Server Description
A dedicated 64-vCPU compute-optimized platform featuring Intel Xeon processors, tailored for parallel processing and high-throughput multi-core workloads.
Compute OptimizedGeneral Purpose
Amazon Web Services c6i.16xlarge is an x86_64 compute-optimized instance powered by an Intel Xeon 8375C processor running at 3.5 GHz. It features 64 dedicated vCPUs (32 physical cores) and 128.0 GB of DDR4 memory, establishing a 2.0 GB per vCPU ratio. The architecture supports AVX-512 extensions and cryptographic acceleration. While the instance lacks local storage and dedicated GPUs, it provides a baseline network bandwidth of 25 Gbps. Benchmarks indicate strong multi-core capabilities, with high scores in software compilation, ray tracing, and static web serving throughput. Conversely, single-core performance and memory bandwidth align with average tiers. This instance delivers a balanced compute-to-memory profile, making it suitable for parallel processing tasks, database operations, and CPU-based language model inference.
