Hardware

This episode of Ask GN, shipping on Christmas day, answers a few pertinent questions from the last few weeks: We'll talk about whether we made ROI on the Titan V, whether it makes more sense to buy Ryzen now or wait for Ryzen+/Ryzen2, and then dive into the "minor" topics for the segment. Smaller topics include discussion on choosing games for benchmarking -- primarily, why we don't like ROTTR -- and our thoughts on warranty/support reviews, with some reinforced information on vertical GPU mounting. The conclusion focuses on an ancient video card and some GN modmat information.

Refilling an AIO with New Fluid - Thermal Test Results

By Published December 23, 2017 at 11:31 pm

We previously went through the process of dismantling, draining, and refilling an Enermax Liqtech TR4 closed-loop liquid cooler (some call these "AIOs") in an attempt to determine how serviceable the CLCs are. This particular cooler wasn't too difficult to refill, as we showed in our accompanying video, but we still wanted to check thermal results to see if the cooler had worsened in performance. The goal wasn't to make it better, just to see if it could be serviced, and without negative impact to cooling ability.

Keep in mind that fluid selection will matter: If the CLC mixes metals, as many do, you'll want to include a biocide of some sort in your refill. There are plenty of mixtures that would achieve this. We used an EK Cryofuel with biocide additive, with distilled water as the primary component (>90%) for the liquid composition. Our thermal test methodology is the same as in all our Threadripper cooler reviews, including the Enermax 360 vs 240 review. If curious how we tested, head over there.

HW News: 1Q18 Ryzen+, EK Executives Join Corsair

By Published December 18, 2017 at 10:46 pm

This week's hardware news recap diverges from Titan V coverage and returns to some normalcy, sort of, except the joining of Corsair by former top EK executives. We also have some loose confirmation of Ryzen+ for 1Q18, MSI's new RX Vega 64 Air Turbo card, and Sapphire's Nitro+ Vega 64 card. Still lots of AMD news, it seems, though Intel popped-up with Gemini Lake, if briefly.

NVIDIA Titan V Tear-Down & PCB: Bare GPU Look at Volta

By Published December 11, 2017 at 11:56 pm

After completing all of our gaming, power, thermal, and other benchmarks for the new nVidia Titan V graphics card, we took the unit apart for cooler, PCB, and VRM analysis. We’ll be joined by overclocker ‘Buildzoid’ in the next few days for the advanced overclocking analysis of the PCB and VRM, but have some immediate information on the assembly of the Titan V and its cooler.

The card follows the same screw pattern as all previous nVidia Founders Edition cards, including the Titan Xp and GTX 1080, primarily isolating its cooler and shroud into a single, separable unit. Build materials are all the same, assembly is the same, but the underlying GPU, HBM2, VRM, and heatsink are different.

Ask GN: Buy or Wait for Volta?

By Published December 09, 2017 at 4:15 pm

This episode of Ask GN headlines with answering the most common question we’ve seen in the past 24 hours: Should I buy now or wait for Volta? That’ll start us off for this episode, followed by clarification of VRM quality, a history lesson on AM4 motherboards at launch and HIS existence, and silicon death from overclocking. This episode runs about 25 minutes, with each question timestamped within the video. We also have the timestamps and questions marked below, if you’d like to see when a particular topic of interest appears.

The Volta topic, we think, is among the most interesting and common for questions right now. This seems to come around for every new architecture, and our answers are generally the same. Find out more below!

NVidia introduced its new Titan V GPU, which the company heralds as the “world’s most powerful GPU for the PC.” The Titan V graphics card is targeted at scientific calculations and simulation, and very clearly drops any and all “GTX” or “gaming” branding.

The Titan V hosts 21.1B transistors (perspective: the 1080 Ti has 12B, P100 has 15.3B), is capable of driving 110TFLOPS of Tensor compute, and uses the Volta GPU architecture. We are uncertain of the lower level specs, and do not presently have a block diagram for the card. We have asked for both sets of data.

Thermaltake Core P90 Chassis Gets Abstract

By Published November 30, 2017 at 8:14 pm

“Chassis” is pretty loose, here. The Thermaltake Core P90 follows the Core P3 and Core P5 lines, but only insofar as being an open air, semi-exposed bench-style “case.” It’s more of a mounting board for parts, really, and presents them in a triangular layout, the board and VGA on flanking sides.

The case includes 2x 5mm tempered glass side panels (though we think it might be a decent bench platform without the glass), mounts the power supply within the central frame, and is dotted with cable routing holes on both component-hosting panels. This case remains wall-mountable, just like its P3 and P5 successors, though may be a bit unwieldy to get onto the stud mounts, if for no other reason than radiator support up to 480mm. That’s a lot of liquid to hang on the wall.

This week’s hardware news recap covers major AMD Ryzen CPU sales (read more here), Intel Optane Xpoint DIMMs, new fabs spinning-up for Coffee Lake production, and more. Not covered in this news recap is the Gigabyte BIOS security push for Intel’s vulnerabilities and the FCC regulations (or lack thereof). You can learn more about those at the respective links.

Supporting news items for the week include Samsung Z-NAND, CaseLabs’ SMA8, FireFox Quantum, and more.

As usual, the show notes are below the embedded video.

Intel Optane Memory Modules in 2018

By Published November 19, 2017 at 11:53 am

During a presentation at the USB Global Technology Conference, Intel indicated that the roadmap for Intel Optane DIMMs lands their proprietary memory somewhere in the second half of 2018. Thus far, we’ve seen the storage and caching side of Intel Optane 3D XPoint. It seems in 2018, we’ll be afforded the opportunity to witness 3D XPoint as main memory.

NVIDIA’s Battlefront II Game Ready driver version 388.31 shipped this week in preparation for the game’s worldwide launch. In possibly more positive news for the vast number of redditors enraged by EA’s defense of grinding, the driver is also updated for Injustice 2 compatibility and boasts double-digit % performance increases in Destiny 2 at higher resolutions.

Battlefront 2 is the headliner for this driver release, but this chart is about all NVIDIA has to say on the subject for now:

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