Server Description
A high-density bare-metal compute platform featuring 192 AMD EPYC cores and DDR5 memory for demanding parallel processing workloads.
Compute OptimizedGeneral Purpose
Amazon Web Services c8a.metal-48xl is a bare-metal, compute-optimized server featuring 192 dedicated physical cores and 192 vCPUs powered by AMD EPYC 9R45 processors running at 4.5 GHz. The hardware configuration includes 384.0 GB of high-speed DDR5 memory at 6 GHz, yielding a 1:2 vCPU-to-RAM ratio, with no local storage or onboard GPUs. It delivers a baseline network bandwidth of 75 Gbps. Benchmarks place this instance in the top 10% for multi-core CPU performance, memory bandwidth, and database operations. It supports advanced vector extensions (AVX-512) and cryptographic acceleration. This server is engineered for high-density compute workloads, large-scale web serving, Redis databases, and LLM prompt processing.
