CPU and System Topology

Server Description

A memory-optimized virtual machine featuring dedicated AMD EPYC processing and local SSD storage for memory-intensive workloads.

Memory OptimizedGeneral Purpose

Microsoft Azure E4a_v4 is a memory-optimized virtual machine from the EAv4 family, featuring 4 dedicated vCPUs and 32.0 GB of RAM powered by an AMD EPYC 7452 processor at 3.35 GHz. It includes 102 GB of local SSD storage and operates on the x86_64 architecture under Microsoft Hyper-V. Performance benchmarks reveal average single-core capabilities, such as in Geekbench and single-threaded compression tests, but show weaker multi-core and memory bandwidth results. With a high memory-to-vCPU ratio of 8.0 GB per core, this server is qualitatively cost-efficient for memory-intensive workloads that do not demand high-performance compute scaling. It is suited for moderate database operations, caching, and memory-heavy general-purpose applications.

0.25Score

Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
