Comet Lake (CML) Architecture: Coffee-Lake Refresh Refresh aka two more cores

Comet Lake should be similar to the Whiskey Lake (WHL-U in the picture).
Comet Lake should be similar to the Whiskey Lake (WHL-U in the picture).

Currently we only know that Comet Lake will be another refresh of the Skylake architecture. The new feature of Comet Lake are additional cores in the top models. Three series are currently known:

  • Comet Lake Y: Successor of Amber Lake Y and intended for small tablets and fanless laptops. As Ice Lake Y, Comet Lake Y should also offer now up to 4 cores (2 more than Amber Lake Y).
  • Comet Lake U: 15 Watt and with up to 6 cores.
  • Comet Lake S: Mainstream Desktop CPUs with up to 10 cores and a TDP of 125 Watt. Rumored to use a new socket.

Old CPU-Architecture

Die microarchitecture of the processor cores is still based on the old Skylake CPUs that was already refreshed with Kaby Lake and Coffee Lake. The differences to Coffee Lake should be minimal. Thanks to the 14nm++ process, the Comet Lake CPUs should hit high Turbo frequencies and therefore good performance results.

Integrated graphics card - still Gen 9.5

The integrated graphics card is still the old Gen 9 / 9.5 and should even bear the same name as in Whiskey Lake. See e.g. our GPU page of the Intel UHD graphics 620.

Additional Features in the SoC

Similar to the Whiskey Lake processors, Comet Lake also includes some additional features. The integrated dual channel memory controller now supports DDR4-2666 (up from DDR4-2400 in Whiskey Lake) and still the slower but more power efficient LPDDR3-2133 RAM. The video engine should be untouched and still support VP.9, H.265 and H.264 video en- and decode.
