Amazon’s Elastic Compute Cloud R8g instances use the high-performance Graviton4 chip and have been in preview since 2017. Last Novemberwhich is now available to everyone using AWS. AWS says it focused on energy efficiency as well as power and performance when creating Graviton4.
R8g instances are accessible in the US East (N. Virginia), US East (Ohio), US West (Oregon), and Europe (Frankfurt) AWS regions.
Amazon EC2 R8g instances allow choice of cloud processors
Graviton-based Amazon EC2 instances are AWS cloud instances for servers and data centers. AWS says the Graviton4 processors deliver 30% higher performance than the AWS Graviton3-based Amazon EC2 R7g instances. This means the Graviton4 processors are particularly well suited for workloads that require large amounts of memory, such as high-performance databases, in-memory caches, and real-time big data analytics.
If you are choosing a processor for running cloud workloads on Amazon EC2 instances, you might be considering the x86 architecture or the Graviton family (or Mac Instances).
What does Graviton4 bring to Amazon EC2 R8g instances?
Amazon said that the R8g instances equipped with Graviton4 have been improved in many aspects compared to the R7g instances and Graviton3:
- Improve performance of web applications by up to 30%.
- Improve database performance by up to 40%.
- Large Java applications can be up to 45% faster.
- The number of virtual CPUs has increased by up to 3 times (up to 48xl).
- Memory increased 3x (up to 1.5TB).
- 75% increase in memory bandwidth.
- 2x more L2 cache compared to R7g instances.
- Network bandwidth increased from 30 Gbps to 50 Gbps.
- EBS bandwidth is up to 40 Gbps compared to 20 Gbps EBS.
R8g instances leverage offloaded CPU virtualization, storage, and networking functions to improve performance and security. R8g instances can host applications written in major programming languages as well as Linux-based workloads.
For the first time, Graviton instances are available in two bare metal sizes (metal-24xl and metal-48xl) in R8g instances.

Graviton4 is dedicated to improving energy efficiency
AWS calls the Graviton4 the “most energy-efficient processor we’ve ever designed,” according to a press release. AWS’s approach to improving efficiency for memory-intensive workloads with EC2 includes offloading some CPU virtualization, storage, and networking functions to dedicated hardware and software.
AWS claims that customers can use Graviton4 instances to reduce energy consumption and carbon footprint by up to 60% compared to other Amazon EC2 instances.
“These instances enable organizations to achieve their sustainable innovation goals faster and with better price/performance than comparable Amazon EC2 instances.” Rahul Kulkarni, director of product management for EC2 at AWS, said in an email to TechRepublic.
Is Amazon EC2 R8g Right for Your Business?
As mentioned above, organizations looking to host high-performance workloads on the cloud have a variety of options beyond just choosing a chip. Amazon’s EC2 cloud computing instances compete with other infrastructure-as-a-service providers, such as:
Depending on the size of your workload, other Amazon Web Services may also be suitable.
