CPU and System Topology
Server Description
A balanced general-purpose instance featuring dedicated Intel Xeon processing and steady memory bandwidth for standard enterprise workloads.
Alibaba Cloud ecs.u1-c1m4.8xlarge is an x86_64 general-purpose instance featuring 32 dedicated Intel Xeon physical cores operating at 2.5 GHz and 128.0 GB of RAM. Lacking local storage and GPU hardware, the instance relies on network-attached storage and features a 10 Gbps baseline network bandwidth. Performance benchmarks place this instance in the average tier, with a Geekbench multi-core score of 12613.0 and a stress-ng multi-core score of 30903.16. It exhibits strong performance in small-model LLM text generation, achieving 297.4 tokens per second. The lack of local storage is a key tradeoff, but its dedicated CPU allocation and balanced resource ratio provide qualitative cost efficiency for non-storage-intensive workloads. It is best suited for static web serving, Redis caching, database operations, and general-purpose enterprise applications.
