    comparing the wide range of 8700k cb scores.jpg
    By this collection of CB results from a wide range of reviewers, taking off the top 4 scores for being non-stock, the remaining scores say that for the large part - 45% -, you won't get advertised Max Turbo, so I guess it's a good thing Intel doesn't guarantee it.

    So, yeah, Intel won't sell a lot of them when people discover they aren't performing.

    At least this "production" run has these problems. Maybe the next production runs in a few months will be better?

    the idea is not about the graph and not about reviewers testing a "wide variety" of 8700k. all 8700k are designed the same way, difference would be silicon so if clocked the same, they yield no difference.

    the term in IPC, once again, should technically be including the entire CPU which includes extra cache and faster IMC. if a software using the extra cache/IMC then you will see it being much faster than 7700k at same frequency per core, just how it is.

    a person riding a consumer motorcycle at max speed would not mean if the consumer bike is replaced with a race bike. hardware is different, software needs to take advantage of that difference. in this case the software didn't take advantage of that difference thus no IPC gain. if it did, we will see IPC increase.

    a nice example would be samsung SSD and its TLC cache to boost computing experience. hence me and @tilleroftheearth dont really like sammy ssd that much when it comes to steady state or consistent workloads. MLC ssd ive no problem with tho.

    I think you may have gotten the point of the graphs after all :)

    The 8700k silicon isn't performing, with about 45% of the CB scores being under the average of 1425cb - with a range of 1262cb - 1364cb.

    We still don't know for sure if the 1425cb is totally stock, as this may all be down to motherboard makers interpretation of Intel's specs for "stock" defaults.

    i dont need to look at it to understand the graph i mean most reviewers do graph the same way, but it looks like you dont understand what IPC really is tho. but i'll leave it at that.

    Yeah, I don't like the results either, no IPC improvement demonstrates that this isn't really Coffee Lake architecture it's 6 core Kaby Lake, but we were already told that by Intel, the real Coffee Lake is out past 2H18 at this point, a date range which can change again.

    Architecture changes compared to Kaby Lake
    Coffee Lake features largely the same CPU core and performance per MHz as Skylake/Kaby Lake.[7][8]

    I did a bench with 7700K@4.3GHz as stock 8700K. For joo bruh:D Aka tested with all time high BGA clocks.

    This is from my older 6700K@4.3GHz

    As joo can see... There ain't big difference. Then do your math with 50% more cores and with same IPC. I wonder what the numbers will be?:rolleyes: Dan'g I can't do math. Too old:eek: You're welcome!!

    Edit. Very strange. Almost on par with @Talon's 8700K@4.3GHz. How is this possible?:rolleyes: I will try... 957+50% more cores = 1435.5cb. Is this correct math?

    CFL is a refresh, so of course its same architecture. we should only focus on the changes and differences to see where the real benefits are. doing a review to show IPC increase imo is kinda silly but i guess many do wanna see it, me included :)

    Strange. Almost same score for 4.3GHz. How is this possible?:rolleyes:

    Same score with a few things up.

    all that matter is if that 870TM1 cpu heatsink comes with 2 fans and if I can get my hand on a 6ghz 5.2ghz which i probably could from caske for wallet rape at $1000 CAD... totally worth if for 2 fans cpu heatsink.

    if its 2 fans then run cpu at 5ghz at say 1.3v will still yield to a decent temp without having to do max fan all day.

    You can. The 4.4 beta is able to do so without any issues. The percentage is only the usage, which is kinda useless to know if you don't know the clock speeds. Like on Mr.fox video you can see how his CPU throttles down to 4.2ghz, if the same is happening to you because you undervolted to much, then the temps are less impressive, but still good.
