Intel Core i9-7900X Review: Meet Skylake-X

Grand Theft Auto V, Hitman & Shadow of Mordor

Grand Theft Auto V

We measure performance during Grand Theft Auto V's F-16 flight sequence with the built-in benchmark.

Intel's stock Core i9-7900X beats the Core i7-7700K by a large margin, and a bit of tuning pushes it past the overclocked Broadwell-E model.

An overclocked Ryzen 7 1800X surpasses Core i7-6900K. The Ryzen 7 1800X won't face a significant pricing challenge from the new eight-core Skylake-X chip, but it will be interesting to see them head to head when we get our hands on one.

All of these processors provide a smooth gaming experience. However, the stock Core i9-7900X experiences some frame time variability in the early stages of this benchmark. The -7700K also encounters a familiar spike near the end of the flight sequence.

Hitman (2016)

The Core i9-7900X leads in both its stock and overclocked configurations. Oddly, as we go through our results, it's evident that this processor tends to provide solid performance in lightly threaded games, but struggles in some heavily-threaded titles. Of course, we would have expected the opposite to be true.

The overclocked -7900X suffers a frame time variance spike in the opening stages of this test that's rivaled only by the overclocked Ryzen 7 1800X.

Middle-earth: Shadow of Mordor

We expect the Core i7-7700K to lead in lightly threaded games, and for once, it does.

Core i9-7900X scales well with some tuning to take second place. The overclocked Ryzen processors also fare well in this benchmark, though their stock configurations contribute the only notable frame time outliers. All the CPUs provide solid performance, but it's notable that the lowest-cost processors only trail the leaders by a few FPS.

    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!

    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?

    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!!

    With these results and crippling by Intel, I think I can wait another 2 months for the ThreadRipper.
    Thank goodness for competition.

    Still would buy a Ryzen 1700, and overclock it, over this. The 7900x might be faster, but not enough to justify the higher price tag. I personally think the i9 was a knee jerk reaction to threadripper.

    Is there any way you could investigate the performance of AVX-512 on that CPU?

    The thermal paste has me worried that they won't be able to deliver significant gains over last year's models in that department.

    Why are you only using DX11 and 1080P. I would like to see 1440p and 4k game paly

    Lower resolutions put more of a load on the CPU.

    Like I said, I wasn't looking for positive reinforcement or validation as I am more than happy with my set up. But thank you for checking.

    Why an i5? I thought this was i7 only.

    well ... at least for 1000 bucks you now not only get a fairly powerful cpu but also a heater for the winter / grill in the summer ... and that just with the standard 10 core model.

    imagine the potential of the obviously unplanned and hastily shoehorned in 12-18core models once they come out in 2018 ... your rig will go nova ^^

    I agree. Imagine if you ran Grand Theft Auto 5 in 640x480 mode. Your graphics card would barely have any work to do. All that's left is whatever the game asks from the CPU. That's when you see which CPU shines brightest.

    Regarding the 7900x, I'm glad to see that Intel responded so quickly to Ryzen. It's too late in the development cycle to make Skylake-X a Ryzen killer, so what we get to see is what Intel had planned for us before AMD made it's comeback.

    The article isn't very flattering toward Skylake-X but it's a much better deal than Broadwell was a year ago. Mostly higher performance at a lower price point. Good for Intel! Good for competition. Still, if I were building a PC right now I might go Ryzen.

    You're wrong. I don't even think you understand how processors are made. No company just says "they released that?! Quick make a 10 core processor".

    If 30% increase in performance isn't enough to justify the price tag -- than the processor was never for you to begin with. Neither is Threadripper. These processors are not for budget builds or for feeling the need to justify your decisions to save money. They are for a specific market that is very little of Intel's bottom line.
