    For 60FPS target, I don't think you need a new CPU. Really. Consider one once you try to achive 144fps for 144hz panel.

    He's on 4K so even then trying to achieve 144fps etc. wouldn't really care about a new processor.

    Unless you are looking to get better system performance, rather then game performance, then i wouldn't bother upgrading since you game at 4K. That being said, if you do want better system performance/program performance depending on what you are doing, i wouldn't upgrade to a 6 core processor. I'd recommend 8 core definitely. If you want to save some money, get a 2700x instead of the 3700x, again your gaming performance will be the same between the two, for the most part, only your PC/programs performance will differ between the two.

    I guess I will buy 3950x for myself and slam it on this x370 board and pray to all the gods

    I plan on doing the same with my X470 board. I'm hoping all these teething issues (boost clocks, power usage, etc) are resolved by then. I was one of the early adopters of Summit Ridge and, although my experience wasn't as scarring as some others, I would like a smooth, trouble-free transition to Zen 2.

    more models coming and looks like there will be cheaper 3950 model
    AMD used the 3950 non x for the OCing WR's while the top binned 3950X is 100-000000051
    This looks interesting since we now know that 3900X is limited in OCing because of the 1 "bad" chiplet that cannot go above ~4.3~4.4 and this is exactly the max OC shown on the 100-000000033.
    and we also know that the 2nd better chiplet in 3900X can OC to 4.6~4.7Ghz, so if the binned 3950X can be OCed ~4.5~4.6Ghz all core that will be nice!

    All core clock of 4.5GHz is way outside power efficiency zone for 7nm Zen2 and 16C/32T may easily eat some 250W there. I would stay at 4.1~4.2GHz depending on actual behavior.

    The update being written tomorrow will basically be

    "Install the latest AB bios and this chipset driver"

    just wait and see. (happy to be wrong of course, but i've asked around and there isn't a new bios being prepared)

    I am waiting to see and hear from AMD themselves rather than downloading random stuff from the internet. Thanks anyway. ;)

    Yes of course, I am talking about max OC for benchmarks , we saw that 16C ES was only capable 4.3Ghz max clock on WC- similar to 3900X, so maybe the 3950X will be able to hit ~4.5Ghz max, but for 24/7 I think PBO will be enough[105W will limit 16C so PBO will be more effective then on lower core parts].

    I don't think this is very likely, you'd have to turn every part of the core on to do this and that never happens.

    Thanks for the in depth reviews on the Ryzen 3700/3900 proc's.
    i skipped the 2600 series,keeping my 1700 'till now :).....
    just ordered my Ryzen 3700x for £299 :), keeping my Hero v1 for the moment... just updated the bios and AMD drivers.
    thanks for your hard work Hilbert,all the best from Glasgow :)

    So....your saying the 9900k should be twice as fast as the 7700k.....i`d like to see the proof, given that most reviews ive looked at comparing the 7700k vs 8700k vs 9900k show very little performance gain as far as gaming is concerned.

    I had considered moving from my 7700k to the 9900k but so far have found no convincing reviews or evidence that says its a worthy upgrade for gaming...a few fps at most, i also considered the Amd 3700x/3800x and the 3900x paired with an Asus 570 prime board since getting my Corsair MP600 2tb but it looks like its a trade off....faster read/write speeds on my MP600 but lower fps in gaming not to mention the confusing mess with compatible memory, in all the years ive been using intel cpu`s ive never heard anyone mention memory latency so much as Amd users...its the main thing holding me back.

    You'll have a blast !

    I did exactly the same. Kept the X370 board, changed just R7 1700 to R7 3700x, and man, it's so much faster !
    Those extra 500-700Mhz + IPC improvements can really be felt !

    (Well some people have been lucky with their 1700 and it worked just fine at 4.0 -all cores-, mine unfortunately didn't, 3.7 was the highest it was stable, or 3.8 with uncomfortable voltages and power consumption)
    New 3700x boosts to 4.4-4.5 (with PBO+100, sX5) and sustains all-core clocks of 4.2 ... so quite a lot more work done every second !

    I'm guessing it's less of an upgrade for people with 1800X, but for ex-1700 owners it is definitely noticeable !

    (Oh, and I upgraded RAM too, from 3000-CL16 to 3733-CL16 (3600 with a bit of OC), to avoid any memory and IF bottlenecks and let it run as fast as it can)
