Amd Ryzen 7 2700x 8-core 37 Ghz Review
To say that AMD'south get-go-generation Ryzen family of desktop processors gave Intel's CPU sectionalisation a 20,000-volt wakeup telephone call would be the understatement of 2017. Now information technology'due south 2018, and AMD isn't content to simply poke its rival and run. With the Ryzen 7 2700X ($329), the Santa Clara chipmaker is ready for existent mano-a-mano fisticuffs with no gloves and no ref. This eight-core/16-thread flake builds on the success of the Ryzen 7 1800X and is a superb buy for budget-minded horsepower, and it'due south better situated in a more mature lath-and-chipset ecosystem, to boot. Coincidental ability users will detect information technology hard to top this CPU in terms of value.
The Fine art of Zen
The AMD Ryzen 7 2700X processor I'm testing features a iii.7GHz base of operations clock, a 4.3GHz maximum heave clock, and a 105-watt TDP. When you buy this processor in a retail package, you'll also get AMD's Wraith Prism CPU cooler, which features a copper core, direct-contact heatpipes, a quiet high-velocity fan, and customizable RGB LEDs. It's a very nice stock cooler, far more elegant than the usual Intel stock fare.

There's no on-die graphics nether this processor's heat spreader, so those looking to upgrade to this bit must plan on getting a discrete graphics card, likewise. Overclockers will likewise be relieved to learn that the Ryzen vii 2700X yet has a soldered-on heat spreader that's capable of shuttling heat away from the chip faster and more efficiently than the thermal interface fabric (TIM) between the die and heat spreader of Intel'due south flagship Core i7 processors. (Nobody de-lids AMD'south Ryzen processors.) Speaking of the Core i7-8700K, AMD is offering ii more cores and four more threads, for roughly $100 less than Intel'due south flagship. That's a adding difficult to ignore.
There's not a whole new compages to delve into with what AMD is calling the "Zen+," or "Pinnacle Ridge," refresh, just some tweaks here and there to address the starting time-generation processor'south main weaknesses. Furthermore, the Ryzen 7 2700X is built on Global Foundry's new 12nm Leading Operation (LP) FinFET manufacturing process, which is just a baby step forward compared to Zen'southward 14nm Low Power Plus (LPP) FinFET manufacturing process used in the Ryzen 7 thou-series chips. In improver to being designed specifically for existing 14nm architectures like Zen, the new process offers, AMD claims, 10 to 15 percent meliorate transistor performance. AMD also fabricated minor pattern adjustments to decrease the DRAM latencies by as much as 16 percent for the L1 and L3 caches, and upwards to 34 percent for the L2 cache. Overall, AMD estimates that there's a 3 pct jump in instructions per clock (IPC) between Zen and Zen+.
A More Granular Boost
AMD's latest processors yet have SenseMI automobile intelligence baked into the silicon, but the new Precision Boost 2 now gives the Ryzen vii 2700X the power to examine the electric current workload, factor in the cooling performance of the system, and dial those clock speeds higher, to the tune of between 300MHz and 500MHz (in 25MHz steps at a fourth dimension), depending on the task at hand. On the showtime-generation Ryzen processors, Precision Boost only actually fabricated a difference when ane or two cores were engaged. Even relatively lightweight workloads that used three cores or more than would force the clock speed of all cores to the slower "all cadre boost" state. With the 2000-series fries, Precision Boost two enables the clock speed to driblet off simply gradually as more cores are engaged, upwardly to the total eight.
All things considered, AMD designed Precision Boost two to exist relatively conservative. Notwithstanding, if yous're running a premium CPU cooler, such equally a closed-loop liquid cooler, the SenseMI algorithms can observe the improved thermal headroom. Extended Frequency Range 2 (XFR 2) is the clock-boosting characteristic that kicks into gear in these scenarios to deliver even higher frequencies under load. Information technology also works beyond every core and thread that's being pushed to the limit. AMD states that this feature alone tin can add another 7 percentage to the bit's operation.
Fifty-fifty though the Ryzen vii 2700X processor (and all Zen+ Pinnacle Ridge chips, for that matter) still piece of work in X370 motherboards, AMD also introduced a new characteristic to its X470 chipset and platform. I'm talking about AMD's StoreMI storage dispatch technology.
In short, the engineering intelligently shuffles your almost-used files to the fastest storage device in your system. For the vast majority of enthusiasts who have a mixed storage environs comprising one or more fast SSDs and high-capacity hard drives, this feature gives you lot the best performance experience across everything you exercise with your PC.
Precision Boost Overdrive, At Your Own Risk?
Precision Boost Overdrive was a feature that was but hinted at during the launch of the 2nd-generation Ryzen seven and 5 processors. At present that the Ryzen Threadripper 2990WX has been launched, withal, AMD has seen fit to explain this premium overclocking feature in greater item. Robert Hallock, Senior Technical Marketing Director at AMD, explains Precision Boost Overdrive in broad strokes in this video .
In brusque, the feature uses three parameters—temperature, power consumption from the CPU, and the VRM (your motherboard'south ability to supply power to the CPU)—to determine the how loftier the core frequency can climb before striking one or more than of these predefined limits. Traditional BIOS-based overclocking effectively moves these goalposts to give the processor more room to heave. Precision Heave Overdrive does exactly the aforementioned thing, but it's fully automatic. It requires a motherboard with a robust VRM, and it demands a better-than-stock CPU cooler, just like traditional overclocking. And, yep, information technology voids your warranty, also but like traditional overclocking.
If that'south not a primary business organization for you, then y'all'll exist happy to hear that enabling Precision Heave Overdrive can be done either from inside the BIOS of select X470 motherboards, or via a switch in AMD'due south Ryzen Primary overclocking utility, which y'all can download here .
One time the utility was downloaded and installed, I launched AMD Ryzen Master, switched to Creator Mode, clicked Precision Boost Overdrive, and and then clicked Utilize. When I enabled the feature, my Cinebench R15 score went from 175 (single cadre) and 1,777 (multicore) to 179 and ane,807 respectively. The MSI X470 Gaming M7 Air-conditioning motherboard has a Precision Boost Overdrive feature in the BIOS menu, and as of version 7B77v12, this warranty-voiding characteristic was, surprisingly, set to "Machine" by default.
Allow's Become Testing...
Earlier diving into my tried-and-true overclocking endeavors, I first ran our stock tests how this processor performs at its default settings, in a number of demanding desktop applications.
For my test setup, I installed the Ryzen 7 2700X into that MSI X470 Gaming M7 Ac motherboard, and populated ii of the DIMM slots with 16GB of dual-channel Crucial Ballistix Elite DDR4-3466 memory. For the kicking drive, I relied on the 500GB Samsung 850 EVO Thou.2 SATA SSD installed into the topmost M.two slot on this motherboard. I installed the components into the Phanteks Enthoo Pro Tempered Glass Edition example, with a Cooler Master MasterLiquid ML240L RGB closed-loop libation keeping my CPU temperatures in check. For the graphics menu, an MSI Radeon R9 290 Gaming 4G handled my display output.
To compare this processor's scores with other feasible options currently on the market, I included in the chart scores for the six-core/12-thread Intel Cadre i7-8700K mentioned earlier (the most direct Intel contest for this flake), as well every bit six-core six-thread Intel Cadre i5-8400, and the eight-core sixteen-thread Intel Core i7-7820X.
To represent the AMD side, I also worked in the viii-cadre sixteen-thread AMD Ryzen 7 1800X, the six-cadre 12-thread Ryzen 5 1600X, the vi-cadre 12-thread Ryzen v 2600X (I'1000 besides in the procedure of reviewing that bit), and for kicks and perspective, the 16-cadre/32-thread Ryzen Threadripper 2950X.
Cinebench R15
Maxon's 64-chip Cinebench R15 is a CPU-centric exam that lets me gauge both the unmarried-cadre and multicore performance of the various processors I tested. The resulting scores are proprietary numbers that represent the processor's performance while rendering a complex CPU-intensive image. This is considered a synthetic benchmark.
With its higher core count, it's no surprise that the AMD Ryzen vii 2700X bested the Core i7-8700K. The impressive feat was the Ryzen'southward besting of the Skylake Core i7-7820X processor from Intel'south Core X Serial, also. That said, the single-cadre functioning is all the same not quite up to par compared to Intel's best performers.
iTunes 10.6 Conversion Test
The iTunes x.6 Encoding Test, as good an example as you'll find hither of "legacy software," is laughably single-threaded, which means that more cores don't do AMD'due south fleck whatsoever favors. This exam is designed to illustrate the performance you might expect when running software yous just can't quit, but that doesn't scale well.
Although the Ryzen 7 2700X's higher clock speed helps information technology crush the first-gen Ryzen processors, Intel's processors have a distinct, though narrow, advantage.
Handbrake 0.9.9
Handbrake is a classic, and popular workstation utility that is used to catechumen video files between formats. Typically, the more threads and cores your processor has, the better it will perform in this application. I loaded upwardly a 12-infinitesimal 4K video clip titled Tears Of Steel and used the software to catechumen it into a 1080p MPEG-4 video.
In this real-world test, the Ryzen 7 2700X performed exceptionally well, lagging backside only one processor priced significantly higher, the mighty Threadripper 2950X, and essentially tying the pricier Core i7-7820X. If you do a lot of video editing, using applications that calibration well across multiple cores and threads, the Ryzen 7 2700X is a solid competitor.
POV-Ray 3.7
This benchmark is another one that'southward generally considered synthetic; still, the highly threaded nature of the utility is getting to be more and more representative of the applications bachelor today. I ran POV-Ray using both the multi-threaded "All CPUs" setting and the hamstrung "One CPU" setting. The benchmark tasks the processor with rendering a complex photograph-realistic prototype using ray tracing.
Only the 16-core Threadripper beat the Ryzen 7 2700X when the processor was fully unleashed. When limited to a single cadre, however, AMD's processor performs well but lags behind the more expensive Intel Coffee Lake and Skylake chips. It's interesting to note that the Intel Core i5-8400 is significantly slower, due to that chip's lower clock speed and lack of support for Hyper-Threading.
Blender 2.77a
Some other of the real-globe benchmarks used here is Blender, a popular open up-source 3D rendering application that people far more creative and talented than I use to craft 3D visual effects, animations, and models. Our test file consists of a cartoonish flying-squirrel render that takes less than a minute to complete with most modern processors.
Blender was ane of the offset-gen Ryzen's weakest benchmarks, and here, it'due south clear that the new surreptitious sauce in the Ryzen 7 2700X, in addition to this processor's higher clock speed, has helped information technology proceeds ground. Intel's flagship still has a slight edge, though.
7-Zippo File Pinch
vii-Nil is a widely used file-compression utility that features a built-in compression/decompression benchmark. It is a existent-world test that generally utilizes as many cores and threads as your processor has to offer.
Here again, it's clear: When the awarding can handle multiple cores, the Skylake Core i7-7820X and Threadripper 2950X are the only chips that score better than the Ryzen 7 2700X in this lot. When you expect at the performance leap from the Ryzen seven 1800X to the Ryzen 7 2700X (two processors with the same core and thread count) the improvement between the outset-generation and 2d-generation Ryzen chips comes into sharp focus. And here, AMD manages to leapfrog Intel's flagship Coffee Lake processor.
Ryzen Gaming, Revisited
When the offset-generation Ryzen processors debuted, Intel's contemporary crop of chips consistently beat them in one specific application: gaming at 1080p. With modernistic games, midrange and loftier-terminate discrete graphics cards barely break a sweat at this resolution, forcing the processor to perform a lot of the heavy lifting. Information technology's not a new problem, but Intel's decade of authorisation has afforded the company's processors countless generation-on-generation game optimizations. Ryzen had none of those inherited optimizations when information technology launched, and as a consequence, Intel's processors were enjoying significant and noticeable frame rate advantages across a range of popular games. The problem was much less pronounced at 1440p and all merely nonexistent at 4K, only it was enough for many low-resolution gamers to write off Ryzen.
Fast-frontward to today. Does the Ryzen 7 2700X suffer from the same problems? Based on some limited gaming testing we've performed, things are much better this time around, just AMD nonetheless hasn't achieved complete parity with Intel in some games. Final twelvemonth, when running Far Cry Primal (on the Loftier preset) at 1080p, AMD's flagship Ryzen 7 1800X processor paired with a GeForce GTX 1080 Founders Edition card scored an average of 84fps for the elapsing of the built-in criterion.
The same examination, with the same discrete graphics card and the new Ryzen 7 2700X, yielded 105fps, for a 25 percent increment. Intel's Core i7-8700K scored 138fps, so Intel's advantage is nevertheless evident, fifty-fifty if you'd be hard-pressed to notice it most of the time, given such high averages.
Rise Of The Tomb Raider (tested at DX11, on the Very High preset), on the other hand, showed no frame-charge per unit increase between the one-time and new Ryzen processors, though Intel still showed a roughly 20 percent reward at 1080p.
At 4K, all systems performed nearly identically (within one or two frames per second), as you'd wait most systems to when equipped with the aforementioned discrete graphics card. My advice for PC gamers is less to avoid Ryzen and more than to invest in a higher-resolution, high-refresh-rate, or ultra-broad monitor to go with your uber-powerful graphics card. Under nigh circumstances, the rest is hair-splitting.
Overclocking
At first, I overclocked the Ryzen seven 2700X using the BIOS on the MSI X470 Gaming M7 Ac. This method involved slightly raising the core frequency, testing for stability, raising it again, and testing for stability once again until the organization fails to boot or becomes unresponsive, then systematically raising the core voltage until stability is once again achieved. All the while, I kept an centre on the processor'due south core temperature under load to make sure our Libation Master MasterLiquid ML240L RGB closed-loop cooler was keeping up with the heat output. Like on all Ryzen processors, the multiplier on the Ryzen 7 2700X is fully unlocked, making reliable overclocking fairly straightforward.
I managed to go Windows stable plenty to run Cinebench R15 while the Ryzen 7 2700X was clocked (all-cores) at iv.4GHz, four.35GHz, and 4.325GHz, but I encountered stability problems at all speeds in Handbrake. The highest score I ever got in Cinebench was 1,965 (all cores) and 181 (single core), but to get results in the rest of the tests, I had to back off. In the motherboard's BIOS menu, leaving the CPU voltage gear up to "Machine" actually produced the most consistently stable experience, and my highest reliable scores were achieved with the core speed fix to four.3GHz. I also fiddled with a few other settings in the BIOS, such as the CPU Loadline Scale modes, and I tried small tweaks to the CPU Base Clock, with express success.
Although I saw good increases across the benchmarks, it'southward important to go along in mind that I was using an all-in-one liquid cooler, which performs better than the Wraith Cooler that AMD ships with this processor. Although 4.3GHz was rarely achievable for the first-generation Ryzen processors, information technology appears as though the Ryzen 7 2000 series tin reach such heights with minimal effort. Safely going beyond that clock speed, fifty-fifty by a little bit, seems unlikely without some grade of exotic cooling.
I also tried overclocking using Precision Boost Overdrive in the Ryzen Master utility, and was pleasantly surprised at how close the results came to our manual overclocking scores. If overclocking in the BIOS is intimidating, and the threat of losing warranty coverage doesn't faze yous, and then I endorse unleashing PBO in Ryzen Main. Information technology'due south an easy, effective way to eke out some extra functioning from your Ryzen 7 2700X processor.
Verdict? Eight's Plenty for Nearly of United states
With the 2nd-generation Ryzen processors, AMD has proven that the Zen architecture was much more than but a flash in the pan. This is a blueprint with legs, and given the recently launched second-generation Threadripper processors, those legs are very long indeed.
If there'due south 1 positive thing we tin accept away from the decade of lackluster processor launches from AMD pre-2017, information technology is that the company has consistently offered more than for less. Now that Ryzen is competitive with Intel's current flagship processor, however, the more-for-less proposition is extra-compelling, whether you're a gamer, a professional, or simply an enthusiast who loves to run across the underdog come out on pinnacle now and again. This underdog is rapidly evolving into an alpha dog.

AMD Ryzen seven 2700X
The Bottom Line
AMD's eight-core Ryzen 7 2700X shines for workstation apps and multitasking, and gamers who pair information technology with a high-end video menu should become better 1080p gaming than with offset-gen Ryzen. That'south a winning combo.
