Starting today, you can use our first 6th generation Amazon Elastic Compute Cloud (EC2) General Purpose instance: the M6g. The "g" stands for "Graviton2", our next generation Arm-based chip designed by AWS (and Annapurna Labs, an Amazon company), utilizing 64-bit Arm Neoverse N1 cores. These processors support 256-bit, always-on, DRAM encryption. They also include dual […]
Starting today, you can use our first 6th generation Amazon Elastic Compute Cloud (EC2) General Purpose instance: the M6g. The "g" stands for "Graviton2", our next generation Arm-based chip designed by AWS (and Annapurna Labs, an Amazon company), utilizing 64-bit Arm Neoverse N1 cores.

These processors support 256-bit, always-on, DRAM encryption. They also include dual SIMD units to double the floating point performance versus the first generation Graviton, and they support int8 / fp16 instructions to accelerate machine learning inference workloads. You can read this full review published by AnandTech for in-depth details.

The M6g instances are available in 8 sizes with 1, 2, 4, 8, 16, 32, 48, and 64 vCPUs, or as bare metal instances. They support configurations with up to 256 GiB of memory, 25 Gbps of network performance, and 19 Gbps of EBS bandwidth. These instances are powered by AWS Nitro System, a combination of dedicated hardware and a lightweight hypervisor.

For those of you running typical open-source application stacks, generally deployed on x86-64 architectures, migrating to Graviton will give you up to 40% improvement on cost-performance ratio, compared to similar-sized M5 instances. M6g instances are well-suited for workloads such as application servers, gaming servers, mid-size databases, caching fleets, web tier and the likes.

We ran an extensive preview program to collect customer feedback on this 6th generation instance type. For example, Honeycomb uses 30% fewer instances vs C5, KeyDB observes 65% better performance and 20% cost reduction vs M5, Inter Systems reported 28% performance improvement and 20% cost reduction compared to equivalent M5 instances, and…
