CPU and System Topology
Server Description
A compute-optimized instance featuring three hundred eighty-four virtual cores, DDR5 memory, and top-tier multi-threaded capabilities for parallel processing.
Amazon Web Services c8i.96xlarge is an x86_64 compute-optimized instance featuring 384 vCPUs and 192 physical cores powered by an Intel Xeon 6975P-C processor at 3.9 GHz. Equipped with 768.0 GB of DDR5 memory and a 100 Gbps network baseline, this Nitro-based server lacks local storage and GPU accelerators. Benchmarks indicate top-tier multi-core CPU performance, memory bandwidth, and database operations, though single-core execution and LLM text generation speeds are comparatively limited. The instance is designed for highly parallelized compute workloads, including software compilation, multi-threaded decompression, and high-throughput web serving.
