Server Description
An Arm-based, memory-optimized server featuring massive memory bandwidth and dedicated physical cores for high-throughput database and enterprise workloads.
Amazon Web Services x8g.48xlarge is an Arm-based, memory-optimized server instance designed for memory-intensive enterprise workloads. Powered by the AWS Nitro hypervisor, it features 192 dedicated physical cores on the AWS Neoverse-V2 processor running at 2.7 GHz, paired with 3072.0 GB of RAM. This configuration delivers a high memory-to-core ratio of 16.0 GB per core. While the instance lacks local storage and GPU accelerators, it provides a 50 Gbps baseline network bandwidth. Benchmark data highlights top-tier multi-core CPU performance, exceptional memory read/write bandwidth, and outstanding database transaction speeds, though single-core performance remains average. The absence of x86 vector extensions like AVX is an architectural tradeoff. This instance is highly suited for in-memory databases, large-scale software compilation, and high-throughput web serving.
