CPU and System Topology
Server Description
A dedicated eight-core x86_64 server with low memory density, designed for lightweight compute tasks and basic utility workloads.
Alibaba Cloud ecs.u0.c1m1.2xlarge is an x86_64 server instance powered by an Intel Xeon 8163 processor operating at 2.5 GHz. It provides 8 dedicated physical cores and 8 vCPUs, paired with 8.0 GB of system memory, resulting in a low 1.0 GB of RAM per core. The instance lacks local storage and GPU accelerators, relying on a baseline network bandwidth of 2 Gbps. Benchmark data shows weak to poor performance across most CPU and memory tests, though it achieves average marks in Passmark CPU and small-model LLM inference. Due to the low memory-to-CPU ratio and modest processing speeds, this instance is best suited for lightweight compute workloads, basic web serving, and development environments that do not require high memory capacity or local storage.
