Server Description
A bare-metal, memory-optimized platform featuring ninety-six dedicated AMD EPYC cores and high-speed DDR5 RAM for demanding enterprise database workloads.
Memory OptimizedCompute Optimized
Amazon Web Services r8a.metal-24xl is a memory-optimized bare-metal server featuring 96 dedicated physical cores powered by an AMD EPYC 9R45 processor running at 4.5 GHz. Built on the x86_64 architecture, it is equipped with 768.0 GB of DDR5 memory operating at 6 GHz, yielding 8.0 GB of RAM per core. The server does not include local storage or GPUs, but provides a baseline network bandwidth of 40 Gbps. Benchmark results place this instance in the top tier for single-core and multi-core CPU performance, memory bandwidth, and database operations, with Redis SET performance reaching 235.68 million operations per second. It is highly suited for memory-intensive workloads, including large-scale in-memory databases, enterprise applications, software compilation, and CPU-based large language model inference.
