CPU and System Topology
Server Description
A balanced general-purpose instance featuring dedicated AMD EPYC processing cores and strong single-core performance for standard enterprise workloads.
Alibaba Cloud ecs.g8a.4xlarge is a general-purpose instance featuring 16 dedicated vCPUs and 16 physical cores powered by an AMD EPYC 9T24 processor running at 2.7 GHz. Built on the x86_64 architecture and KVM hypervisor, it is configured with 64.0 GB of system memory, yielding a balanced 4.0 GB per core. The instance does not include local storage or GPU hardware, and it delivers a baseline network bandwidth of 7 Gbps. Benchmark data shows strong single-core CPU and text processing performance, while multi-core operations, cryptography, and database tasks perform in the average tier. A key tradeoff is its weak uncached large-block memory read bandwidth. This instance is suited for general-purpose workloads, including web serving, software compilation, and standard database operations that require dedicated compute resources without local storage dependencies.
