We started the memory optimized Amazon EC2 R6a instances in July 2022, powered by 3rd generation AMD EPYC (Milan) processors running at frequencies of up to 3.6 GHz. Many customers that run workloads that depend on x86 instructions, such as B. SAP, are looking for ways to optimize their cloud usage. They take advantage of the computational choices that EC2 offers.
Today we’re announcing the general availability of new storage optimizations Amazon EC2 R7a instances Powered by 4th generation AMD EPYC (Genoa) processors with a maximum frequency of 3.7 GHz, offering up to 50 percent higher performance compared to previous generation instances. You can use this increased performance to process data faster, consolidate workloads, and reduce operational costs.
R7a instances also support AVX-512, Vector Neural Network Instructions (VNNI) and Floating point of the brain (bfloat16). These instances feature Double Data Rate 5 (DDR5) memory, which enables high-speed access to data in memory, and provide 2.25x more memory bandwidth for lower latency compared to R6a instances. Additionally, these instances support persistent memory encryption using AMD Secure Memory Encryption (SME).
These instances are SAP certified and ideal for high-performance, memory-intensive workloads such as SQL and NoSQL databases, distributed web-scale in-memory caches, in-memory databases, real-time big data analytics, and electronic design automation (EDA). ) Applications.
R7a instances have sizes of up to 192 vCPUs with 1536 GiB of RAM. Here are the detailed specifications:
|Surname||vCPUs||Memory (GiB)||Network bandwidth (Gbps)||EBS bandwidth (Gbit/s)|
|r7a.medium||1||8th||Up to 12.5||Up to 10|
|r7a.large||2||16||Up to 12.5||Up to 10|
|r7a.xlarge||4||32||Up to 12.5||Up to 10|
|r7a.2xlarge||8th||64||Up to 12.5||Up to 10|
|r7a.4xlarge||16||128||Up to 12.5||Up to 10|
R7a instances have up to 50 Gbps of enhanced networking and 40 Gbps of EBS bandwidth, which is similar to R6a instances. They have a new medium instance size that allows you to fine-tune your workloads. It offers 1 vCPUs and 8 GiB. Additionally, R7a instances allow you to attach up to 128 EBS volumes to an instance, compared to up to 28 EBS volume attachments with R6a instances. R7a instances support AES-256 compared to AES-128 in R6a instances for greater security.
R7a instances are based on AWS Nitro system and support Elastic fabric adapter (EFA) for workloads that benefit from lower network latency and highly scalable communication between nodes, such as: B. High performance computing and video processing.
Amazon EC2 R7a instances are now available in the AWS Regions: US East (Ohio), US East (N. Virginia), US West (Oregon), and EU (Ireland). As usual with Amazon EC2, you only pay for what you use. For more information, see Amazon EC2 pricing page.
