- 5-point action plan for platform teams
- Regional availability considerations
News segment: State of Platform Engineering 2026 report shows platform engineering practices "shifting down" to mid-market companies.
