CPU and System Topology
Server Description
A dedicated multi-core compute instance featuring a highly streamlined memory profile for parallelized, compute-bound workloads.
Alibaba Cloud ecs.ic5.4xlarge is an x86_64 compute-focused server instance powered by an Intel Xeon 8163 processor running at 2.5 GHz. It features 16 dedicated vCPUs across 8 physical cores, 16.0 GB of memory, and a 5 Gbps baseline network speed, with no local storage or GPU accelerators. The instance exhibits a distinct performance profile: single-core benchmarks and single-threaded compression tasks score in the bottom 25% and 10% respectively, while multi-threaded benchmarks, memory bandwidth, and static web serving throughput consistently reach average tiers. With a low memory-to-vCPU ratio of 1.0 GB per core, this instance offers a cost-efficient option for parallelized, compute-bound workloads that do not demand large memory footprints. It is best suited for multi-threaded software compilation, static web serving, and basic database operations.
