The announced processors combine from eight to 86 computing cores with multithreading support. Depending on the modification, the chips can be installed in single-, dual-, quad- and eight-socket servers. The TDP indicator varies from 150 to 350 W. For comparison: Xeon 6900P solutions have up to 128 cores and have a TDP of up to 500 W, but can only be used in single- and dual-socket machines.
The Xeon 6700P and Xeon 6500P chips support eight channels of DDR5-6400 or MRDIMM-8000 memory (not all models). The L3 cache size varies from 48 to 336 MB. Support for 88 PCIe 5.0 lanes is implemented (136 lanes for modifications for single-socket servers), as well as up to four UPI 2.0 lanes. The maximum clock frequency in turbo mode is 4.3 GHz (see specifications below). AVX-512 (Advanced Vector Extensions), AMX (Advanced Matrix Extensions), etc. are implemented.
The flagship Xeon 6787P model has 86 cores with a frequency of up to 3.8 GHz and a TDP of 350 W: the chip is priced at $10,400. In the eight-socket server segment, the most powerful chip is the Xeon 6788P model with similar characteristics, which costs $19,000. The most affordable of the announced products are the eight-core Xeon 6507P (up to 4.3 GHz, 150 W) for $765 and the 12-core Xeon 6505P (4.1 GHz, 150 W) for $563. The series of chips for single-socket servers is headed by the Xeon 6781P variant with 80 cores, a frequency of up to 3.8 GHz and a TDP of 350 W: such a chip will cost $8,960.
