CPU and System Topology
Server Description
An ARM-powered virtual machine featuring a high memory-to-core ratio and dedicated physical cores for memory-intensive and database workloads.
Microsoft Azure E20ps_v5 is an ARM-based virtual machine from the EPSv5 family, configured with 20 dedicated physical cores on an Ampere Altra ARMv8 Neoverse-N1 processor running at 3.0 GHz. It features 160.0 GB of RAM, establishing a high memory-to-vCPU ratio of 8.0 GB per core. While it lacks local storage and integrated GPUs, it is Premium Storage capable. Performance benchmarks indicate average multi-core capabilities, with a stress-ng multi-core score of 36041.2 and a Redis SET throughput of 27.33 million operations per second. However, single-core performance is a tradeoff, with its Geekbench single-core score falling into the bottom 25% tier. This server type is qualitatively cost-efficient for memory-intensive, highly parallelized workloads such as database hosting, static web serving, and multi-threaded data processing that benefit from dedicated ARM cores without requiring x86 instruction sets.
