Recent entries in the Geekbench database shed light on the specifications of Intel's upcoming 5th generation Xeon Scalable processors, known under the codename Emerald Rapids. The data reveals information on various product tiers within the new lineup, including processors with up to 48 cores.
The Xeon Platinum 8558P is highlighted as a 48-core and 96-thread processor, with a base clock of 2.7 GHz and a potential to reach 4.0 GHz during boost. This CPU is equipped with a 16 MB L3 cache and an extensive 192 MB L2 cache, accumulating a substantial total cache of 260 MB. It also features an eight-channel DDR5 integrated memory controller capable of speeds up to 4800 MT/s and is designed to operate at a thermal design power (TDP) of 350 Watts.
Another model, the Xeon Platinum 8551C, mirrors the 48-core and 96-thread configuration and shares the 260 MB combined cache size. This variant, however, begins with a higher base frequency of 2.9 GHz, though additional details on its boost frequency and memory controller specifics are yet to be disclosed. Comparison with the previously detailed 48-core Xeon 8558U, which contains a larger cache composition of 96 MB L2 cache and 260 MB L3 cache, reveals Intel's differentiated approach to processor segmentation. Such differentiation now takes into account not only core counts, frequencies, and power consumption but also cache size variations between models.
