Test Bed and Setup

As per our processor testing policy, we take a premium category motherboard suitable for the socket, and equip the system with a suitable amount of memory running at the manufacturer's maximum supported frequency. This is also typically run at JEDEC subtimings where possible.

It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.

** After Initial testing with the ASRock Z370 motherboard, we noted it had a voltage issue with the Core 9th Gen processors. As a result, we moved to the MSI MPG Z390 Gaming Edge AC for our power measurements. Benchmarking seems unaffected.

We must thank the following companies for kindly providing hardware for our multiple test beds. Some of this hardware is not in this test bed specifically, but is used in other testing.

    For once, we're going to do the first comment!

    (What does everyone think of the article, and Intel's new CPU?)

    Okay. That's well-played... Reply

    My take on your data: worth it if you have something a lot faster than a GTX 1080 since it looks GPU-bound for most of the gaming benchmarks at med-high resolutions. 2080Ti users and SLI users will probably get the most out of it from a gaming perspective.

    Skylake-X with that AVX512 perf, though...

    One issue we always have every generation is sourcing GPUs. Going up to a vendor and asking for 3-4 cards is typically a no go. This is why I've done a range of resolutions/settings for each game, so cover everyone who wants to see CPU limited scenarios, and others that might be more real-world oriented. Reply

    Ian, how can you claim 9900k is the best when you never tested the HEDT parts in gaming? Making such claims really makes anandtech look bad because it sounds like a sales pitch and you omitted that entire HEDT platform from the results. I hope you fix this oversight so skyX can be compared properly to 9900K and the upcoming skyX refresh parts! And of course, AMD HEDT parts.

    There was supposed to be a part2 to the i9-7980XE review and it never happened, so gaming benchmarks were never done, and i9-7940X and i9-7920X weren't tested either. HEDT is a gaming platform since it has no ECC support and isn't marketed as a workstation platform.

    IF intel says the 8-core part is now "the best" you ought to be testing their flagship HEDT parts which also were claimed to be the best.

    p.s. It would be nice if you can also do Zbrush benchmarking for all the cpu reviews. it runs entirely on the CPU with no GPU accelerations and it comes with a benchmark test/score built into the app. Zbrush is a very common 3d app these days. Also its useful to mention in a review how many polygons or subdivision levels can be displayed in zbrush by the cpu before you see a slowdown. thanks. Reply

    "Ian, how can you claim 9900k is the best when you never tested the HEDT parts in gaming?"

    Beg your pardon? We have the 7900X, 7820X, and a couple of Threadrippers for good measure. Past that, the farther up the ladder you go in Intel HEDT, the lower the turbo clockspeeds go, which diminishes gaming performance.

    sorry, I was mainly just looking for the flagship products and they have no gaming benches at all, 2990WX, 2950X, and 7980XE, these top end "best" parts have no gaming benchmarks. I wanted to see how they compare to the 9900k or to the refreshed skylakeX which will come out. if for example someone wants to buy a chip that is good for both raytrace rendering and games (game developers, etc.) they will want to see all these benches.

    Why would you buy a 2990WX, 2950X, and 7980XE

    to play games on?
