AMD's Ryzen processors trail most of the Intel competition during this test, while the overclocked HEDT Core processors deliver 100 FPS+ on average.

The overclocked Ryzen 7 1800X and Ryzen 5 1600X offer nearly the same performance as a stock Core i7-6950K. That chip sets itself apart once we crank up its clock rate, though. Only an overclocked Core i9-7900X is faster.

Rise of the Tomb Raider

Rise of the Tomb Raider recently received a patch that significantly improves Ryzen's DX12 performance, making this one more title optimized for AMD's latest platform.

Nevertheless, Core i9-7900X performs well in our DX11-based test, taking first and second place in its overclocked and stock configurations. Broadwell-E is bested just slightly.

Ryzen 7 1800X trails the Core i7-7700K in its stock form, though a bit of tuning propels it into a lead. The Core i9-7900X beats its predecessor, but trails the less expensive AMD chip and Intel's own Core i7-7700K.

The Ryzen 5 1600X and Core i7-6900K contribute a majority of frame time outliers. However, all of these CPUs provide a smooth gaming experience.

  • Pros: 10/20 cost now $999
    Cons: Everything else

    My biggest problem with this Intel lineup is that if you want 44 PCIe you have to pay $999. No, thanks. My money goes to AMD ThreadRipper.

    Good review!

    Doubt many who purchase such high end cpu for gaming runs at a low full hd 1080p resolution, i know its more cpu taxing to run lower res at higher fps but that's for the sake of benchmarking the cpu itself.

    I would like to see 1440p + 2160p resolutions on a suitable high end card (1080ti or equalent) benchmarked with the cpu as well as it would represent real scenarios for the peeps considering such cpu.

    Thanks for a good review!

    So it seems like de-lidding the x299 processors is gonna be a standard thing now to replace the TIM?

    Meet netburst 2.0 that not only can hit 100c at only (4.7Ghz)1.2v on good water cooler but only barely beats a 7700k not overclocked in games. All this is yours for the low low price of 3X. Its slower than the old 6950x in a few tests with was odd.

    There's obviously a problem if the delta is that high.

    The differences would be less noticeable at higher res than 1080p, so.... you'd just see less dissimilar numbers.

    Hmmmmm. I bought a Ryzen 1700, a water cooler, Asrock B350 MB, 16gb ram 3200Mhz for $590 plus tax. I live in New Jersey. I was very nervous about making the purchase as I knew this was coming out this week but the sale prices got me. Unless you all think I got ripped off, (DON'T TELL ME). But in all honesty I have not regretted the purchase one bit!! I even managed to save enough to get a GTX 1080 FE GPU. I did have a few bumps in the road getting the system stable (about 3 hours configuring after assembly) but I am VERY happy. I used Intel primarily and never really considered AMD other than for Video adapters and SSDs.
    After reading this along with other articles and YT videos, I have no regerts as I enjoy my Milky Way and play my games among other things.
    Just my experience. I am not seeking positive reinforcement nor advice.
    I just feel very satisfied that I did not wait and cough up 3oo more fore something I could have for less. I know, I know it makes no sense.
    But come on fellas, its the computer game!!

    Depends on which watercooler and which ram, but not really.

    Wow, compared to the Ryzen 1800X, the Intel Core i9-7900X:

    is about 25-30% faster
    costs 105% more
    uses 35-40% more power

    Ryzen looks really good here, and together with the temperature problems, Intel seems to be in some deep shit.

    Too little, too late. Does Intel really think that just because it has "Intel" written on it that it must be worth $200-$300 than AMD?
