  • Fast local storage
  • CPU virtualization

The system consists of Nitro cards, a Nitro security chip, and hypervisor. It also includes AWS Nitro Enclaves and NitroTPM as security features.

The Nitro System offloads the virtualization, storage, and networking functions.

It is then dedicated to the hardware and software to reduce costs and improve performance.

C7g Instance Availability

The C7g instances are available in eight sizes with 1, 2, 4, 8, 16, 32, 48, and 64 vCPUs.

C7g instances support configurations up to 128 GiB of memory and 30 Gbps of network performance.

It also supports 20 Gbps of Amazon Elastic Block Store (EBS) performance.

You can see the features of each instance below -

Comparing Graviton 3 to Previous Generation Graviton 2

Comparing Graviton 3 to Previous Generation Graviton 2

Graviton 2 had Arm's Neoverse N1 cores. Graviton 3 has Neoverse N2 or Neoverse V1 cores.

The previous Graviton processor has a 64-core and 2.5 GHz clock speed. Graviton 3 has greater width, so twice as much data is processed in a single clock cycle.

The instructions each core can work on concurrently have increased from 5 to 8 per cycle.

Graviton 3 is not using extra transistors to pack more cores. AWS adds transistors to improve memory performance.

Graviton 2 instances already have a lot of memory bandwidth per VCPU. More memory bandwidth has been added to Graviton 3 instances.

Each Graviton 3 core has 50% more memory bandwidth than Graviton 2.

It helps improve the performance of memory-intensive scientific applications such as:

  • Computational fluid dynamics
  • Geoscientific simulations
  • Seismic processing.

Performance Testing for Graviton 3

Performance Testing for Graviton 3

AWS noted the following performance improvements in Graviton 3-

  • SpecINT2017 and SPECfp2017

In server benchmarks such as SpecINT2017 it is 30 percent. In SpecFP2017 it is a 60 percent increase in performance.

  • NGINX

Nginx is a web server and load balancer. The performance testing for NGINX saw a 2x increase in c7g instances compared to c6g.

  • Node.js

The performance test was carried out on Node.js applications such as Acme Air. It is a sample application that does flight schedules.

The test found 37% higher performance on NGINX from Graviton 2 to Graviton 3.

  • Video Encoding

Video encoding is one of the large cloud-based workloads, as many videos are transmitted on the internet.

AWS used libx264 to encode uncompressed video for the highest quality.

The results showed that 49% more frames per second are encoded on the Graviton 3 system vs. Graviton 2.

  • Computational Fluid Dynamics

F1 company uses CFD simulations to see how downforce works on the cars. Graviton 3 is a 40% faster runtime for CFD workloads than Graviton 2.
