Graviton5 CPU Benchmarks: 30% Geo Mean Improvement Over Graviton4

After originally announcing Graviton5 last December, recently AWS finally made the M9g and M9gd instances generally available as the first featuring these new in-house ARM server processors for the EC2 cloud. Graviton5 makes use of Arm Neoverse-V3 cores compared to Neoverse-V2 with Graviton4, support up to 192 cores, and feature a higher 3.3GHz clock speed compared to 2.8GHz on the prior-generation Graviton CPUs. Here is an initial look at how the Graviton5 processor performs over Graviton4.

Why this matters
Why now

AWS continues its annual cadence of Graviton releases, with Graviton5 deploying as cloud compute demand remains high, particularly for AI workloads.

Why it’s important

AWS's continuous improvement in custom ARM server CPUs strengthens its competitive advantage in cloud infrastructure and silicon, offering cost and performance benefits to customers.

What changes

Cloud users now have access to significantly more powerful and efficient AWS-designed CPUs, potentially accelerating the adoption of custom silicon over traditional x86 alternatives in the cloud.

Winners
  • · AWS
  • · Cloud customers focused on cost/performance
  • · ARM ecosystem
Losers
  • · Intel
  • · AMD
  • · Generic x86 cloud instances
Second-order effects
Direct

Increased market share for AWS Graviton instances due to superior price/performance.

Second

Accelerated investment by other cloud providers and large enterprises into custom silicon development to compete with AWS.

Third

Further commoditization of traditional server CPU markets as hyperscalers increasingly rely on in-house designs.
