'''Comet Lake''' ('''CML''') is a planned [[microarchitecture]] designed by [[Intel]] as a successor to {{\\|Coffee Lake}} and {{\\|Whiskey Lake}} for desktops, high-performance mobile devices, and ultra-low power mobile devices.
+
'''Comet Lake''' ('''CML''') is [[Intel]]'s successor to {{\\|Coffee Lake}}, an enhanced [[14 nm process]] [[microarchitecture]] for mainstream desktops and mobile devices.
  
 +
For desktop and mobile, Comet Lake is branded as 10th Generation Intel {{intel|Core i3}}, {{intel|Core i5}}, {{intel|Core i7}}, and {{intel|Core i9}} processors.

Comet Lake is expected to be released in mid-2019.
+
Comet Lake processors were introduced in a number of phases. Initial mobile processors were launched on August 21, 2019. Intel followed up with the remaining desktop parts on April 30, 2020. Enterprise and vPro models were followed on May 13, 2020.
 +
 
 +
== Compatibility ==
 +
There are no official drivers by Intel for [[Windows 7]] or [[Windows 8]]. [[Microsoft]] announced that only [[Windows 10]] will have support for Kaby Lake. [[Linux]] added initial support for Kaby Lake starting with Linux Kernel 4.5.

Succession

Comet Lake (CML) is Intel's successor to Coffee Lake, an enhanced 14 nm process microarchitecture for mainstream desktops and mobile devices.

For desktop and mobile, Comet Lake is branded as 10th Generation Intel Core i3, Core i5, Core i7, and Core i9 processors.

Codenames[edit]

Core Abbrev Description Graphics Target
Comet Lake S CML-S Mainstream performance GT2 Desktop performance to value, AiOs, and minis
Comet Lake U CML-U Ultra-low power GT2 Light notebooks, portable All-in-Ones (AiOs), Minis, and conference room

Brands[edit]

Intel has released Comet Lake under 4 main brand families:

Logo Family General Description Differentiating Features
Cores HT AVX AVX2 TBT ECC

core i5 logo (2015).png Core i5 Mid-range Performance Hexa ✔ ✔ ✔ ✔ ✘
core i7 logo (2015).png Core i7 High-end Performance Octa ✔ ✔ ✔ ✔ ✘
50px Core i9 Ultra Performance Deca ✔ ✔ ✔ ✔ ✘

Release Dates[edit]

Comet Lake processors were introduced in a number of phases. Initial mobile processors were launched on August 21, 2019. Intel followed up with the remaining desktop parts on April 30, 2020. Enterprise and vPro models were followed on May 13, 2020.

Compatibility[edit]

There are no official drivers by Intel for Windows 7 or Windows 8. Microsoft announced that only Windows 10 will have support for Kaby Lake. Linux added initial support for Kaby Lake starting with Linux Kernel 4.5.

Vendor OS Version Notes
Microsoft Windows Windows 7 No Support
Windows 8 No Support
Windows 10 Support
Windows 11 Support
Linux Linux Kernel 4.5 Initial Support (Fedora 24, Yocto v2.2, ..)
Google Chromium Chromium Support
Wind River VxWorks VxWorks 7 Support

Compiler support[edit]

Architecture[edit]

Key changes from Coffee Lake[edit]

  • Enhanced "14nm++" process results in higher turbo frequencies
  • System Architecture
  • Memory
    • Faster memory for mainstream desktops (i.e., Comet Lake S) DDR4-2933 (from DDR4-2666)
  • Packaging

This list is incomplete; you can help by expanding it.

        • Read: 32 B/cycle (@ ring clock)
        • Write: 32 B/cycle (@ ring clock)
      • 42 cycles for fastest load-to-use
    • Side Cache:
      • 64 MiB & 128 MiB eDRAM
      • Per package
      • Only on the Iris Pro GPUs
      • Read: 32 B/cycle (@ eDRAM clock)

      • 42 cycles + 51 ns latency

Coffee Lake TLB consists of dedicated L1 TLB for instruction cache (ITLB) and another one for data cache (DTLB). Additionally there is a unified L2 TLB (STLB).

  • TLBs:
    • ITLB
      • 4 KiB page translations:
        • 128 entries; 8-way set associative
        • dynamic partitioning
      • 2 MiB / 4 MiB page translations:
        • 8 entries per thread; fully associative
        • Duplicated for each thread
    • DTLB
      • 4 KiB page translations:
        • 64 entries; 4-way set associative
        • fixed partition
      • 2 MiB / 4 MiB page translations:
        • 32 entries; 4-way set associative
        • fixed partition
      • 1G page translations:
        • 4 entries; 4-way set associative
        • fixed partition
    • STLB
      • 4 KiB + 2 MiB page translations:
        • 1536 entries; 12-way set associative
        • fixed partition
      • 1 GiB page translations:
        • 16 entries; 4-way set associative
        • fixed partition


  • Note: STLB is incorrectly reported as "6-way" by CPUID leaf 2 (EAX=02H). Coffee Lake erratum CFL084 recommends software to simply ignore that value.
