Google Cloud C4D Performance Benchmarks Show 39% Improvement with Turin

Back in April at Google Cloud Next was the introduction of the new C4D family of VMs powered by AMD EPYC 9005 "Turin" processors. Back on launch day I looked at the C3D vs. C4D performance at some of the smaller, more common VM sizes. In today's article is a look at the top-end performance of the C4D family with 384 vCPUs. For those wondering about the compute potential of the c4d-standard-384, here are some benchmarks of this 192-core / 384-thread EPYC Turin configuration compared to the prior C3D AMD EPYC Genoa based instance that topped out at 360 vCPUs.

Like the smaller VM sizes, the c4d-standard-384 still relies on the AMD EPYC 9B45 processor custom SKU. The c4d-standard-384 provides 192 cores and 384 threads on Zen 5 compared to the top-end c3d-standard-360 with 180 cores / 360 threads of Zen 4. The c4d-standard-384 is allocated 1488GB of system memory while the c3d-standard-360 has 1440GB.

Both the c3d-standard-360 and c4d-standard-384 instances were tested with Ubuntu 24.04 LTS on the Linux 6.8 kernel and GCC 13.3 compiler, among the other OS defaults.

These benchmarks are primarily being done for reference purposes across a variety of primarily HPC and AI workloads. Thanks to Google for providing access to the C3D/C4D VMs for free in order to be able to provide these cloud performance benchmarks.
