Intel 10th Gen Comet Lake Leak: Specs for F-Series Desktop CPUs Posted

Uruguayan media outlet Informática Cero has published alleged specifications for Intel's looming 10th Generation Comet Lake F-series desktop processors. The PowerPoint slide appears to be part of a Comet Lake presentation that leaked back in December.

Intel first introduced the F-series concept with its 9th Generation Coffee Lake processors. Those F-series chips have the same silicon as their non-F counterparts but lack integrated graphics, providing Intel a way to salvage silicon that failed to meet graphics standards. If Informática Cero's slide is legitimate, Intel will seemingly follow this same game plan for Comet Lake.

It appears that Intel could launch up to three F-series and KF-series Comet Lake processors. The slide names a Core i9-10900KF, Core i7-10700KF and Core i5-10600KF, as well as their respective locked variants, (which can't be overclocked), the Core i9-10900F, Core i7-10700F and Core i5-10600F.

The KF-series chips reportedly adhere to a 125W TDP (thermal design power), with the F-series chips confined to 65W. Only the i9 parts benefit from Intel's Thermal Velocity Boost (TVB) technology, which aims to enable a higher clock speed on top of the existing Turbo Boost clock.

Core i7-10700KF8 / 163.85.05.1N/A4.716125
Core i5-10600KF6 / 124.14.8N/AN/A4.512125
Core i9-10900F10 / 202.85.05.15.2 / 4.64.52065
Core i7-10700F8 / 162.94.74.5N/A4.61665
Core i5-10600F6 / 122.94.3N/AN/A4.01265

*Specifications in the table are unconfirmed.

According to the slide, the i9-10900KF and i9-10900F will have 10 cores and 20 threads each. The KF variant is listed with a 3.7 GHz base clock and 5.3 GHz TVB clock, and the F variant features a 2.8 GHz base and a 5.2 GHz TVB clock.

The i7-10700KF and i7-10700F are said to have eight cores and 16 threads each. The KF model seemingly ticks with a 3.8 GHz base and 5.1 GHz boost clock, respectively. The F model works with a 2.9 GHz base and 4.5 GHz boost, according to the slide. 

Lastly, the i5-10600KF and i5-10600F will reportedly sport six cores and 12 threads. The former has a 4.1 GHz base clock and 4.8 boost clock, whereas the latter is limited to a 2.9 GHz base clock and 4.3 GHz boost clock, Informática Cero's information claims. 

Intel hasn't confirmed the official launch date for its 10th Generation Comet Lake desktop CPUs. However, we expect the new chips to land in April if not sooner.

    125W TDP for the K series means 250W while under load. The 65W chips will be 130-150W while under load.

    Nice to see hyperthreading on the i5's.

    All these boosts are confusing, and 'more kinds of boost' seems like an odd way to segment the product stack.

    You forgot to mention that it need a new motherboard. Lga 1200 is the new socket.

    They really need to stop with the base clock TDP, as almost no one runs these cpus like that.

    Doing that would make it such that their CPUs look like the reincarnation of the FX-9590.

    In their defense, Inferno Lake is hot, greedy, and fast.
    Faildozer is hot, greedy, and still slow.

    yup. they mean A LOT of very technical stuff and it sums up to this:
    3.7 is the baseline cpu will hold if you provide 150W of cooling.
    5.1 will be held for 1 core for first 60 sec of heavy load on first core. 4.8 if you load more than one.
    in case of good VRM cpu can go to 5.2
    in case you still have low temp (I think it was under 60?) cpu will try to boost to 5.3 (probably ~300W of cooling required)

    long story short it means most people will not see anything more than 5.1 but marketing had to think of something to counter Ryzenvasion

    An agreement between the MB manufactures and Intel to keep the $ rolling in.

    Both turbo and PBO will boost (both power and clocks) as high as possible for a short period of time to get things done as fast as possible,especially if the CPU was idle for a while.
    If you keep a load going for a while intel's 14nm actually draws less power than TSMC's 7nm...140 for the 9900k against 170 for the 3700x.
