Xeon 6: Intel's Granite Rapids now also with 16 to 86 cores for LGA4710
Intel is launching a whole range of new server processors. On request, these are also available with a thick Ethernet connection directly on board.

Intel is announcing a total of 51 processors for servers and workstations. New are 42 Xeon 6700P and 6500P (codenamed Granite Rapids). Intel is also adding another model to its existing 6900P series. The eight Xeon 6300P suggest new technology with their new name, but are just another Raptor Lake refresh for the old LGA1700 platform. They clock slightly higher than the previous Xeon E-2400.
The previous Xeon 6900P use Intel's largest CPU socket LGA7529. This is necessary because the manufacturer combines three CPU chips with two I/O chips for up to 128 performance cores. This is followed by the types for the "more normal" LGA4710 platform with three different core configurations: XCC (Extreme Core Count) uses two CPU chiplets for up to 86 cores, HCC (High Core Count) uses one CPU chiplet for 48 cores and LCC (Low Core Count) gets a separate die with 16 cores.
All variants share the same two I/O chiplets. The LGA4710 platform makes do with eight instead of twelve DDR5-6400 memory channels. Alternatively, the previously introduced Xeon 6700E with up to 144 efficiency cores run on LGA4710 mainboards. 88 PCI Express 5.0 lanes are available for expansion cards and additional chips.

12 to 86 P cores
Intel divides the Xeon 6700P and 6500P into the three series Performance, Mainline and Scalable, from the Xeon 6505P to the 6788P. "Performance" does not directly stand for high performance – the series scales from eight to 86 CPU cores. However, all integrated accelerators are active, i.e. four Data Streaming Accelerators (DSA), In-Memory Analytics Accelerators (IAA), Quick Assist Technology units (QAT) and Dynamic Load Balancers (DLB).
They can also store 2048 cryptographic keys in their sealed security enclave (TDX, formerly known as SGX). Five models support multiplexed-rank DIMMs (MRDIMMs or MCR-DIMMs) with DDR5-8000 speed. Such latches use buffer chips. All performance variants fit into one- and two-socket mainboards.
The mainline and scalable types cannot handle MRDIMMs, store a maximum of 1024 TDX keys and in some cases only have half as many of the accelerators mentioned above. Seven of the processors can be scaled up considerably in 8-socket mainboards.
Six other models ending with the number 1 are intended for cheaper single-socket mainboards. The 80- and 64-core 6781P and 6751P support MRDIMMs. In the case of the Xeon 6900P, Intel is pushing the 6944P with 72 cores. It lacks the integrated accelerators and MRDIMM support.

)Edge Xeons and new Ethernet controllers
13 other processors use a separate I/O die for edge servers. Intel integrates the logic for Ethernet with speeds of 100 and 200 Gbit/s into this. They use 12 to 42 CPU cores – even faster variants are to follow by the end of the year.

Two new Ethernet controllers also come from the network division: the E830 for two 25 Gbit/s on 16 PCIe 4.0 lanes primarily for servers and the E610 for up to two 10 Gbit/s on four PCIe 4.0 lanes. The latter would also be something for workstations or as an alternative to Realtek and Marvell/Aquantia controllers on more expensive desktop mainboards.
Last but not least, there is news about the Xeon 6900E aka Sierra Forest AP with up to 288 efficiency cores. Intel does not intend to bring these processors to the market on a regular basis, but will sell them directly to hyperscale partners in the near future.
