CPU and System Topology
Server Description
A compute-optimized virtual server featuring dedicated AMD EPYC cores and NVMe storage for CPU-intensive, low-memory workloads.
The OVHcloud c3-8 is a compute-optimized virtual server powered by an x86_64 AMD EPYC processor running at 2.3 GHz on a KVM hypervisor. It features 4 dedicated physical cores with hyperthreading disabled, 8.0 GB of RAM, and a 100 GB NVMe SSD. While stress-ng benchmarks show strong single-core CPU performance, its memory subsystem and static web serving throughput are relatively weak, placing in the bottom 25% of benchmarks. The server lacks GPU acceleration and has a baseline network bandwidth of 0 Gbps. Given its 1:2 vCPU-to-RAM ratio and dedicated CPU allocation, the c3-8 is qualitatively cost-effective for CPU-bound workloads that require dedicated execution threads but have modest memory requirements, such as lightweight software compilation, single-threaded processing, and basic application hosting.
