Amazon bets on 3rd generation AMD EPYC CPUs

It’s official, Amazon Web Services (AWS) has expanded its cloud service offering through Amazon EC2 M6a instances, based on the new 3rd generation AMD EPYC processors. This is a very important move by the American giant since, thanks to its commitment to the new AMD processors, has been able to improve the price-performance ratio by up to 35% (compared to previous generation instances), and has reduced costs by 10% versus comparable instances based on the x86 architecture.

Lynn Comp, Corporate Vice President of Cloud Business at AMD, commented:

“Our 3rd generation AMD EPYC processors provide Amazon EC2 users with excellent scalability and an impressive price-performance ratio compared to the previous generation of Amazon EC2 M5a instances. This announcement shows our strong collaboration and highlights our overall momentum in cloud infrastructure. Our work with AWS exemplifies our commitment to providing end users with innovation and performance for their cloud workloads and environments. “

The 3rd generation AMD EPYC processors are based on Zen 3, a revolutionary architecture that achieved a significant improvement in terms of CPI compared to Zen 2, thanks to the unification of the L3 cache available per chiplet, and also to other changes that affected the jump predictor, the front end, the cache prefetch and the adjustment of latencies at the cache level.

According to Amazon Web Services, the new third-generation AMD EPYC-based instances are certified by SAP, ready to handle a wide variety of workloads, including from web and application servers to back-end servers focused on business applications, microservices, servers for multiplayer modes in video games and also for application development.

Each instance is available in ten different sizes, with the 48xlarge being the most powerful. This has a total of 192 virtual CPUs and 768 GB of RAM memory. The bandwidth they can offer reaches a maximum peak of 50 Gbps, and they are built on the AWS Nitro system, a combination of dedicated hardware and lightweight hypervisor, which delivers almost all the computing resources and memory of the hardware to the instances.

There is no doubt that we are facing a significant generational leap, although we must not overlook that the fact that Amazon Web Services has trusted AMD is everything an indication of how well the Sunnyvale company has done with Zen 3.
