AMD Ryzen 7 2700X review: the Intel Coffee Lake killer

Subscribe to PCGamesN on YouTube

The AMD Ryzen 7 2700X is our first taste of AMD’s second-gen Ryzen processors... and it’s a hell of an introduction. For now it’s the top Pinnacle Ridge chip, with AMD withholding the Ryzen 7 2800X to see how Intel will respond. And they’re going to have to do something as the 2700X is making it difficult to now recommend an Intel Core processor over the new AMD Ryzen 2 CPUs.

Check out our pick of the best CPUs for gaming right now.

It’s just over a year since AMD launched the first-gen Ryzen processors and shook the CPU world up. Their disruptive mix of high core-count and aggressive pricing made Intel sit up and take notice, but they weren’t able to knock Intel off the top spot straight away. They were, however, a marker and we’ve been waiting to see what AMD had learned from the first outing of the Zen architecture.

So, what have they done to improve on the original Ryzen design, and how do they now compare with the Intel competition?

The Ryzen 7 2700X - with the Ryzen 5 2600X  as very capable backup - is the inevitable maturation of the Ryzen range, and is definitely more of an evolution than a revolutionary new processor. This isn’t the AMD Zen 2 architecture, this is their tweaked Zen+ design. It’s essentially been created using the same Zen architecture as the first-gen chips, but is now based on the new, smaller GlobalFoundries 12nm production process.

But the fact that these Pinnacle Ridge processors represent an evolutionary design over the original Summit Ridge CPUs is definitely no bad thing - the initial Ryzen processors were impressive first-gen CPUs. These Ryzen 2 chips, however, have definitely benefited from a year’s worth of engineering and tweaking.

To start with, however, it’s worth mentioning that there has been no change in the core-count of the new second-gen Ryzen range, we’re still talking about the Ryzen 7 2700X sporting the same eight-core, 16-thread configuration as the Ryzen 7 1800X and 1700X of the previous generation. Despite being a smaller production process, the 12nm lithography was never going to allow AMD to squeeze any more cores in - not to mention the relatively limited time they’ve had to work on them.

We were told by AMD’s James Prior at CES that the 12nm process was “not an area statement, it’s a power efficiency statement. The area is not going to change much, but the ability for us to manipulate the frequency voltage curve has improved.” And that has meant they’ve been able to up the clock speed of the new Pinnacle Ridge processors.

The Ryzen 7 2700X has the same 3.7GHz base clock as the previous top Ryzen processor, the 1800X, but now offers a 4.3GHz maximum boost frequency. Obviously, that’s the maximum clock speed you’ll get when only one core is active, in line with the way Intel measure their chips, but the difference now is that even when all eight cores are being stressed the Ryzen 7 2700X will be able to get closer to that speed than the 1800X ever could.

That’s because AMD have improved the Precision Boost and XFR features of the SenseMI technology. Previously the Summit Ridge chips would refuse to budge from the base clock if any more than one core had something going on, with Pinnacle Ridge - in fact, with all the Ryzen 2000 series chips, including the Ryzen 5 2400G and Ryzen 3 2200G  - Precision Boost 2 is far more opportunistic.

AMD Precision Boost 2

That means the Ryzen 7 2700X will always aim for its highest frequency, even when all the cores are stressed, by checking against CPU temperature, load, and current. And it will do it with increased granularity too, if it’s getting too toasty at 4.15GHz then it’ll drop down to 4.1GHz or 4.06GHz instead of just resetting back to the 3.7GHz base.

But you don’t need to worry about compatibility because AMD have already promised that the AM4 motherboard platform will form the base of our Zen PCs up until 2020 at least. So the Ryzen 7 2700X is completely compatible with the existing 300-series boards, despite launching with a new X470 chipset.

Memory compatibility, a big problem for the first Ryzen launch, is now a non issue too. We haven’t experienced any RAM issues with the new chips, or any AMD CPUs, for a long while now.

AMD Wraith Prism - so pretty!

The Ryzen 7 2700X is also a better overall package now. All the second-gen Ryzen processors now come with a CPU cooler as standard, and with the Ryzen 7 2700X you get a doozy. The new Wraith Prism is a proper RGB LED air-cooler, with a hefty heatsink and direct contact heatpipes.

This isn’t the sort of useless paperweight you get with Intel processors, this is a genuinely useable cooler.

AMD Ryzen 7 2700X performance

Let’s start with the good news. In productivity tasks the Ryzen 7 2700X absolutely flies. Throw some rendering at it with the Cinebench test and it powers through it faster than any CPU close to its price point. Chuck some video encoding its way and the competing Intel six-core genuinely looks like the poor cousin.

If you want some numbers, the Ryzen 7 2700X is 21% quicker than Intel’s Core i7 8700K in the X264 stakes and 31% faster in Cinebench. It goes without saying then that it’s also evidently more powerful than the 1800X that topped the first-gen Ryzen range.

Now the bad news… it’s still well behind the Intel chip in terms of single-threaded performance. The 8700K is some 12% faster using the Cinebench index scores, partly down to the fact that it’s running with a higher frequency during testing.

That probably has you expecting the worst, thinking that despite how much effort AMD have put into making sure the Precision Boost 2 feature bumps the Ryzen 7 2700X’s all-core frequency it’s still going to be behind the Intel Coffee Lake CPU in terms of gaming performance. And you’d be right.

But here’s the thing, it doesn’t matter anymore. The bad news really isn’t that bad at all.

AMD Ryzen 7 2700X and Ryzen 5 2600X

It doesn’t matter because the difference in relative gaming performance is so minimal at 1080p that it will almost entirely disappear as soon as you push the resolution up above that level. At 1440p or 4K you’ll see nothing between the Ryzen 7 and Core i7 chips.

So now you finally have Ryzen genuinely competing in gaming performance at all levels, and massively outperforming the top Intel Coffee Lake chip in any computational task. And, what’s more, it does it for a good chunk less cash too.

What you will have to put up with, however, is the higher power draw of the Ryzen 7 2700X. With its 105W TDP you might expect it to draw more power too, and our testing highlights that. But that’s a modest problem, and arguably not a problem for most people who will happily jam a GPU into their rig that will double peak platform load in a second.

The big difference between Intel and AMD is still in the overclocking stakes. The Ryzen 7 2700X has been designed for higher frequencies out of the box, but it doesn’t have a lot of headroom if you want to take it any further. In fact, we only managed to get the all-core overclock to match the single-core max boost clock speed.

That’s a shame, but is also unlikely to be much of an issue for most people. The fact the 8700K can overclock stably to 5.2GHz all day long means it gets some bragging rights, but when it still  can’t keep up with the Ryzen 7 2700X’s processing chops, or give it any meaningful performance lead in games, it doesn’t really matter.

AMD Ryzen 7 2700X verdict

This makes Dave a happy panda. The Ryzen 7 2700X is a genuinely excellent high-end processor. I’m not just talking about it being a good value alternative, that it’s a decent CPU limited to productivity tasks, this is a great all-round processing monster of a chip. 

This is a processor that makes me question why anyone would now buy the 8700K instead. The Intel chip is more expensive, slower in computational tasks, and doesn’t offer any frame rate boost for you games. So why bother?

The Ryzen 7 2700X also has a more compelling overall package. The AM4 platform is going to last for at least the next two year, giving you somewhere to go if you decide to upgrade later on down the line, and the chip itself also comes with a quality CPU cooler out of the box too.

AMD Ryzen 7 2700X verdict

If you factor in that you might spend around $50 on a cooler for your Coffee Lake chip then we’re talking about it being around $70 cheaper than the 8700K. The only real issue for the Ryzen 7 2700X is that the 2600X is just as good on the gaming side and still has serious computational chops despite costing $100 less than the octacore chip. Intel are going to have to do something, because, with this pair, AMD are beating them.

The second-gen Ryzen chips prove that AMD have been listening, and the fact that they’ve managed to whisk out the lumps in the Ryzen batter (mmm, pancakes…) and get it to market in a little over a year is mighty impressive. It’s not just the 12nm chips which are lithe, the whole CPU side of the business seems to be too. They’ve been smart too holding back the inevitable Ryzen 7 2800X to combat whatever Intel can muster in response.

I’m not surprised AMD are taking some of the Zen brains over to fix whatever’s gone wrong on the graphics side of the business if this is what they come up with.

PCGamesN verdict: 8/10

I'm an AMD fan, currently have R5 1600 and waiting for my R7 2700X to be delivered.

With that said - your gaming results are hilarious - you've obviously hit a GPU bottleneck - there's not way all the se processors have almost the same average FPS on all titles, with 2-3 fps difference.

Also check your Hitman (DX12) results, how in hell can you have minimum FPS of 2-4 for all systems, yet 90+ average? Something has very wrong with your test there, and you should've double- and triple-checked that.

Well... this must be the most unreliable review I've ever seen... Specially gaming results make no sense... GPU botlleneck all the way... What a joke. You know that even a 7700k is able to crush a 2700x in gaming right? You should delete this article so you dont fool people.
