AWS introduced two EC2 instances using Graviton2 processors based on its own Arm technology. These proprietary processors of the public cloud giant should eventually deliver more computing power than other types of processors.

The newly released EC2 C6g and R6g instances are the second type of instances that AWS released this year. Last month, all EC2 M6g instances with Arm-based Graviton2 processors were released. According to the public cloud giant, these instances are especially suitable for application servers, microservices, gaming servers, mid-size data stores and caching applications. The currently released instances are primarily focused on server infrastructure.

Computing power and memory capacity

The C6g instance is intended to optimise computing power, while the R6g focusses on memory capacity. Both versions, with the Graviton2 Arm-core processors, should be faster than comparable processors, such as the Gen2 Intel Cascade Lake and the Intel Skylake-SP Xeon processors. They should also outperform both up to 40 times. Reusing Arm technology shows that AWS increasingly prefers this technology.

Technical details

The new EC2 Graviton2 instance types both have a 7nm process node, 64-bit Arm Neoverse N1 CPU cores each with 1MB of L2 cache plus 32MB of shared L3 cache.

The computing power-optimised C6g version is available in different configurations. These configurations start from a single vCPU with 2GB RAM, 10GE network capacity and a 4.750 Mbps pipe to the Amazon Elastic Block Store (EBS) service. The most extensive configuration can be rented with 64 vCPUs, the Graviton2 has 64 cores, 128GB RAM, 25GE network capacity and a 19.000 Mbps link to Amazon EBS.

The AWS EC2 Graviton2 Rg6 instances have the same configurations as the C6g instances. They offer the same capacities but primarily focus on memory capacity.
