    Great review as always but on the power consumption fron given that the 1950x has six more cores and the 1920 has two more they are more power efficient than the 7900x is every regard relative to the high stock clocks of the TR

    "Ryzen Threadripper 1920X comes arms with 12 physical cores and SMT"

    ...

    Judging from Threadripper 1950X versus the Threadripper 1900X we can infer that a difference of 400 megahertz is worth the tdp of 16 whole threads.

    I never realized HT / SMT was that efficient or is AMD holding something back with the Threadripper 1900x?

    Your sister site Anandtech did a retest of Threadripper a while back and found that their original form of game mode was more effective than the one supplied by AMD. What they had done is disable SMT and have a 16c/16t CPU instead of the 8c/16t that AMD's game mode does. http://www.anandtech.com/show/11726/retesting-amd-ryzen-threadrippers-game-mode-halving-cores-for-more-performance/16

    Hats-off to AMD and Intel. The quantity (and quality) of processing power is simply amazing these days. Long gone are the times of taking days off (literally) for "rasterizing and rendering" of work flows

    ...or is AMD holding something back with the Threadripper 1900x?
    I think the better question is, "Where is AMD going from here?"

    The first revision Socket SP3r2/TR4 mobos are simply amazing, and AMD has traditionally maintained (and improved!) their high-end stuff. I can't wait to see how they use those 4094 landings and massive bandwidth over the next few years. The next iteration of the 'Ripper already has me salivating :ouch:

    I'll take 4X Summit Ridge 'glued' together, please !!

    This was a great article. While there's no way in hell I'll ever be able to afford something this high-end, it's cool to see AMD trading punches once again.

    I'm confused.
    "We maintained a 4.1 GHz overclock"
    Per chart "Threadripper 1920X - Boost Frequency (GHz) 4.0 (4.2 XFR)"

    So you couldn't get the XFR to 4.2?
    If I understand correctly manually overclocking disables XFR.
    So your chip was just a lotto loser at 4.1 or am I missing something?

    EDIT: Oh, you mean 4.1 All core OC I bet.

    actually the view should be you cannot afford not to go this way. You save a lot of time with gear like this my two 1950X rigs are killing my workload like no tomorrow... pretty impressive...for just gaming, maybe......but then again....its a solid investment that will run a long time...

    A big die shrink like that would be helpful but I think that Ryzen suffers from other architectural limitations.

    Ryzen has a clock speed ceiling of roughly 4.2Ghz. It's difficult to get it past there regardless of your cooling method.
    Also, Ryzen experiences nasty latency when data is being shared over the Infinity Fabric. Highly threaded work loads are being artificially limited when passing between dies.
    Lastly, the Ryzen's IPC lags behind Intel's a little bit. Coupled with the relatively low clock speed ceiling, Ryzen isn't the most ideal CPU for gaming (it holds up well in higher resolutions to be fair).

    Threadripper and Ryzen only look as good as they do because Intel hasn't focused on improving their desktop chips in the last few years. Imagine if Ivy Bridge wasn't a minor upgrade. If Haswell, Broadwell, Skylake, and Kabylake weren't tiny 5% improvements. What if Skylake X wasn't a concentrated fiery inferno? Zen wouldn't be a big deal if all of Intel's latest chips were as impressive as the Core 2 Duo was back in 2006.

    AMD has done an amazing job transitioning from crappy Bulldozer to Zen. They're in a position to really put the hurt on Intel but they can't lose the momentum they've built. If AMD were to address all of these problems in their next architecture update, they would really have a monster on their hands.

    Sure Billy Gates, at 1080p with an 800$ CPU and an 800$ GPU made by a competitor... sure...

    At 1440p and 2160p the gaming performances is the same, however your multi-threading performances are still better than the overprices Intel chips.
