Server Description
A memory-optimized instance featuring ninety-six vCPUs, high-speed network bandwidth, and substantial memory capacity for demanding database and caching workloads.
Amazon Web Services r5n.24xlarge is an x86_64 memory-optimized instance featuring 96 vCPUs and 768.0 GB of DDR4 RAM. Powered by an Intel Xeon 8259CL processor running at 3.1 GHz, it operates on the Nitro hypervisor with dedicated CPU allocation. The instance lacks local storage and GPUs but delivers a baseline network bandwidth of 100 Gbps. Benchmark results show strong multi-core CPU performance, high memory bandwidth, and strong Redis SET operations. However, single-core performance and LLM text generation speeds are weak. Qualitatively, the instance offers high memory density per vCPU, making it cost-efficient for memory-bound applications. It is suited for large-scale databases, in-memory caching, and multi-threaded enterprise workloads. The 1:8 vCPU-to-RAM ratio supports memory-intensive tasks, though storage-heavy workloads must rely on network-attached storage due to the absence of local NVMe drives.
