Introducing the New Amazon EC2 M8a Instances: Enhanced Performance and Flexibility
Amazon Web Services (AWS) has announced the launch of the Amazon Elastic Compute Cloud (Amazon EC2) M8a instances. This new addition to the general-purpose M instance family is designed to provide users with enhanced performance and cost efficiency. Powered by the latest 5th Generation AMD EPYC processors, also known by the codename Turin, these instances are set to deliver a significant boost in processing power and memory bandwidth.
Key Improvements in M8a Instances
The M8a instances are engineered to offer up to 30% better performance per virtual CPU (vCPU) compared to their predecessors, the M7a instances. This makes them particularly suitable for applications that demand high performance and throughput, such as financial applications, gaming, rendering, and various other computational tasks. In simple terms, a vCPU in this context represents a virtual version of a physical CPU, which is a crucial part of a computer that performs calculations and tasks.
Furthermore, users can expect a 45% increase in memory bandwidth compared to the M7a instances. This significant improvement is especially beneficial for in-memory databases, distributed caches, and real-time analytics, where rapid data processing is essential.
For workloads that require high input/output operations, the M8a instances offer up to 75 Gbps of networking bandwidth and 60 Gbps of Amazon Elastic Block Store (EBS) bandwidth. Compared to the previous generation, this is a 50% improvement, allowing for faster data transfer and low-latency network communication, which is crucial for modern applications.
Instance Specifications and Flexibility
One of the standout features of the M8a instances is the lack of simultaneous multithreading (SMT). This means that each vCPU corresponds directly to a physical CPU core, allowing for more efficient processing. In practical terms, this has resulted in up to 60% faster performance for applications like GroovyJVM and up to 39% faster performance for Cassandra when compared to the M7a instances.
The M8a instances boast a feature known as instance bandwidth configuration (IBC), which provides users with the flexibility to allocate resources between networking and EBS bandwidth. This flexibility can improve database performance, query processing, and logging speeds by up to 25%.
Available in ten virtualized sizes and two bare metal options, the M8a instances cater to a wide range of deployment needs. The bare metal options, named metal-24xl and metal-48xl, offer direct access to the physical hardware, which can be beneficial for applications that require high performance and tight security.
Technical Specifications
The M8a instances feature a maximum configuration of up to 192 vCPUs with 768GiB of RAM. Here are the detailed specifications for different sizes:
- Medium: 1 vCPU, 4 GiB Memory, Up to 12.5 Gbps Network Bandwidth, Up to 10 Gbps EBS Bandwidth

- 48xlarge: 192 vCPUs, 768 GiB Memory, 75 Gbps Network Bandwidth, 60 Gbps EBS Bandwidth
- Metal-24xl: 96 vCPUs, 384 GiB Memory, 40 Gbps Network Bandwidth, 30 Gbps EBS Bandwidth
- Metal-48xl: 192 vCPUs, 768 GiB Memory, 75 Gbps Network Bandwidth, 60 Gbps EBS Bandwidth
These specifications enable the M8a instances to support a broad range of applications, from small-scale projects to large enterprise workloads.
Ideal Use Cases for M8a Instances
The M8a instances are well-suited for general-purpose applications that require a balance of compute, memory, and networking resources. They are ideal for hosting web and application services, microservices architectures, and databases where predictable performance and efficient scaling are critical. These instances are also SAP-certified, making them a reliable choice for enterprise workloads such as financial applications and enterprise resource planning (ERP) systems.
Additionally, M8a instances are effective for in-memory caching, customer relationship management (CRM), and development and test environments that demand cost efficiency and flexibility. Their versatility supports a wide spectrum of workloads while enhancing price performance for AWS customers.
Availability and Pricing
Amazon EC2 M8a instances are currently available in several AWS regions, including US East (Ohio), US West (Oregon), and Europe (Spain). Users can purchase these instances in various pricing models, including On-Demand, Savings Plans, and Spot Instances, as well as on Dedicated Hosts. For detailed pricing information, users can visit the Amazon EC2 Pricing page.
