We know that Intel is readying its 6th installment of their 14nm mainstream desktop family known as Comet Lake which arrives next year. There has been much that we have talked about but today, we have exclusive information covering the entire 10th Generation desktop CPU family, ranging from each specific SKU to the platform itself.

Intel 10th Gen Comet Lake Desktop CPU Lineup Leaked - Up To 10 Cores, 20 Threads, 80W TDP on Core i9-10900, New 400-Series Chipsets With LGA 1200 Socket

So let's start off with the details, the Intel 10th Generation desktop processor family will be known as Comet Lake. 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 (you can read our complete review of the CPU here). Since 10nm production is still not up to par for mass deployment, Intel will be skipping it however as of recently, Intel claims to see the release of 10nm desktop processors in 2020.

Following are some of the main platform features of the 10th Generation Comet Lake-S family:

  • 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)
  • Media & Display features for premium 4K content support
  • Integrated + Discrete Intel Wireless-AC (Wi-Fi/BT CNVi) Support
  • Intel Wi-Fi 6 (Gig+) Support
  • Enhanced Core and memory overclock
  • Integrated USB 3.2 Gen 2x1 (10 Gb/s) support
  • Intel Rapid Storage Technology (Intel RST)
  • Programmable (Open FW SDK) Quad-Core Audio DSP
  • C10 & S0ix Support for Modern Standby

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. Surprisingly, Intel would have two different chip layouts for their Comet Lake family. The 10 core and 8 core variants would be based on the Comet Lake-S 10+2 wafer while the rest of the parts would be based on the Comet Lake-S 6+2 wafer.

According to the Intel slide, the 10th Generation Comet Lake family would deliver an 18% performance improvement in multi-threaded compute workloads compared to 9th Generation processors and an 8% generational improvement over 9th Gen parts in general windows workloads.

The flagship variant of the 10th Generation Core family would be the Intel Core i9-10900 which would feature 10 cores and 20 threads. This chip would be clocked at 3.0 GHz base and 5.1 GHz boost clocks along with 20 MB of cache. The chip would feature a 65W design and the unlocked variant which hasn't been listed yet would offer higher clocks, unlocked design along with a much higher TDP. The Xeon variant comes with a higher TDP of 80W but has a higher base frequency of 3.1 GHz while boost clocks stick to 5.1 GHz like the Core i9-10900. The entire lineup can be seen in the table below:

Even the regular Core i7 part with 8 cores and 16 threads has a maximum frequency of 4.8 GHz at 65W TDP. This means that the 'K' series part would have a boost frequency of 5.0 GHz (single-core) which is pretty good if priced right. The 8 core and 16 thread parts could end up being priced around the $350 US range which has been the price segment for Core i7 processors for a while now and the 8 core Ryzen parts may be getting some heated battle in this market.

As expected before, all 10th Generation Core SKUs would feature multi-threading support. The Core i9 lineup would get 10 cores and 20 threads, the Core i7 lineup would get 8 cores and 16 threads, the Core i5 lineup would get 6 cores and 12 threads while the Core i3 lineup would get 4 cores and 8 threads. The Pentium lineup would also get multi-threading support with 2 cores & 4 threads. This leaves the Celeron lineup out which won't receive multi-threading support and would be limited to 2 cores and 2 threads. It can be seen that neither of the 'K' unlocked SKUs has been mentioned in the list which means that they would be released later on.

Do note that the TDP for 'K' unlocked SKUs would be higher than the non-K models and they would be featuring support on the Z490 chipset while the more mainstream-aimed non-K chips would be aimed at the W480, Q470 and H410 chipset based motherboards.

Intel 400-Series Platform & LGA 1200 Socket Support

This brings us to the next topic which is related to the 400-series platform and the new LGA socket. It is now confirmed that Intel is indeed moving to a new socket with their 400-series motherboards that will be introduced next year too. While 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. Some details of the new LGA 1200 package and socket for Comet Lake:

  • 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

The good thing is that your existing coolers would still be compatible with the LGA 1200 socket so that's one hardware change you shouldn't be worrying about. The Comet Lake-S family will retain support for DDR4-2666 memory UDIMM and support up to 32 GB capacity DIMMs per channel.

Intel plans to have several chipsets deployed in the 400-series family. There would obviously be Z490 which will target the 'K' unlocked SKUs I mentioned above but aside from that, we are looking at the W480 (Entry Workstation), Q470 (Corporate with Intel vPro) and H410 (Value) chipsets. These would target more corporate and entry tier users. Also interesting to note is that H410 is not pin-compatible with W480 and Q470 chipsets which reveals a very cut down design for the entry-level chip.

In terms of chipset features, W480 would be the most feature-rich of the three chipsets that are mentioned here. Z490 would be the most appealing for the enthusiast and gaming audience but let's take a look at the mainstream chipsets. The W480 chipset would offer a  total of 46 high-speed IO lanes and a total of 40 PCIe Gen 3.0 lanes. The CPUs would retain 16 lanes with the chipset offering up to 24 PCIe 3.0 lanes.

There would be support for up to 8 SATA III ports, 8 USB 3.2 Gen 2 ports or 10 USB 3.2 Gen 1 ports, 14 USB 3.2 Gen ports and Intel RST. Neither of the three chipsets would feature overclock support since that is restricted to the Z490 chipset but we will get more information on overclocking later on from Intel themselves.
