Intel 5th Gen Xeon Performance Benchmarks With DDR5-4800 vs. DDR5-5600

As more DDR5-5600 server memory modules come to market and ultimately reaching the point of offering tighter timings, the results may evolve moving forward. For now though it ultimately depends upon how memory sensitive the workloads you are most often running to whether DDR5-5600 is necessarily worthwhile compared to the more common -- and less expensive -- DDR5-4800 server memory. If you are upgrading an existing Sapphire Rapids server, as you can see from these results in many HPC and server workloads you can enjoy great performance on Emerald Rapids even with DDR5-4800 memory.

Across more than three dozen benchmarks run, there was less than a 2% improvement overall for these HPC/server workloads but again with the memory tested it meant going from DDR5-4800 @ CL40 to DDR5-5600 @ CL46. With the memory at hand the DDR5-5600 memory was also around $95 USD more expensive per module. In any event hopefully you found these numbers useful if trying to decide between these server memory options with Intel 5th Gen Xeon Scalable. Either with DDR5-4800 or DDR5-5600, Intel Emerald Rapids server processors are very capable in up to 64 cores and especially for AI / AMX workloads or if leveraging software that can make use of their accelerator IP.

Thanks again to Intel for providing the Xeon Platinum 8592+ review samples as well as the memory used for testing.
