Server Description
A high-density, compute-optimized platform featuring 192 vCPUs and DDR5 memory for demanding parallel processing and high-throughput enterprise workloads.
Amazon Web Services c8i.48xlarge is a compute-optimized instance featuring 192 vCPUs and 96 physical cores powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. It is equipped with 384.0 GB of DDR5 memory, a 75 Gbps baseline network bandwidth, and no local storage. Operating on the AWS Nitro hypervisor, the instance delivers top-tier multi-core CPU and memory bandwidth performance, ranking in the top 10% for multi-threaded decompression, software compilation, and database operations. While single-core performance is moderate, its support for advanced instruction sets like Intel AMX and AVX-512 enables exceptional parallel processing and cryptography capabilities. This instance is highly efficient for compute-intensive workloads, including large-scale LLM prompt processing, ray tracing, and high-throughput web serving.
