CPU and System Topology
Server Description
A memory-optimized virtual machine featuring a dedicated Intel Xeon processor and high memory density for memory-bound, compute-light workloads.
Microsoft Azure E4bs_v5 is an EBSv5-family virtual machine featuring 4 vCPUs and 32.0 GB of RAM, running on a dedicated Intel Xeon 8370C processor at 2.8 GHz. Built on the x86_64 architecture, it provides 2 physical cores with hyper-threading and a 48 MB L3 cache, but lacks local storage and GPUs. Performance benchmarks show average single-core capabilities, such as in Geekbench and stress-ng tests, but multi-core scaling and memory bandwidth fall into the bottom 25%. This memory-optimized profile, with 8 GB of RAM per vCPU, is qualitatively cost-efficient for memory-heavy, compute-light applications. It is appropriate for memory-cached workloads, text processing, and small database operations utilizing remote Premium Storage.
