CPU and System Topology
Server Description
An x86 memory-optimized virtual machine featuring high memory density, strong single-core performance, and support for external premium storage.
The Microsoft Azure E64-16as_v5 is an EASv5-family virtual machine configured with 16 vCPUs and 512.0 GB of RAM, yielding a high memory-to-vCPU ratio of 32.0 GB per core. Powered by an x86_64 AMD EPYC 7763 processor running at 3.525 GHz on Microsoft Hyper-V, this instance features 8 physical cores with 2 threads per core. It lacks local storage but supports Premium Storage. In benchmark testing, the server demonstrates strong single-core CPU performance and a strong PassMark memory score, both ranking in the top 25%. Conversely, its large-block write memory bandwidth is weak, falling into the bottom 25%, while multi-core CPU performance and database operations remain average. This profile makes the instance suitable for memory-intensive workloads, such as in-memory databases and caching layers, where massive memory capacity is required relative to compute resources.
