Server Description
A balanced x86 general-purpose instance featuring high-speed DDR5 memory and advanced Intel matrix extensions for enterprise workloads and CPU inference.
Amazon Web Services m8i.12xlarge is a general-purpose instance featuring 48 vCPUs powered by an Intel Xeon 6975P-C processor running at 3.9 GHz on the Nitro hypervisor. It includes 192.0 GB of DDR5 memory at 7 GHz, providing a balanced 1:4 vCPU-to-RAM ratio, but lacks local storage and dedicated GPUs. Network performance is supported by a 22 Gbps baseline bandwidth. Benchmark results show strong performance, particularly in memory bandwidth, software compilation, and database operations, with Redis SET operations reaching 89.2 million operations per second. The processor's Intel AMX and AVX-512 extensions enable top-tier performance in image and text processing, as well as strong prompt processing for small and medium language models. This instance is highly suited for enterprise databases, static web serving, software development pipelines, and CPU-based machine learning inference.
