Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.

Storing multiple terabytes of video content monthly is, obviously, a drive-intensive business -- particularly when using RAID for local editing scratch disks, a NAS for internal server access, and web remote backup. Rather than buy more drives and build a data library that is both impossible to manage and impossible to search, we decided to use our disks smarter and begin compressing broll as it falls into disuse. Deletion is the final step, at some point, but the compression is small enough as to be a non-concern right now. We're able to compress our broll anywhere from 50-86%, depending on what kind of content is contained therein, and do so with nearly 0 perceptible impact to content quality. All that's required is a processor with a lot of threads, as that's what we wrote our compression script to use, and some extra power each month.

Threadripper saw use recently in a temporary compression rig for us, as we wanted to try the CPU out in a real-world use case for our day-to-day operations. The effort can be seen below:

Visiting AMD during the Threadripper announcement event gave us access to a live LN2-overclocking demonstration, where one of the early Threadripper CPUs hit 5.2GHz on LN2 and scored north of 4000 points in Cinebench. Overclocking was performed on two systems, one using an internal engineering sample motherboard and the other using an early ASRock board. LN2 pots will be made available by Der8auer and KINGPIN, though the LN2 pots used by AMD were custom-made for the task, given that the socket is completely new.

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.

This episode of Ask GN (#56) revisits the topic of AMD's Temperature Control (TCTL) offset on Ryzen CPUs, aiming to help demystify why the company has elected to implement the feature on its consumer-grade CPUs. The topic was resurrected with thanks to Threadripper's imminent launch, just hours away, as the new TR CPUs also include a 27C TCTL offset. Alongside this, we talk Threadripper CPU die layout diagrams and our use of dry erase marker (yes, really), sensationalism and clickbait on YouTube, Peltier coolers, Ivy Bridge, and more.

For a separate update on what's going on behind the scenes, our Patreon backers may be happy to hear that we've just posted an update on the Patreon page. The update discusses major impending changes to our CPU testing procedure, as Threadripper's launch will be the last major CPU we cover for a little while. Well, a few weeks, at least. That'll give us some time to rework our testing for next year, as our methods tend to remain in place for about a year at a time.

Following an initial look at thermal compound spread on AMD’s Threadripper 1950X, we immediately revisited an old, retired discussion: Thermal paste application methods and which one is “best” for a larger IHS. With most of the relatively small CPUs, like the desktop-grade Intel and AMD CPUs, it’s more or less been determined that there’s no real, appreciable difference in application methods. Sure – you might get one degree Centigrade here or there, but the vast majority of users will be just fine with the “blob” method. As long as there’s enough compound, it’ll spread fairly evenly across Intel i3/i5/i7 non-HEDT CPUs and across Ryzen or FX CPUs.

Threadripper feels different: It’s huge, with the top of the IHS measuring at 68x51mm, and significantly wider on one axis. Threadripper also has a unique arrangement of silicon, with four “dies” spread across the substrate. AMD has told us that only two of the dies are active and that it should be the same two on every Threadripper CPU, with the other two being branded “silicon substrate interposers.” Speaking with Der8auer, we believe there may be more to this story than what we’re told. Der8auer is investigating further and will be posting coverage on his own channel as he learns more.

Anyway, we’re interested in how different thermal compound spreading methods may benefit Threadripper specifically. Testing will focus on the “blob” method, X-pattern, parallel lines pattern, Asetek’s stock pattern, and AMD’s recommended five-point pattern. Threadripper’s die layout looks like this, for a visual aid:

Because of the spacing centrally, we are most concerned about covering the two clusters of dies, not the center of the IHS; that said, it’s still a good idea to cover the center as that is where the cooler’s copper density is located and most efficient.

Our video version of this content uses a sheet of Plexiglass to illustrate how compound spreads as it is applied. As we state later in the video, this is a nice, easy mode of visualization, but not really an accurate way to show how the compound spreads when under the real mounting force of a socketed cooler. For that, we later applied the same NZXT Kraken X62 cooler with each method, then took photos to show before/after cooler installation. Thermal testing was also performed. Seeing as AMD has permitted several other outlets to post their thermal results already, we figured we'd add ours to the growing pool of testing.

We moderate comments on a ~24~48 hour cycle. There will be some delay after submitting a comment.
