Server Description
A dedicated 64-vCPU compute-optimized platform with DDR5 memory and advanced matrix extensions for high-throughput processing and compilation workloads.
Compute Optimized
Amazon Web Services c7i.16xlarge is a compute-optimized instance built on the Nitro hypervisor, featuring 64 dedicated vCPUs from an Intel Xeon 8488C processor running at 3.2 GHz. It is equipped with 128.0 GB of DDR5 memory at 5 GHz, yielding a 1:2 vCPU-to-RAM ratio, but lacks local storage and GPU hardware. The processor supports AVX-512 and Intel Advanced Matrix Extensions (AMX), driving strong benchmark results in the top 25% tier, including a PassMark CPU score of 70832.71 and 72.7 million Redis SET operations per second. While uncached memory write speeds of 75.45 GB/sec remain in the average tier, the instance excels in compute-heavy tasks. It is suited for workloads such as software compilation, static web serving, cryptographic processing, and CPU-based machine learning inference.
