The Geekbench database of benchmark submissions is revealing new information about Intel's upcoming 5th generation Xeon Scalable processors, codenamed Emerald Rapids. Previously, we reported on the leak of the potentially high-end 64-core Xeon 8592+ Platinum and a 48-core Xeon 8558U processor. However, today we have details about lower-stack SKUs that have up to 48 cores each.
The first SKU is the Xeon Platinum 8558P, which is a 48-core, 96-thread CPU with a base frequency of 2.7 GHz and a boost frequency of 4.0 GHz. It has 16 MB of L3 cache and an additional 192 MB of L2 cache, resulting in a total cache memory of 260 MB. The Xeon Platinum 8558P's integrated memory controller (IMC) supports eight-channel DDR5 running at 4800 MT/s, and the CPU has a TDP of 350 Watts.
The other SKU listed is the Xeon Platinum 8551C, also a 48-core, 96-thread model with the same 260 MB cache configuration. However, this SKU has a higher base frequency of 2.9 GHz, with an unknown boost speed and IMC configuration.
An interesting point to note about these 48C/96T SKUs is that they have less cache compared to the previously leaked 48-core Xeon 8558U processor, which had 96 MB of L2 cache and 260 MB of L3 cache, resulting in a total of 356 MB of cache (including L1D and L1I). Intel's segmentation of its Xeon processors will be based not only on core count, frequency, and TDP but also on CPU cache sizes.
