Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Power Consumption

At idle, Ryzen 7 2700X lands behind most of the Intel competition, but ahead of previous-gen Ryzen CPUs. First and second place in our chart go to a couple of AMD APUs, perhaps surprisingly.

Under a light CAD workload, Ryzen 7 2700X performs better and uses less power than its predecessor. This shows us that AMD didn't pay for better clocks with a sacrifice to power consumption. Its progress is already apparent at this point in the measurements.

Gaming tells a similar story; the performance increase is again more pronounced than the differences in power consumption.

When it comes to our stress test, AMD's Ryzen 7 2700X is much more reserved than its predecessor. We attribute this to the chip's XFR2 functionality, along with more granular frequency/voltage settings.

Even when we hit it as hard as possible, the new CPU stays stable above 4 GHz.

Performance rises and power consumption falls (if only slightly). There's truth to AMD's marketing material, so says our lab equipment. Ryzen 7 2700X really does deserve attention for these results.

    Once again, Tom's provides an incorrect comparison in this review. Intel's 8700K is comparable to the 2600 or 2600X and NOT the 2700 or 2700X. Just count the number of cores and threads and one should be able to figure that out O.o

    Whine all you want. Just because you down vote me only means you don't know how to read or count :P

    The 2700X costs $329, the 8700K costs $359. It is a very reasonable comparison to make.

    7820X is also there with the same number of cores and threads.

    It sure is nice to see an AMD chip up there in the thick of it with Intel's best offerings. Competition has finally officially returned. I'm impressed that AMD gained so much ground and managed to make the price more competitive than the 1800x was. It is slightly disappointing that overclocking remains less impressive than the Intel offerings, but everything else sort of makes up for that.

    I didn't feel like AMD was quite "there" yet with the 1000 Ryzens, but with the 2000 series I feel like we can finally say that they have arrived.

    Incorrect. It has nothing to do with price. Comparing like CPU architectures is the only logical course of action. 6 core/12 thread vs 8 core/16 thread makes no sense. Comparing the Intel 8700K 6 core/12 thread @ $347 to the AMD 2600X 6 core/12 thread @ $229.99 makes the most sense here. Once the proper math is done, AMD destroys Intel in performance vs. cost, especially when you game at any resolution higher than 1080P. The GPU becomes the bottleneck at that point, negating any IPC benefits of the Intel CPUs. I know this how? Simple. I also own a 8700K gaming PC ;-)

    Once again, whine all you want. Just because you down vote me only means you don't know how to read or count :P

    Now, do the tests again with meltdown/spectre applied on intel cpus, as you should.
    And you will see a VERY different story, with 2700k destroying 8700k in almost every measure).

    I will definitely check out that review as well. Thanks bfwhsm!

    Maybe you should read the comments on the AnandTech article. They all point out that the test results don't match any other site's results.

    ... because of the different testing procedure that he just referred to.
