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.
As we work toward our inevitable hybrid mod on the nVidia Titan V, we must visit the usual spread of in-depth thermal, power, and clock behavior testing. The card uses a slightly modified Titan Xp cooler, with primary modifications found in the vapor chamber’s switch to copper heatfins. That’s the primary change, and not one that’s necessarily all that meaningful. Still, the card needs whatever it can get, and short of a complete cooler rework, this is about the most that can fit on the current design.
In this Titan V benchmark, we’ll be looking at the card’s power consumption during various heavy workloads, thermal behavior of the MOSFETs and GPU core, and how frequency scales with thermals and power. The frequency scaling is the most important: We’ve previously found that high-end nVidia cards leave noteworthy performance (>100MHz boost) on the table with their stock coolers, and suspect the same to remain true on this high-wattage GPU.
The nVidia Titan V is not a gaming card, but gives us some insights as to how the Volta architecture could react to different games and engines. The point here isn’t to look at raw performance in a hundred different titles, but to think about what the performance teaches us for future cards. This will teach us about the Volta architecture; obviously, you shouldn’t be spending $3000 to use a scientific card on gaming, but that doesn’t mean we can’t learn from it. Our tear-down is already online, but now we’re focusing on Titan V overclocking and FPS benchmarks, and then we’ll move on to production, power, and thermal content.
This nVidia Titan V gaming benchmark tests the Volta architecture versus Pascal architecture across DirectX 11, DirectX 12, Vulkan, and synthetic applications. We purchased the Titan V for editorial purposes, and will be dedicating the next few days to dissecting every aspect of the card, much like we did for Vega: Frontier Edition in the summer.
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.
Vega 64 may consume more power than a GTX 1080, but until now, we haven’t known if that impact is relevant to room temperature. That’s what we wanted to know, and we eventually expanded that concept to include how much a 900W+ mining machine increases room temperature, a 600W machine, and so on. We were able to effectively replace any need of a heater for the past week, and right when it started to get colder.
In this test, we’re looking at the room ambient impact of various PC builds. This helps to conceptualize the real-world impact of all those power and thermal tests you see us (and others) publish, as it puts real numbers to the user experience outside of the case. Although this concept has about a million variables and “what ifs,” we controlled to the best of our abilities, are laying-out all the major variables, and can present an academic experiment that demonstrates room temperature increase from computer equipment. All watts are basically created equal, for the purposes of this test: A 940W mining rig will output just as much heat into the room as a 940W gaming rig, or a 940W rendering machine, and so forth; as long as the power load is equal between all of these (read: constant), watts are watts, and you can extrapolate room temperature for each type of machine.
The testing originally was concepted after our Vega 56 Hybrid mod, which used power mods and other mods to push the card up towards 400W of power consumption. We wanted to test a straight Vega 56 versus GTX 1070 for room ambient impact, but shifted that up a tier (to Vega 64 and a GTX 1080) for some parts that are more likely to show a difference. After that, we shifted up to a 940W mining machine, then picked a middle-ground ~600W machine (which could also represent SLI gaming or HEDT render systems).
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!
