      CPU and System Topology

      Server Description

      A balanced general-purpose instance featuring dedicated AMD EPYC processors, strong single-core performance, and 128 GB of memory.

      General Purpose

      Alibaba Cloud ecs.g8a.8xlarge is a general-purpose instance featuring 32 dedicated vCPUs and 128.0 GB of RAM, powered by an AMD EPYC 9T24 processor running at 2.7 GHz. Built on the KVM hypervisor, this x86_64 server provides a balanced 4.0 GB of memory per vCPU but lacks local storage, relying instead on network-attached options with a 10 Gbps baseline bandwidth. The processor supports AVX-512 and cryptographic extensions, contributing to strong single-core and multi-core Geekbench scores that rank in the top 25%. While multi-core stress-ng and Passmark CPU scores sit in the middle 50%, memory and encryption performance remain strong. This resource profile is suited for general-purpose workloads such as web serving, database operations, and software compilation where local high-speed storage is not a primary requirement.

      Workload Profiles

      1.5Score
      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.Partial coverage: missing component benchmark(s): Memory bandwidth (read, 16 MB ~ L3).
