But, of course, not all server workloads are memory intensive where it would help much for populating all 12 memory channels, especially if operating on a tight budget.

For a number of the workloads, running at 10 memory channels would provide slightly better value or if looking to stave off some of the DDR5 server memory costs to a later quarter.

For some of the common Intel libraries used in creator software like oneAPI's OpenVKL and Open Image Denoise hadn't seen much of a benefit beyond 8 channels, at least for the benchmark configurations tested.
