AWS Graviton is a family of 64-bit ARM-based CPUs designed by the Amazon Web Services (AWS) subsidiary Annapurna Labs. The processor family is distinguished by its lower energy use relative to x86-64 , static clock rates , and lack of simultaneous multithreading .

AWS Graviton is a family of processors designed to deliver the best price performance for your cloud workloads running in Amazon Elastic Compute Cloud (Amazon EC2). Choose the AWS Graviton-based instance that best meets your needs.

2022年5月29日 · Graviton 3 was the first ARM CPU to introduce the SVE instruction set to a widely accessible server CPU. Before Graviton 3’s general availability, Neoverse N1 dominated the ARM server landscape. AWS’s previous flagship offering, Graviton 2, implements 64 Neoverse N1 cores at 2.5 GHz.

2021年11月30日 · At its annual re:Invent conference, AWS today announced the newest generation of its Arm-based Graviton processors: the Graviton 3. The company promises that the new chip will be 25 percent...

2021年12月2日 · Today Amazon announced Graviton3 and a custom SSD controller. The first impressive in-housing effort was with the AWS Nitro years back. Nitro extends from the custom hypervisor, a security chip, and the powerful Nitro networking cards.

2022年1月4日 · The Graviton family of Arm server chips designed by the Annapurna Labs division of Amazon Web Services is arguably the highest volume Arm server chips the datacenter market today, and they have precisely one – and only one – customer.

2023年2月13日 · Both types are powered by the latest generation AWS Graviton3 processors, and are designed to deliver up to 25% better performance than the equivalent sixth-generation (M6g and R6g) instances, making them the best performers in EC2.

2022年5月23日 · Our next generation, Graviton3 processors, deliver up to 25 percent higher performance, up to 2x higher floating-point performance, and 50 percent faster memory access based on leading-edge DDR5 memory technology compared with Graviton2 processors.

Graviton 3 is 60 percent more efficient over comparable EC2 instances with up to 40 percent better performance. This guide focuses on the cost benefits of using Graviton, but it's important to note that Graviton offers the additional benefits of performance improvements and improved environmental sustainability.

2021年12月2日 · Here is how the memory bandwidth stacks up per vCPU on the three different Graviton processors on the four different EC2 instances: These appear to be measured bandwidth using a benchmark, not peak theoretical memory bandwidth. Our guess is that it is the STREAM Triad memory test.
