CPU and System Topology
Server Description
A dedicated 32-core Arm-based compute instance delivering strong multi-threaded decompression and database performance with a balanced memory profile.
Alibaba Cloud ecs.c8y.8xlarge is an arm64 compute-optimized server powered by the 2.75 GHz Alibaba Yitian 710 processor. It features 32 dedicated physical cores with a 1:1 thread-to-core ratio, 64.0 GB of RAM, and a 16 Gbps baseline network bandwidth, with no local storage or GPU hardware. In benchmark testing, the instance demonstrates strong performance in multi-threaded bzip3 decompression and database operations, both ranking in the top 25%. Other metrics, such as stress-ng CPU performance and Redis SET operations, align with average tiers. The custom Arm architecture provides high physical core density, though it lacks x86-specific vector extensions like AVX. This instance is suited for multi-threaded decompression, database operations, static web serving, and moderate-scale machine learning inference.
