CPU and System Topology
Server Description
An x86_64 memory-optimized configuration featuring high memory density, dedicated AMD EPYC processing, and strong database and multi-core benchmark performance.
The Microsoft Azure E64as_v5 is an EASv5-family virtual machine featuring 64 dedicated vCPUs and 512.0 GB of RAM, powered by an AMD EPYC 7763 processor running at 3.7 GHz. Built on the x86_64 architecture with Microsoft Hyper-V virtualization, this memory-optimized instance offers a high 1:8 vCPU-to-RAM ratio. It lacks local storage and GPUs but supports Premium Storage. Performance benchmarks place this server in the top 10% for Passmark memory scores and the top 25% for multi-core CPU execution, Redis SET operations, and database operations. Conversely, large-block uncached memory bandwidth and large-model LLM text generation perform in the average and poor tiers, respectively. The server is designed for memory-intensive workloads, including relational databases, in-memory data stores like Redis, and large-scale software compilation, where high memory density and strong multi-core processing are required.
