CPU and System Topology
Server Description
A dedicated compute-optimized instance featuring thirty-two physical AMD EPYC cores and a balanced memory architecture for processing-heavy workloads.
Alibaba Cloud ecs.c7a.8xlarge is an x86_64 compute-optimized instance featuring 32 dedicated physical cores and 32 vCPUs powered by an AMD EPYC 7T83 processor at 2.55 GHz. It is equipped with 64.0 GB of RAM, providing 2.0 GB of memory per core, and operates on the KVM hypervisor with an 8 Gbps baseline network bandwidth. The instance does not include local storage or GPU hardware. Performance benchmarks indicate strong single-core CPU execution and high PassMark memory scores, though multi-core operations and web serving throughput remain average. A key tradeoff is its weak large-block memory write bandwidth. This instance is designed for compute-heavy workloads such as software compilation, text processing, and medium-scale database operations where dedicated CPU resources are required without the need for high memory-to-CPU ratios.
