CPU and System Topology
Server Description
A memory-optimized virtual machine featuring high memory density, dedicated AMD EPYC processing, and local SSD storage for database workloads.
Microsoft Azure E20as_v4 is an x86_64 memory-optimized virtual machine powered by an AMD EPYC 7763 processor. It delivers 20 dedicated vCPUs, 160.0 GB of RAM, and 328 GB of local SSD storage. Operating under Microsoft Hyper-V, this instance offers a high memory-to-vCPU ratio of 8.0 GB per core. Benchmarks reveal strong single-core CPU and memory performance, while multi-core processing, memory bandwidth, and database operations align with average tiers. However, the instance exhibits weak to poor performance in LLM inference tasks, making it unsuitable for large-scale AI workloads. The E20as_v4 is qualitatively cost-effective for memory-heavy enterprise applications, relational databases, and caching systems that benefit from high resource density without requiring GPU acceleration.
