CPU and System Topology

Server Description

A memory-optimized virtual machine featuring dedicated AMD EPYC processing for database operations, software compilation, and multi-threaded workloads.

Memory OptimizedGeneral Purpose

Microsoft Azure E48as_v6 is an Eav6-family virtual machine configured with 48 vCPUs and 384.0 GB of RAM, yielding a memory-to-vCPU ratio of 8.0 GB per core. Powered by a dedicated AMD EPYC 9V74 processor running at 3.7 GHz, this x86_64 instance lacks local storage and GPU accelerators but supports Premium Storage. Performance benchmarks show strong single-core and multi-core CPU execution, alongside high cached memory bandwidth and strong database operations. However, uncached large-block memory bandwidth and large-model LLM text generation are limited, representing key performance tradeoffs. This server is designed for memory-intensive workloads, database management, software compilation, and multi-threaded data decompression.

Workload Profiles

2.2Score

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.
