    A good point, I know people who make money snapping up new products and selling them marked up while vendors try to get more to the shelves and even having one extra is nice.

    Although you could flip one of the two, you'd want a larger quantity to really make either idea effective. Like a tray or two of CPU's from a couple of sources so you have a good cross section of samples :)

    Still, I wouldn’t let the chance go out the door getting two or three chips, then pick the best one(of course If you have the money).

    You always give your friend the fastest one, or sell the slowest one and keep the fastest one, but that's not so much binning as being aware and actively testing your components for performance. :)

    @Talon

    Would you please, when have some time to spend, run CB15 at same defined clock(on all cores) of your choice but changing the cores used from Task Manager or by the software itself on 4/8thread.

    This to evalute IPC gain over Skylake/Kabylake from an independent test as in this review? sorry 5 secs after the bookmark on vid, at 15:04


    Thank you

    Rewatch the video, it wasn't about IPC improvement - there isn't any:
    no ipc gain between 7700k and 8700k.jpg
    Look at the wide range of results from the 8700k's reviewed, a wide range of performance, due to multi-core enhancement - overclock - enabled pushing the performance up higher than stock - the lowest actual scores in this graph are the "real" stock 8700k CB scores and also show turbo maximum isn't always achieved:
    wide variance in 8700k Cinebench results.jpg
    Watch the whole video again, there's a lot of good info in there.

    If not for the multi-core enhancement OC + All Core Sync running all 4 cores at 4.7ghz instead of stock boost, bumping up the stock scores, the "real stock" 8700k is benchmarking CB under the stock Ryzen 7 1700x, and just over the Ryzen 5 1600x.

    Much different results at stock, it seems too convenient to be accidental. These MB makers put the defaults in the BIOS to run the 8th generation CPU's with multi-core enhancement OC'd and All Core Sync, that's not cool.

    jayz2cents blew catching the MCE "stock OC" + All Core Sync, and published bloated scores:

    "JayzTwoCents 19 hours ago
    FOR THE RECORD.... after we were called out for testing with default board settings (by the audience by the way, not you) ASUS reached out to me to explain that MCE is OFF by default and Sync all Cores should NOT have been enabled by default, I explained to them that this is indeed FALSE.

    ASUS themselves aren't even clear on what the default settings were
    and it was only after clearing CMOS again and showing them what the optimized defaults are did they agree that they need to reel in their BIOS team and get to the bottom of this...

    I also said in my video that we as reviewers need to be better at this, so although you calling me out in this video is accurate, I had already updated my content showing where the discrepancy was.

    ...channel infighting redacted...

    As for the "Intel hiding something" of course they are... they are widening their stack on purpose... It sucks, but its business and it doesn't take much investigative research to figure that out."

    But, it's clear a number of reviewers didn't catch this and published bloated scores at "stock". This is really annoying for reviewers, getting caught in the middle of this effort to pump up stock scores. You trust the vendor to play straight, and then this happens.

    IDK how this is going to shake out, but it's clear score pumping occurred, due to Intel's inability to dramatically outperform Ryzen at "real" stock settings.

    Yup, and it's not just the 8700k, it's also going to affect the scores from the other CPU sku's reviewed on those same z370 motherboards.
