CPU and System Topology
Server Description
An arm64 compute-optimized server featuring dedicated ARMv9 cores and top-tier memory bandwidth for data-intensive workloads.
Amazon Web Services c8g.4xlarge is a compute-optimized instance featuring 16 dedicated arm64 physical cores on the ARMv9 Neoverse-V2 architecture running at 2.8 GHz. It is configured with 32.0 GB of memory, providing 2.0 GB per core, and operates on the Nitro hypervisor with an 8 Gbps baseline network bandwidth. The instance does not include local storage or GPUs. Benchmarks highlight top-tier memory performance, with a Passmark memory score in the top 10% and strong large-block memory bandwidth reads of 302.31 GB/sec. While CPU performance in stress-ng and Geekbench is average, multi-threaded bzip3 decompression and database operations perform strongly. This server is highly efficient for memory-bandwidth-sensitive compute tasks, multi-threaded decompression, database operations, and static web serving.
