Intel’s Entire 10th Gen Comet Lake Desktop CPU Lineup Leaked + Intel 400-Series Platform & LGA 1200 Socket Detailed


  • Intel’s Entire 10th Gen Comet Lake Desktop CPU Lineup Leaked + Intel 400-Series Platform & LGA 1200 Socket Detailed





    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. 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. 


    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. 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 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. 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 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. Intel plans to have several chipsets deployed in the 400-series family. There would obviously be Z490 which will target the 'K' unlocked SKUs. 




    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.

    Again, as with all leaks/rumors, to avoid disappointment - maintain a skeptical outlook until the information within can be confirmed by more sources. However, at least with this one, there seems to be a decent amount of slides present. While this doesn't eliminate it from being completely faultless, it at least gives more conviction to the source material. Funnily enough, the addition of all SKUs now having HT (except Celeron) is interesting to say the least. Being that Ryzen has been offering this since launch, with Intel's reluctance to follow suit. This is obviously a great move by Intel, and IMO, displays Intel being realistic about the current state of competition within the CPU space. I think seeing the pricing though will determine exactly how serious Intel actually is.

Please follow the source link to check out all of those; as I felt uploading all of them here would be a bit too much with the amount of slides I have already uploaded.
