CPU and System Topology
Server Description
An AMD-powered virtual machine delivering 512 GB of RAM and local SSD storage for memory-intensive enterprise database workloads.
Microsoft Azure E64-16as_v4 is a memory-optimized virtual machine from the EASv4 family, featuring 16 dedicated AMD EPYC 7763 vCPUs and an exceptionally large 512.0 GB of RAM. Operating on the x86_64 architecture under Microsoft Hyper-V, it includes 885 GB of local SSD storage and supports Premium Storage. The server delivers strong single-core CPU and memory benchmark performance, though its uncached memory write bandwidth is relatively weak. With 32.0 GB of RAM per core, this instance is qualitatively cost-efficient for memory-intensive workloads, making it best suited for in-memory databases, caching layers, and enterprise applications.
