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.

This week's hardware news recap covers rumors of Corsair's partial acquisition, HBM2 production ramping, Threadripper preparation, and a few other miscellaneous topics. Core industry topics largely revolve around cooler prep for Threadripper this week, though HBM2 increasing production output (via Samsung) is also a critical item of note. Both nVidia and AMD now deploy HBM2 in their products, and other devices are beginning to eye use cases for HBM2 more heavily.

The video is embedded below. As usual, the show notes rest below that.

Every now and then, a content piece falls to the wayside and is archived indefinitely -- or just lost under a mountain of other content. That’s what happened with our AMD Ryzen pre-launch interview with Sam Naffziger, AMD Corporate Fellow, and Michael Clark, Chief Architect of Zen. We interviewed the two leading Zen architects at the Ryzen press event in February, had been placed under embargo for releasing the interview, and then we simply had too many other content pieces to make a push for this one.

The interview discusses topics of uOp cache on Ryzen CPUs, power optimizations, shadow tags, and victim cache. Parts of the interview have been transcribed below, though you’ll have to check the video for discussion on L1 writeback vs. writethrough cache designs and AMD’s shadow tags.


“Good for streaming” – a phrase almost universally attributed to the R7 series of Ryzen CPUs, like the R7 1700 ($270 currently), but with limited data-driven testing to definitively prove the theory. Along with most other folks in the industry, we supported Ryzen as a streamer-oriented platform in our reviews, but we based this assessment on an understanding of Ryzen’s performance in production workloads. Without actual game stream benchmarking, it was always a bit hazy just how the R7 1700 and the i7-7700K ($310 currently) would perform comparatively in game live-streaming.

This new benchmark looks at the AMD R7 1700 vs. Intel i7-7700K performance while streaming, including stream output/framerate, drop frames, streamer-side FPS, power consumption, and some brief thermal data. The goal is to determine not only whether one CPU is better than the other, but whether the difference is large enough to be potentially paradigm-shifting. The article explores all of this, though we’ve also got an embedded video below. If video is your preferred format, consider checking the article conclusion section for some additional thoughts.

Specs and prices for AMD’s upcoming Ryzen Threadripper CPUs have been announced, as well as a general release date. The 12C/24T 1920X and 16C/32T 1950X will be available worldwide starting in “Early August,” with prebuilt Alienware systems available for preorder starting July 27th. According to AMD:

“Both are unlocked, use the new Socket TR4, have quad-channel DDR4, and feature 64 lanes of PCI Express. Base clock on the Ryzen Threadripper 1950X 16-core product is 3.4 GHz with precision boost to 4.0 GHz. On the Ryzen Threadripper 1920X 12-core product, the base clock is 3.5 GHz with precision boost to 4.0 GHz.”

As an aside, manufacturers informed GamersNexus at Computex that board release dates are targeted for August 10. It’s possible that this date has changed in the time since the show, but that seems to be the known target for Threadripper.

This week's hardware news recap primarily focuses on industry topics, like new NAND from Toshiba, Western Digital, and a new SSD from Intel (first 64-layer VNAND SSD). A few other topics sneak in, like AMD's Ryzen Pro CPU line, a Vega reminder (in the video), the death of Lexar, and a few gaming peripherals.

Through the weekend, we'll be posting our Zotac 1080 Ti Amp Extreme review, the first part of our AMD Vega: Frontier Edition Hybrid mod, and a special benchmark feature in our highly acclaimed "Revisit" series.

In the meantime, here's the last week of HW news recapped:

Following AMD’s Computex press conference, we headed over to the Gigabyte suite (after our X299 coverage) to look at the X399 Aorus Gaming 7 motherboard. The new Gigabyte X399 Gaming 7 board is one of two that we’ve seen thus far – our ASUS coverage is next up – and joins the forces of motherboards ready for AMD’s Threadripper HEDT CPUs.

The Gigabyte X399 Aorus Gaming 7 motherboard sockets Threadripper into AMD’s massive socket, dead-center, and uses three Torx screws to get at the LGA pin-out. The CPUs will provide 64 PCIe lanes, as we’ve already reported, with 4x PCIe Gen3 lanes reserved for high-speed transport between the CPU and chipset. The other 60 are assignable at the motherboard manufacturer’s will; in this case, Gigabyte willed for an x16/x8/x16/x8 full-length PCIe slots, with an additional 3x M.2 (x4) slots. That immediately consumes all 60 lanes, with the remaining 4 reserved for the chipset communications.
