In the calm before the global celebration of consumerism, it would seem that the entire range of AMD processors has gone on sale – or most of it, anyway. Several of these have tempted us for internal machines, at this point. The Threadripper 1950X has been available as low as $800 (from the usual $1000) price-point, the R7 CPUs are cut into R5 prices -- $260 for the 1700X is now common, and R5 CPUs have also been dropping in price. The timing is excellent, too, as we just posted our Best CPUs of 2017 Awards, which include several of these sale items.
Enermax's Liqtech TR4 liquid cooler took us by surprise in our 240mm unit review, and again in our Liqtech 360 TR4 review. The cooler is the first noteworthy closed-loop liquid cooler to accommodate Threadripper, and testing proved that it's not just smoke and mirrors: The extra coldplate size enables the Liqtech to overwhelm any of the current-market Asetek CLCs, which use smaller coldplates that are more suitable to Ryzen or Intel CPUs.
The Windows 10 Fall Creators Update (FCU) has reportedly provided performance uplift under specific usage scenarios, most of which center around GPU-bound scenarios with Vega 56 or similar GPUs. We know with relative certainty that FCU has improved performance stability and frametime consistency with adaptive synchronization technologies – Gsync and FreeSync, mostly – and that there may be general GPU-bound performance uplift. Some of this could come down to driver hooks and implementation in Windows, some of it could be GPU or arch-specific. What we haven’t seen much of is CPU-bound tests, attempting to isolate the CPU as the DUT for benchmarking.
These tests look at AMD Ryzen R7 1700 (stock) performance in Windows 10 Creator’s Update (build 1703, ending in 608) versus Windows 10 Fall Creators Update. Our testing can only speak for our testing, as always, and we cannot reasonably draw conclusions across the hardware stack with these benchmarks. The tests are representative of the R7 1700 in CPU-bound scenarios, created by using a GTX 1080 Ti FTW3. Because this is a 1080 Ti FTW3, we have two additional considerations for possible performance uplift (neither of which will be represented herein):
- - As an nVidia GPU, it is possible that driver/OS behavior will be different than with an AMD GPU
- - As a 1080 Ti FTW3, it is possible and likely that GPU-bound performance – which we aren’t testing – would exhibit uplift where this testing does not
Our results are not conclusive of the entirety of FCU, and cannot be used to draw wide-reaching conclusions about multiple hardware configurations. Our objective is to start pinpointing performance uplift, and from what combination of components that uplift can be derived. Most reports we have seen have spotted uplift with 1070 or Vega 56 GPUs, which would indicate GPU-bound performance increases (particularly because said reports show bigger gains at higher resolutions). We also cannot yet speak to performance change on Intel CPUs.
Hardware news for the last week includes discussion on an inadvertent NZXT H700i case unveil (with “machine learning,” apparently), Ryzen/Vega APU, Vega partner card availability, and Coffee Lake availability.
Minor news items include the AMD AGESA 126.96.36.199 update to support Raven Ridge & Pinnacle Ridge, Noctua’s Chromax fans, and some VR news – like Oculus dropping its prices – and the Pimax 8K VR configuration.

This episode of Ask GN was filmed a few days ago, but we ended up with so much content (like the H500P review and Vega 64 Strix PCB analysis) that we postponed its publication. The episode tackles popular topics of thermals and thermal testing, which have recently received more public interest, and also covers some top-level discussion of power, thermals, and electricity.
We spend most of the time discussing motherboard differences -- a story we've been harping on since January -- and how different board voltages affect CPUs in different ways. The rest of the intro is spent explaining thermal testing difficulties and challenges, and how we can best normalize for those in review content. The timestamps are below the video embed:
No surprise in that headline, really.
Some of this information is rehashed, but has been bulked-up by alleged AMD slides leaked to Informatica Cero. The slides, which are functionally in “rumor” status, indicate AMD’s code-named Matisse processors as launching in 2019. The Matisse CPUs will carry AMD’s Zen 2 architecture, but aim to continue supporting AM4 platforms. Before that launch, AMD’s Zen Plus iteration is targeted for 2018, allegedly, and will exist primarily as an optimization on the existing Ryzen CPUs. This can be thought of as an analog to the retired Intel tick-tock cadence, with Zen Plus likely targeting frequency tuning.
The launch of Threadripper marks a move closer to AMD’s starting point for the Zen architecture. Contrary to popular belief, AMD did not start its plans with desktop Ryzen and then glue modules together until Epyc was created; no, instead, the company started with an MCM CPU more similar to Epyc, then worked its way down to Ryzen desktop CPUs. Threadripper is the fruition of this MCM design on the HEDT side, and benefits from months of maturation for both the platform and AMD’s support teams. Ryzen was rushed in its weeks leading to launch, which showed in both communication clarity and platform support in the early days. Finally, as things smoothed-over and AMD resolved many of its communication and platform issues, Threadripper became advantaged in its receipt of these improvements.
“Everything we learned with AM4 went into Threadripper,” one of AMD’s representatives told us, and that became clear as we continued to work on the platform. During the test process for Threadripper, work felt considerably more streamlined and remarkably free of the validation issues that had once plagued Ryzen. The fact that we were able to instantly boot to 3200MHz (and 3600MHz) memory gave hope that Threadripper would, in fact, be the benefactor of Ryzen’s learning pains.
Threadripper will ship in three immediate SKUs:
Respectively, these units are targeted at price-points of $1000, $800, and $550, making them direct competitors to Intel’s new Skylake-X family of CPUs. The i9-7900X would be the flagship – for now, anyway – that’s being more heavily challenged by AMD’s Threadripper HEDT CPUs. Today's review looks at the AMD Threadripper 1950X and 1920X CPUs in livestreaming benchmarks, Blender, Premiere, power consumption, temperatures, gaming, and more.
Our recent R7 1700 vs. i7-7700K streaming benchmarks came out in favor of the 1700, as the greater core count made it far easier to handle the simultaneous demands of streaming and gameplay without any overclocking or fiddling with process priority. Streaming isn’t the whole story, of course, and there are many situations (i.e. plain old gaming) where speed is a more valuable resource than sheer number of threads, as seen in our original 1700 review.
Today, we’re testing the R7 1700 and i7-7700K at 1440p 144Hz. We know the i7-7700K is a leader in gaming performance from our earlier CPU-bottlenecked 1080p testing; that isn’t the point here. We’ve also pitted these chips against each other in VR testing, where our conclusion was that GPU choice mattered far more, since both CPUs can deliver 90FPS equally well (and were effectively identical). This newest test is less of a competition and more of a “can the 1700 do it too” scenario. The 1700 has features that make it attractive for casual streaming or rendering, but that doesn’t mean customers want to sacrifice smooth 144Hz in pure gaming scenarios. As we explain thoroughly in the below video, there are different uses for different CPUs; it’s not quite as simple as “that one’s better,” and more accurately boils down to “that one’s better for this specific task, provided said task is your biggest focus.” Maybe that’s the R7 1700 for streaming while gaming, maybe that’s the 7700K for gaming -- but what we haven’t tested is if the 1700 can keep up at 144Hz with higher quality settings. We put to test media statements (including our own) that the 1700 should be “better at streaming,” finding that it is. It is now time to put to test the statements that the 7700K is “better at 144Hz” gaming.
This series is an ongoing venture in our follow-up tests to illustrate that, yes, the two CPUs can both exist side-by-side and can be good at different things. There’s no shame in being a leader in one aspect but not the other, and it’s just generally impossible given current manufacturing and engineering limitations, anyway. The 7700K was the challenger in the streaming benchmarks, and today it will be challenged by the inbound R7 1700 for 144Hz gaming.
People like to make things a bloodbath, but just again to remind everyone: This is less of a “versus” scenario and more of a “can they both do it?” scenario.
AMD’s Ryzen lineup mirrors traits at both the R3 and R7 ranges, where both series of CPUs are effectively the same inter-lineup, but with different clock speeds. The R7 CPUs largely all clock to about the same area (+/-200MHz) and consist of the same features. The same can be said for the two R3 SKUs – the R3 1200 and R3 1300X – where the CPUs are functionally identical outside of frequency. This means that, like with the R7 1700, the R3 1200 has potential to challenge and replace the 1300X for users willing to overclock. Remember: A basic overclock on this platform is trivial and something we strongly encourage for our audience. The cost savings are noteworthy when driving an R7 1700 up to 1700X or 1800X levels, and the same can likely be said about the R3 1200.
That’s what we’re finding out today, after all. Our R3 1200 review follows the review of the 1300X and aims to dive into gaming performance, overclocking performance, production applications, and power consumption. Nearby CPUs of note include the 1300X, the Pentium G4560, the R5 series CPUs, and the i3 CPUs.
AMD’s R3 1200 is a $110 part, making it $20 cheaper than the R3 1300X and significantly cheaper than both the i5 and R5 CPUs. Frequency is also down: The R3 1200 clocks at 3.1GHz base / 3.4GHz boost on its 4C/4T design, lower than the R3 1300X that we just reviewed.
The Ryzen 3 CPUs round-out AMD’s initial Ryzen offering, with the last remaining sector covered by an impending Threadripper roll-out. Even before digging into the numbers of these benchmarks, AMD’s R3 & R5 families seem to have at least partly influenced competitive pricing: The Intel i3-7350K is now $150, down from its $180 perch. We liked the 7350K as a CPU and were excited about its overclocking headroom, but found its higher price untenable for an i3 CPU given then-neighboring i5 alternatives.
Things have changed significantly since the i3-7350K review. For one, Ryzen now exists on market – and we’ve awarded the R5 1600X with an Editor’s Choice award, deferring to the 1600X over the i5-7600K in most cases. The R3 CPUs are next on the block, and stand to challenge Intel’s freshly price-reduced i3-7350K in budget gaming configurations.
