AMD Ryzen 7 2700X Review: Redefining Ryzen

X470 And Ryzen Master 1.3

AMD's Socket AM4 was designed with robust power delivery capabilities that aren't entirely used by first-gen Ryzen processors. The 2000-series chips are much better at leveraging the platform's current headroom through their improved boost algorithms. Some value-oriented motherboards employ scaled-back power delivery capabilities, so AMD's second-gen Ryzen CPUs communicate with the platform to modulate performance based on what the motherboard can do. That's a necessary addition to accommodate Ryzen 7 2700X's 105W TDP, which didn't exist before this new chip line. As a result, less-capable motherboards may not expose the full performance potential of higher-TDP processors like the Ryzen 7 2700X.

The processor monitors Package Power Tracking (PPT) and Thermal Design Current (TDC) variables, measuring available margin to the motherboard's maximum power output and current, respectively. Electrical Design Current (EDC) also indicates the maximum current possible from the VRMs during peak/transient conditions. A control loop feeds the real-time telemetry data back to the Infinity Fabric, which then allows the processor to dynamically affect performance based on thermal and power conditions.

If the motherboard BIOS supports it, AMD exposes some of these monitoring features with its updated Ryzen Master 1.3 overclocking software. The fastest cores are identified during the binning process and flagged by Ryzen Master with gold stars on a per-CCX basis. The third- and fourth-fastest cores are marked with a circle.

AMD's software now supports per-CCX overclocking as well, and includes a built-in stress test. The warranty does not cover damage caused by overclocking, so exercise caution.

Because there are still plenty of 300-series motherboards available for sale, AMD designed a badge to let you know that a firmware update may be necessary before dropping a 2000-series CPU into one of those older platforms. Unless your 300-series motherboard has an out-of-band update mechanism like BIOS Flashback, you need a previous-gen Ryzen processor to update it. AMD also offers its Boot Kit solution, which is a loaner processor you can use to update the motherboard firmware.

Eventually, all 300-series motherboards will support 2000-series processors right out of the box. AMD expects X470 and X370 boards to coexist for the foreseeable future, so it may be possible to find excellent deals on those previous-gen motherboards.

*Note: requires a motherboard with at least six PCB layers. DDR4-2667 is supported on four-layer PCBs.

AMD's 2000-series processors support up to DDR4-2933 with a pair of single-rank DIMMs, though you need a six-layer motherboard to unlock that capability. Support drops back to DDR4-2667 for four-layer motherboards. Fortunately for enthusiasts, most mainstream platforms utilize six or eight layers.

From what we've seen thus far, X470 motherboards have an improved layout to facilitate aggressive memory overclocking. As you might expect, X470 boards in our labs are much more mature at launch than the 300-series platforms we battled last year. Thanks to this, we're easily running memory at DDR4-3466 with tight timings. Our motherboard team also noticed vastly improved overclocking with all memory slots populated, which was an issue on some X370 motherboards.

X470-based motherboards feature lower power consumption, higher multi-hub USB throughput, and improved power delivery. But they still have the same connectivity options as 300-series motherboards.

The first line in our chart covers Ryzen's I/O capabilities, which you then combine with one of the chipsets underneath to determine platform connectivity. A Ryzen CPU sports 20 PCIe 3.0 lanes. Sixteen are dedicated to the PCIe slots, while four lanes are dedicated to SATA ports or a 4x link for NVMe SSDs. Four of the SATA ports can also be assigned to SATA Express interfaces at a 2:1 ratio, yielding a maximum of two SATA Express connections.

As you can see, the X470 chipset offers the same connectivity options as its predecessor, with two USB 3.1 Gen2 ports, four USB 3.1 Gen1 ports, six USB 2.0 ports, and eight general-purpose PCIe 2.0 lanes that vendors can carve up for additional functionality (like hanging M.2 slots off of the chipset or enhanced 5/10GbE support).

    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.

    well i know what im upgrading to now. thanks

    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).

    (check out anandtech's review to get an idea)

    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.

    Multiple other sites have patched fully, but their results are drastically different than AT. Due to the obvious disparities, AT now says via twitter that it is investigating its results.

    Hi Paul, Igor, great review!
    A point to correct, on page 1: where it says "We still don't have a release date for the less expensive B470- and A470-based motherboards" it should be "We still don't have a release date for the less expensive B450- and A420-based motherboards". (Chipset numbers)
  • East17
    The the multi-core enhancement enabled on the Intel 8700K system or not ?!

    Because we see AMD's 2700X never goes beyond 105 W total power consumption while Intel's 8700K reaches 160W.

    Somehow, the Intel platform is allowed to use up to 65% more power and we believe this is not really a fair comparison.

    Thanks! Late nights around NDA time :) We'll fix it.

    We disabled MCE on all platforms (covered in test setup). I'll follow up with Igor to make sure this isn't a typo.

    Those are my thoughts exactly. Last year I was really happy to see AMD make tremendous progress on it's CPU architecture but if I were forced to choose between Intel and AMD, I still would have gone Intel. This was compounded when Coffee Lake came out. It was a no brainer then.

    Today's story paints a picture of how much the Zen architecture has matured in the last year. A year of development has smoothed over the wrinkles in the 1800x and made the 2700x a truly worthy competitor to Intel's 8700K.

    Maybe I missed it in the article, but does xfr2 or precision boost 2 work on x370 boards?

    It does work on 300-series boards, but performance gains could be limited by power delivery. we cover that right at the top of page 2.

    My current understanding is that the X370 motherboards do support XFR2 and Precision Boost 2.0. As long as your motherboard manufacturer has developed and released a compliant BIOS update, you should be good to go. I just installed my 2700X into an AsRock X370 Fatal1ty Professional Gaming motherboard (BIOS update P4.60) and this thing is running crazy fast. Running Prime95 @ 3.92Ghz on all 8 cores and 16 threads. Amazing! I do have a custom watercooling system, so that will definitely help the 2700X maintain full XFR2 and Precision Boost when I need it. Also, was able to increase my DDR4 speeds from 2933Mhz to 3200Mhz with no issues. I will try 3400Mhz and 3466Mhz later this weekend and see if those speeds run stable. So far, extremely happy with my upgrade ;-)

    Just to make sure I understood this correctly (and I apologize if I'm a little slow): any of the 2700X's "stock" benchmarks are ran at DDR4 2667?

    Aside from that, and this is just my .02, I feel like too much emphasis is placed on average framerates on the gaming benchmarks, and not enough on minimum framerates (though I do appreciate that you include both).
  • bfwhsm
    I reiterate: the other reviews may have received some form of patch (check out the test dates for the intel cpus; many date from January 2018)

    but it appears that only anandtech has applied the most recent and comprehensive April Meltdown/Spectre patch from MS.

    While there needs to be time for the dust to fully settle, for now, the message seems clear: after the security patches, AMD trumps Intel in every measure conceivable.
  • logainofhades
    Still no justifiable reason to change my 6700k, for something else, as my rig is mostly just gaming. Would be interested in F@H performance, of this CPU, though.

    We tested the stock 2700X at the supported DDR4-2933.

    We do use average framerates for comparative purposes during benchmark analysis, but minimum fare rates, while useful, can be deceiving at times. They only represent the single worst frame during any given recording, and sometimes you can get an errant result.

    To circumvent this, we use 99th percentile values, converted into an FPS measurement, for our final set of charts on the last page. This is a good metric that quantifies overall smoothness, so we use it for all cost analysis and the overall view of gaming performance relative to other processors.

    Price bracket is what the vast majority of reviews are based on. It has always been that way.
