Ryzen 7 2700X – Performance and Verdict Review
AMD Ryzen 7 2700X – Test setup
As an eight-core chip, the Ryzen 7 2700X could be considered a competitor to the Intel Core i7-7820X. However, that chip only runs on Intel’s high-end LGA2066 platform. Instead, it’s only really right to compare the top-of-the-line processor from AMD’s mainstream platform (AM4) to Intel’s top-of-the-line for its mainstream platform, LGA1151. This puts it up against the Intel Core i7-8700K.
It makes for a slightly lop-sided comparison, as Intel’s chip has fewer cores yet runs at a faster clock speed. Ultimately, though, it’s the main choice buyers will be looking to make.
Also, the new Ryzen 5 2600X is a direct, six-core competitor to the 8700K.
Its slower clock speeds means it’s almost guaranteed to be a little slower across the board, but with the right pricing it could make for a great choice for gamers.
We tested the AMD processor on a new X470 motherboard (the Asus Strix X470-F Gaming) while the 8700K was tested on a Z370 motherboard (the Asus TUF Z370-Pro Gaming). Both systems were equipped with the same Zotac Nvidia GeForce GTX 1080 Ti graphics card, Corsair Vengeance RGB 3000MHz RAM (CMR16GX4M2C3000C15), Samsung 860 Evo SSD, Corsair RM750i power supply and NZXT X52 cooler.
We’ve also included some comparisons to older AMD processors that were previously tested on an X370 motherboard and Intel processors tested on a Z270 motherboard.
AMD Ryzen 7 2700X – Results
Cinebench R15
Kicking things off with the ever-reliable Cinebench R15 benchmark, we can see that the higher clock speed of the 2700X delivers a nice 11% improvement in the single-core test over the 1800X, while the multi-core test also shows a 10% improvement.
The advantage of those eight cores compared to the six of the 8700K is also plain to see with a massive 28% lead in the multi-threaded test.
However, the clock speed advantage of the 8700K is also clear, with Intel’s chip holding a 14% lead in single-thread performance. Meanwhile, AMD’s six-core competitor – the 2600X – is another couple of percentage points behind, although Intel’s advantage in the multi-thread test is less than 1%.
POV-Ray
Moving on to the POV-Ray benchmark, the picture is all but identical. In the multi-core test, the 2700X holds a 24% advantage over the 8700K; but in the single-thread test, the 8700K pulls out a 16% lead. Meanwhile, the 2600X is within 5% of the 8700K in the multi-thread test but falls back by 18% in the single-thread test.
The clock speed deficit is unlikely to be noticeable in day-to-day use, since most apps don’t put that much strain on your CPU. Particularly demanding apps will have some sort of multi-threaded capability, which means the 2700X has an advantage.
However, there are a few instances where the clock speed advantage of the 8700K will shine through. For instance, video rendering using Adobe Photoshop is quite poorly optimised for multi-core processors, taking little advantage of more than four cores. As such, clock speed is king here.
Gaming
Then, of course, there’s gaming. Most modern games have a degree of multi-thread capability, but only for ancillary tasks such as physics or audio calculations. The main core of the game that tends to determine the FPS you’ll get is always single-threaded, so clock speed is again king.
We can see this in our tests, although only at lower resolutions where the graphics card isn’t the major performance bottleneck.
In Deus Ex: Mankind Divided, the 8700K holds just a 0.1fps advantage over the 2700X at 1440p with very high detail settings. However, at 1080p with high detail settings this lead stretches to 15fps, although both cards still deliver over 115fps.
It’s a similar picture in Rise of the Tomb Raider, where the 8700K has just a 1.3fps lead at 1440p with Ultra detail settings. Drop down to 1080p at high detail and this increases to 12fps.
Following the release of the Intel Core i9-9900K we retested the Ryzen 2700X to see how it compared against modern competition. While the Ryzen 7 2700X lagged behind the i9-9900K for HD gaming, the gap was reduced to just one frame-per-second for 4K content. This is despite Intel’s 9th-Gen i9 CPU costing double the price. This goes to show that if you’re intent on playing games in Ultra HD, the Ryzen 7 2700X is easily one of the best value processors available.

AMD Ryzen 7 2700X – Power consumption
One of the biggest factors to leave us impressed about the 1800X was that AMD had for a long time struggled to get power consumption down to a level that competed with Intel’s chips – but with that processor AMD achieved power consumption parity.
Now, we’re not testing directly comparable chips this time as the 2700X is eight-core and the 8700K is six-core, but it’s still interesting to note how much more power the AMD chip uses. Moreover, the 2600X uses quite a bit more power than the Intel chip, despite them both being six-core.
AMD Ryzen 7 2700X – Overclocking
The first generation of Ryzen processors weren’t great for overclocking. They could be pushed hnigher, but often required quite a high voltage and consumed considerably more power.
However, AMD is bullish about how overclockable its new processors are, and there have been widespread rumours of processors hitting well over 5GHz in extreme conditions.
In our trials, we didn’t find progress to be all that straightforward. It certainly doesn’t help that the default starting voltage – whether you use the BIOS or AMD Ryzen software – is 1.2V, when you actually need at least 1.45 to start pushing the CPU beyond its default speeds.
Also, as before, any overclocking immediately disables all the automatic clock speed tweaks of Precision Boost and XFR, so unless you can overclock all eight cores to beyond 4.
3GHz, your single core performance will likely go down.
Sure enough, in our tests, we struggled to get the 2700X much higher than 4.3GHz without pushing the CPU voltage up particularly high. In this regard the Ryzen 5 2600X is the more appealing option as it also reached 4.3GHz, which is actually beyond its default single-core clock speed.
In contrast, the 8700K we used for testing immediately overclocked to 5GHz without changing any settings other than the CPU multiplier, though notably this also resulted in a big jump in power consumption. It leapt from 141W to 218W when the CPU is fully loaded.
We also tested the Wraith cooler and it performed impressively. It kept the CPU at just 71C when under full load, while only producing 41dB (from 30cm away, not in a case). Our monstrous NZXT Kraken X62 all-in-one liquid cooler only had the CPU 6C cooler, though notably it was all but silent.
We also compared Cinebench results for both coolers to see if the new XFR2 overclocking held back performance for the Wraith cooler at all, but in fact it produced exactly the same average score.
Why buy the AMD Ryzen 7 2700X?
In some ways, the 2700X and 2600X are everything we’d hope for from a second-generation Ryzen processor. They’re a little faster than the first generation, they fit into existing AM4 motherboards, and they’re priced just as competitively.
If you bought, say, a Ryzen 5 1500X last year and are looking for an upgrade then these fit the bill perfectly. On the other hand, if you bought an 1800X, or even a 1700X, then the case is less clear-cut. Those older chips can be overclocked to somewhat comparable levels, so you’ll likely only see a modest performance gain.
Meanwhile, when it comes to choosing one of these processors or one of Intel’s latest, the reality is that for most users – and particularly gamers – six faster cores are more often more useful than eight slower ones, so the 8700K will be the better choice.
Unless, that is, you opt for the 2600X. It has comparable performance across the board but has a far more competitive price, making it the clear choice for those on a slightly tighter budget.
