    Oh look, a huge Coffee Lake leak on the eve of AMD's big launch of Ryzen Threadripper, what a surprise. Intel is kicking up its Core i7-8700K to a 6C/12T design, shifting away from the Core i7-7700K and its 4C/8T power.

    There are some benchmarks of the purported Core i7-8700K, with a CPU-Z benchmark result of 2323 for single-thread performance, and a multi-threaded score of 13,980. This is a big increase from the 4443 on the 7700K, but is achieved from the higher CPU core count (4C/8T vs 6C/12T).
    Edit: For comparison I just tested my own 5820K @ 4.5Ghz using same CPU-Z version 1.78.3 (couldn't find 1.78.1) : Single = 2043, Multi (HT disabled) = 11163

    Intel will be clocking the Core i7-8700K at up to 4.7GHz on maximum single-core CPU clocks, while it'll hit 4.6GHz on dual-core, 4.4GHz on quad-core, and 4.3GHz on hexa-core. It'll support dual-channel DDR4, feature a 95W TDP, and integrated graphics. The new 8700K will be joined by the 8700, with slightly lowered CPU clocks of 4.6/4.5/4.3/4.3GHz for single/dual/quad/hexa-core CPU clocks, respectively. The Core i7-8700 will feature a lowered 3.2GHz base frequency compared to the 8700K and its 3.7GHz base frequency, as well as a lowered TDP of just 65W. As with every non-K processor from Intel, the Core i7-8700 won't be overclockable. Intel's new Coffee Lake CPUs will be launching in Q3 2017, with the flagship Core i7-8700K to come in at around $349.

    Intel still thinking 24 PCI-Express lanes are considered acceptable....

    Yeah...NO.

    Its from the chipset, 16-24 more will be from the CPU, well at least 16 more
    40 total is fine for mainstream.

    I'm very disappointed with Intel and the fact that Coffee Lake isn't compatible with z270, but hopefully they'll get their **** together in time for my next upgrade, because I'm done with low effort AMD.

    Its just a rumor that it wont be backwards compatible.
    Looks like the CPU will come earlier than the motherboards with new chipset, the CPU release was pushed forward

    Just thought I'd point it out....

    The multi thread score of a 7700K is just under 10000 according to CPU-Z 1.78.3 (and my Ryzen 1600X scores 2272 ST and 13040 MT in that same test. No overclock, for reference).

    The 8700K looks like a good chip though, as is the 7700K, annoying that they could have had it out earlier really and it took a kick from AMD to get it out now!

    According to latest CPU-Z 1.80.1

    Mine, 5820K, 6/6 (HTOFF), 4.5Ghz = S:480 M: 2795
    1700 = S:359 M:3905
    1800x = S:400 M:4542
    7700K = S:492 M:2648

    7700K with its 4C/8T is as fast as Overclocked 5820K with 6C/6T (I know if I enable HT my MP score will go up, but i never use that feature, its IMO useless when you go 6-8 cores)
    Im sure coffee lake will not be slower than than what we have today in single core, leaked benchmarks if they real show improve, single core score higher than 7700k.
    So lets take 7700k without overclock, 2648/8 = 331 x 12 = 3972 thats rough estimation, before any overclock and native higher clock of 8700k.
    Thats already higher than 8 core 1700 Ryzen.
    With Overclock and it will go higher than 5Ghz, there is no doubd about that, a CPU with 4.7Ghz Turbo, will do at least 5.2Ghz overclock without delid, but lest be conservative and say 5Ghz (so fanboys wont complain)
    We have a 6 Core CPU with same multi core performance as Ryzen 1800x and best in class single core performance.

    Im upgrading.

    I did some math, selling my X99 Sabertooth, 5820K and 32GB 2666Mhz RAM, my motherboard has broken USB 3.1 port and I have one year warranty so it means ill get a new mobo, i have some strange memory issues, maybe because i pushed Uncore to 4500Ghz locked for last 2 years, but now every Windows be it installed or installing will crash on load, so i had to increase memory voltage, change memory training setting and everything works fine but if the CPU is responsible for this then I will get a boxed CPU.
    I dont need to replace my RAM, i kept the nylons on the logos, and hidden the boxes so i just need to clean it and pack it and its brand new.

    So after buying:
    8700K
    Mobo - 200-300$. maximum 350$ (any mobo that has at least 8 SATA, TPM port and two NVMe ports will do fine)
    32Gb, two stick of 16Gb 3200Mhz (mine is quad channel kit so cant use it)
    and selling my old parts, the whole upgrade will cost me maybe 200-300$ if not less and if im greedy enough and wait for buyers i might sell for more money and upgrade for free.

    Well I can't argue that it wouldn't be an upgrade for you, especially on the gaming side so good luck with the sale of your parts (easy I would have thought).
    I sold my i5 4690K, motherboard and RAM to get my Ryzen and only had to shell out an extra £70, I'm very happy. But then again I've always felt more comfortable being with AMD :)

    I'm selling my i5 2500k to a mate for 250 quid. That's the whole system including 16 gig of DDR 3 ram, a 128Gb SSD, an 8 year old ASUS monitor and an Asus 7970 3Gb. I am left with 256 Gb SSD and 2 Tb HDD, 850 Watt PSU and a recent RX 570 (I got mine before the miners raised the price). Hoping to just get a new mobo, 16 Gb of DDR4 and a 8700k. Bang that in my case and I am hoping it will be an effective upgrade over the 2500k.

    Is there enough performance difference between the 8700k and 6700k in gaming to do a full mobo/cpu/ram overhaul?

    Coffee Lake 8000-series processors and 300-series chipsets use a new socket LGA1151v2, which remaps a few pins to VCC (+5V power) and VSS (ground), so they are not compatible with current LGA1151 motherboards or processors.
