Intel Xeon Platinum “Emerald Rapids” 48-Core CPU SKUs 8558P and 8551C Leaked

Further information about Intel’s upcoming 5th generation Xeon Scalable processors, codenamed Emerald Rapids, is emerging from the benchmark submission database Geekbench. We previously discussed the leak of the 48-core Xeon 8558U and the potentially top-tier 64-core Xeon 8592+ Platinum processors. On the other hand, information regarding lower-stack SKUs with up to 48 cores each is becoming available. The Xeon Platinum 8558P, a 48-core, 96-threaded CPU with a base frequency of 2.7 GHz and a boost frequency of 4.0 GHz, is the first in line. It has 192 MB of L2 cache and 16 MB of L3 cache, for a total of 260 MB of cache memory. With a TDP of 350 Watts, the Xeon Platinum 8558P CPU supports eight channels of DDR5 operating at 4800 MT/s through its integrated memory controller (IMC).

The Xeon Platinum 8551C, a 48-core, 96-thread model with the same 260 MB cache configuration, was the other SKU that was also listed. This SKU, on the other hand, has an unknown IMC configuration, an unknown boost speed, and a higher base frequency of 2.9 GHz. It’s interesting to note that these 48C/96T SKUs have less cache than the previously leaked 48-core Xeon 8558U processor, which had 356 MB of cache total (which includes L1D and L1I as well). That processor had 96 MB of L2 cache and 260 MB of L3 cache. For its Xeon processors, Intel is segmenting the chips based on CPU cache sizes in addition to core count, frequency, and TDP.
