Comet Lake specs were leaked. Intel has not been very successful at trying to keep new products under wraps.

Comet Lake-S which is the official codename for the mainstream desktop family is based on a refined 14nm++ process node. The family would be replacing Intel’s 9th Gen Core CPU family which recently saw the launch of the flagship Core i9-9900KS.

  • Up To 10 processor cores for enhanced performance
  • Up To 30 PCH-H High-Speed I/O lanes for port flexibility
  • Up To 40 PCIe 3.0 Lanes (16 CPU, up to 24 PCH)

The Intel 10th Generation Comet Lake-S family would initially launch with 9 SKUs with more to come later. They would be segmented in the Xeon W, Core i9, Core i7, Core i5, Core i3, Pentium and Celeron parts.


Intel is introducing a new chipset early next year. The LGA 1200 socket has the same dimensions as the LGA 1151 socket (37.5mm x 37.5mm), the socket keying has shifted to the left side and Comet Lake is no longer electrically or mechanically compatible with Coffee Lake motherboards.

  • Comet Lake will transition to a higher pin-count package
  • Comet Lake LGA will not have backward compatibility with legacy platforms
  • No changes to ILM dimensions or thermal solution retention
  • Comet Lake LGA improves power delivery and support for future incremental I/O features
  • Pin 1 orientation remains the same, but socket keying has shifted left

Comet lake will provide the community with new motherboards and processors for a new build or overhaul. Comet lake will continue to use DDR4. The W480 and Z490 will be the main gaming platforms. The Q470 is aimed at corporate users. The low end H410 is apparently not pin compatible and should be avoided.
