Server Description
A memory-optimized x86 server featuring one terabyte of RAM and high-bandwidth networking for demanding in-memory database workloads.
Amazon Web Services r6a.32xlarge is an x86_64 memory-optimized server instance running on the Nitro hypervisor. It features an AMD EPYC 7R13 processor with 128 vCPUs and 64 physical cores clocked at 3.6 GHz, paired with 1024.0 GB of DDR4 memory. The processor supports AVX, AES, and SHA_NI instructions, but lacks AVX-512 support. The instance lacks local storage and dedicated GPUs, but provides a baseline network bandwidth of 50 Gbps. Benchmark results show top-tier multi-core CPU performance and memory bandwidth, with Redis SET operations reaching 136.38 million operations per second. Single-core performance and text processing tasks fall into average ranges. This instance offers qualitative cost efficiency for memory-intensive workloads by providing a high memory-to-vCPU ratio without the added cost of local NVMe drives. It is suited for in-memory databases, large-scale caching, and memory-bound enterprise applications.
