CPU and System Topology
Server Description
An AMD-powered virtual machine offering a high memory-to-core ratio and strong single-core performance for memory-bound workloads.
Microsoft Azure EC4as_cc_v5 is a memory-optimized virtual machine from the ECACCV5 family, configured with 4 dedicated vCPUs and 32.0 GB of RAM. Powered by an AMD EPYC 7763 processor running at 3.525 GHz, this x86_64 instance features 2 physical cores with hyper-threading and a 32 MB L3 cache. It lacks local storage and GPUs but supports Premium Storage for remote disks. Performance benchmarks indicate strong single-core CPU execution, though multi-core scaling and memory write bandwidth are relatively weak. With a high memory-to-vCPU ratio of 8.0 GB per core, this instance is best suited for memory-intensive workloads, small databases, and caching applications that require a larger memory footprint relative to compute power, rather than highly parallelized or high-throughput web serving tasks.
