CPU and System Topology
Server Description
A dedicated AMD EPYC compute-optimized instance with an efficient vCPU-to-RAM ratio for web serving and key-value database workloads.
Alibaba Cloud ecs.c6a.2xlarge is an x86_64 compute-optimized instance featuring 8 dedicated vCPUs and 8 physical cores powered by an AMD EPYC 7H12 processor running at 2.6 GHz. It is configured with 16.0 GB of RAM (2.0 GB per core), 2 Gbps baseline network bandwidth, and no local storage or GPU hardware. Performance benchmarks indicate average capabilities across most standard operations, with a Geekbench multi-core score of 5025.0 and a Passmark CPU score of 10249.39. While raw compute benchmarks like stress-ng fall into lower percentiles, the instance maintains average performance in memory bandwidth for small cached blocks and database operations. This instance is qualitatively cost-effective for dedicated compute workloads with moderate memory requirements, making it suitable for static web serving, Redis key-value stores, and light database operations.
