Intel has announced the next family of Xeon processors that it plans to ship in the first half of next year. The new parts represent a substantial upgrade over current Xeon chips, with up to 48 cores and 12 DDR4 memory channels per socket, supporting up to two sockets.

These processors will likely be the top-end Cascade Lake processors; Intel is labelling them "Cascade Lake Advanced Performance," with a higher level of performance than the Xeon Scalable Processors (SP) below them. The current Xeon SP chips use a monolithic die, with up to 28 cores and 56 threads. Cascade Lake AP will instead be a multi-chip processor with multiple dies contained with in a single package. AMD is using a similar approach for its comparable products; the Epyc processors use four dies in each package, with each die having 8 cores.
