      Server Description

      A memory-optimized instance pairing 256 GB of RAM with 25 Gbps network bandwidth for memory-intensive, multi-threaded workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r5n.8xlarge is a memory-optimized instance featuring 32 vCPUs and 16 physical cores powered by an Intel Xeon 8259CL processor running at 3.1 GHz. Built on the Nitro hypervisor, it provides 256.0 GB of DDR4 memory, yielding a high 8.0 GB of RAM per core, but lacks local storage and GPU accelerators. Network connectivity is supported by a baseline bandwidth of 25 Gbps. Benchmark data shows a distinct tradeoff: single-core CPU performance is weak, falling in the bottom 25%, while multi-core performance, memory bandwidth, and Redis SET operations achieve average ratings in the middle 50%. This hardware profile offers qualitative cost efficiency for memory-heavy workloads that scale across multiple threads rather than relying on single-threaded speed. It is best suited for in-memory databases, caching layers, and distributed data processing applications.
