CPU and System Topology
Server Description
A memory-optimized virtual server featuring high memory density and top-tier single-core performance for memory-bound enterprise workloads.
The Microsoft Azure E64-16as_v7 is a memory-optimized server from the Easv7 family, powered by an AMD EPYC 9V45 processor. It features 16 dedicated vCPUs across 8 physical cores running at 4.5 GHz, paired with 512.0 GB of system memory. This configuration provides a high resource density of 32.0 GB of RAM per vCPU. While the server lacks local storage and integrated GPUs, it is Premium Storage capable. In benchmark evaluations, the E64-16as_v7 delivers top-tier single-core CPU performance, single-threaded compression, and small-model LLM text generation, alongside strong memory performance. Multi-core and database operations perform at average levels. This server is highly suited for memory-intensive workloads, including in-memory databases, caching systems, and enterprise applications requiring substantial memory capacity without proportional vCPU overhead.
