Server Description
A memory-optimized x86 server featuring dedicated Intel Xeon processing, high-speed local NVMe storage, and balanced 25 Gbps network bandwidth.
The Amazon Web Services r6idn.4xlarge is a memory-optimized instance featuring 16 vCPUs, 8 physical cores, and 128.0 GB of DDR4 memory powered by a 3.5 GHz Intel Xeon 8375C processor. Built on the Nitro hypervisor, it includes a bundled 950 GB NVMe SSD and a 25 Gbps baseline network interface. The processor supports AVX-512 and cryptographic acceleration, delivering average performance in CPU and memory bandwidth benchmarks, alongside strong text generation speeds of 265.24 tokens/sec for small language models. With a high memory-to-vCPU ratio of 8.0 GB per core and high-speed local storage, this instance is qualitatively cost-efficient for workloads requiring dense memory and fast local I/O. It is suited for database operations, caching layers, and memory-intensive enterprise applications.
