Server Description
A high-frequency, dedicated AMD EPYC instance featuring DDR5 memory and 100 Gbps networking for demanding compute and database workloads.
Amazon Web Services m8azn.12xlarge is a general-purpose instance featuring 48 dedicated physical cores powered by an AMD EPYC 9R05 processor running at 5.0 GHz. Built on the Nitro hypervisor, it includes 192.0 GB of DDR5 memory operating at 6 GHz, providing 4.0 GB per core. The instance lacks local storage and dedicated GPUs, relying instead on network-attached storage and offering a baseline network bandwidth of 100 Gbps. Benchmark results place this instance in the top 10% for single-core and multi-core CPU performance, memory bandwidth, and database operations. It supports advanced instruction sets including AVX-512 and AES cryptography. This hardware profile delivers high resource density and processing efficiency, making it suitable for demanding workloads such as software compilation, high-throughput database operations, static web serving, and CPU-based language model inference.
