Server Description
A memory-optimized, x86-64 server featuring high-speed DDR5 RAM and advanced Intel matrix extensions for memory-intensive enterprise workloads.
Amazon Web Services r7i.4xlarge is a memory-optimized instance featuring 16 vCPUs and 8 physical cores powered by a dedicated 3.2 GHz Intel Xeon 8488C processor. It is equipped with 128.0 GB of high-speed 5 GHz DDR5 memory, providing 8.0 GB of RAM per core, but includes no local storage. Built on the AWS Nitro hypervisor, the instance supports advanced instruction sets such as AVX-512 and Intel AMX. Benchmarks show strong single-threaded performance, with a Geekbench single-core score of 2141.0 and top-tier text processing and small-model LLM text generation speeds. Multi-core performance is solid, as evidenced by a PassMark CPU score of 26176.98 and 21.24 million Redis SET operations per second. This profile makes the r7i.4xlarge highly suitable for memory-intensive databases, text processing, and enterprise applications requiring high memory bandwidth without local storage.
