CPU and System Topology
Server Description
A balanced general-purpose virtual server with dedicated Intel Xeon processors, optimized for multi-threaded workloads and stable resource allocation.
Alibaba Cloud ecs.g5.4xlarge is a general-purpose instance featuring 16 dedicated vCPUs and 64.0 GB of RAM, powered by an Intel Xeon 8163 processor at 2.5 GHz. Built on the x86_64 architecture under the KVM hypervisor, this instance does not include local storage or GPU accelerators, relying instead on network-attached storage and a 5 Gbps baseline network bandwidth. Performance benchmarks reveal a contrast between single-core and multi-core capabilities; single-threaded tasks, such as gzip compression and single-core stress-ng tests, fall into the lower performance tiers, whereas multi-core benchmarks, memory bandwidth, and database operations perform at average levels. Consequently, this instance is suited for balanced multi-threaded workloads, including static web serving, software compilation, and database operations, where dedicated CPU allocation provides resource stability without requiring extreme single-core performance.
