CPU and System Topology
Server Description
A high-density memory configuration featuring strong single-core AMD EPYC performance for memory-bound workloads without local storage requirements.
The Microsoft Azure E16-4as_v7 is a memory-optimized virtual machine featuring 4 dedicated vCPUs and 128.0 GB of RAM, yielding a high memory-to-core ratio of 32.0 GB per core. Powered by an AMD EPYC 9V45 processor operating at 4.5 GHz, the server delivers top-tier single-core CPU and single-threaded compression performance. However, its multi-core scaling is limited by its 2 physical cores, resulting in weak multi-threaded decompression benchmarks. The instance lacks local storage and complimentary public IPv4 addresses, relying on remote Premium Storage. This hardware profile provides a cost-efficient, resource-dense solution for memory-heavy, low-compute workloads such as in-memory databases, caching layers, and database operations, while remaining less suitable for highly parallelized computing tasks or large language model inference.
