Inside Graviton4: How AWS's New Chip Cuts EC2 Costs by 20% for Compute-Heavy Workloads

AWS recently launched Graviton4, its fourth-generation custom silicon chip built specifically for EC2 workloads. Designed from the ground up for cloud-native compute, Graviton4 delivers a headline 20% reduction in EC2 costs for compute-heavy workloads compared to previous-generation Graviton instances, while outperforming x86-based equivalents on price-performance for the same use cases.

Graviton4 Architecture: Built for Efficiency

Graviton4 is fabricated on TSMC's 3nm process node, a major leap from the 5nm process used in Graviton3. It uses ARM's Neoverse V2 core architecture, which brings support for ARMv9.2 instruction sets including Scalable Vector Extensions 2 (SVE2) for accelerated machine learning and scientific computing workloads.…
