Breaking News: Intel Xeon 8558U CPU with 48 Cores Revealed
There are hints of Intel’s future Xeon Platinum 8558U “Emerald Rapids” CPU, which has 48 cores and a large cache
The Xeon Platinum 8558U chip has 77% more cache than its 4th generation Sapphire Rapids predecessor, the Intel Emerald Rapids “5th Gen Xeon” CPUs provide a significant increase in cache
With 96 MB of L2 cache, that comes to 356 MB total, which is 77% more than the Sapphire Rapids chips, which in the identical 48 core configurations give up to 201 MB (105 MB L3 + 96 MB L2) of cache
The specs of the 8558U Xeon include 96 threads, a base clock of 2.0 GHz, and a total of 48 cores based on the Raptor Cove P-Core architecture
The Intel Xeon Platinum 8558U “Emerald Rapids” has a large 260 MB pool of L3 cache, and each die cluster has two MB of L2 cache spread over 48 MB pools
Similar cache count improvements over their predecessors are also seen in the recently leaked Xeon Platinum 8592+ and Xeon Platinum 8580 “Emerald Rapids” CPUs, with the top chip providing 448 MB of cache
