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.
This episode of Ask GN returns with our new format, frontloading the episode with some discussion topics before feeding into the user-submitted questions. As always, for consideration in next episode, please leave your comment on the YouTube playback page or in our Ask GN Discord channel for Patreon backers.
The video opens with another “gift” from NZXT, some new power draw testing, AMD Vega naming thoughts (and rushed launches with Intel & AMD), and then addresses user questions. We hop around from liquid metal to CPU and airflow topics, giving a good spread to this episode.
Watch below – timestamps below the embedded video:
Zotac's GTX 1080 Ti AMP! Extreme is one of the largest GTX 1080 Ti cards on the market, rivaling the Gigabyte Aorus Xtreme card in form factor. The card uses nearly three expansion slots, runs a long PCB and cooler, and hosts a dense aluminum heatsink with a three-fan cooler. This card runs $750 to $770, depending on if the “Core” edition is purchased. The only difference is the out-of-box clock, but all these 1080 Tis perform mostly the same in games (once solving for thermals).
For its VRM, Zotac takes a brute-force approach to the 1080 Ti, using a doubled-up 8-phase (16 phases total) with rebranded QN3107 and QN3103 MOSFETs, operating on a UP9511 in 8-phase mode. The VRM is the reason for the tall card, with two phases tucked off to the side (under a small aluminum heatsink that's isolated from all other cooling). This theoretically helps distribute the heat load better across a larger surface area, which Zotac then cools using a small aluminum fin stack that's isolated from the denser aluminum fin array. Above the VRM's isolated heatsink rests a rubber damper, which doesn't fully make contact (and is presumably to prevent scratching in the event of over-flex during installation, as it otherwise does nothing), and then the three fans.

The card is one of the heaviest, largest cards we've looked at this generation. To give some perspective, Zotac's AMP Extreme is about 1” thicker than a 2-slot card (like the reference card), is longer than the Aorus Xtreme, and is heavy from the mass of aluminum resting atop the GPU. Learn more about the inner-workings of this card in our tear-down.
For today, we're focusing on thermals, power, and noise, as that's the biggest difference between any of these 1080 Ti cards. The gaming performance and overclocking performance, sans Kingpin/Lightning cards, is not notably different.
We’ve already endured one launch of questionable competence this quarter, looking at X299 and Intel’s KBL-X series, and we nearly escaped Q2 without another. Vega: Frontier Edition has its ups and downs – many of which we’ll discuss in a feature piece next week – but we’re still learning about its quirks. “Gaming Mode” and “Pro Mode” toggling is one of those quirks; leading into this article, it was our understanding – from both AMD representatives and from AMD marketing – that the switch would hold a relevant impact on performance. For this reason, we benchmarked for our review in the “appropriate” mode for each test: Professional applications used pro mode, like SPECviewperf and Blender. Gaming applications used, well, gaming mode. Easy enough, and we figured that was a necessary methodological step to ensure data accuracy to the card’s best abilities.
Turns out, there wasn’t much point.
A quick note, here: The immediate difference when switching to “Gaming Mode” is that WattMan, with all its bugginess, becomes available. Pro Mode does not support WattMan, though you can still overclock through third-party tools – and probably should, anyway, seeing as WattMan presently downclocks memory to Fury X speeds, as it seems to have some leftover code from the Fury X drivers.
That’s the big difference. Aside from WattMan, Gaming Mode technically also offers AMD Chill, something that Pro Mode doesn’t offer a button to use. Other than these interface changes, the implicit, hidden change would be an impact to gaming or to production performance.
Let’s briefly get into that.
Reader and viewer requests piled high after our Vega: Frontier Edition review, so we pulled the most popular one from the stack to benchmark. In today’s feature benchmark, we’re testing Vega: FE vs. the R9 Fury X at equal core clocks, resulting in clock-for-clock testing that could be loosely referred to as an “IPC” test – that’s not exactly the most correct phrasing, but does most quickly convey the intent of the endeavor. We’ll use the phrase “academic exercise” a few times in this piece, as it’s difficult to draw strong conclusions to other Vega products from this test; ultimately, GPUs simply have too many moving parts to simulate easier IPC benchmarks like you’d find on a CPU. As one limitation is resolved, another emerges – and they’re likely different on each architecture.
Regardless, we’re testing the two GPUs clock for clock to see how Vega: FE responds with the Fury X in the ring.
Toshiba just announced its QLC (Quad-Level Cell) NAND flash, something we talk about in our upcoming news video, and has further claimed that the new 96GB (768Gb) units will compete with TLC NAND in total program/erase endurance. This is Toshiba’s new 64-layer NAND that hasn’t yet made it into consumer products, but likely will make the move within the next year. Like TLC, QLC increases the count of voltage states (now 16) to increase the bits per cell, thereby increasing storage capacity per cell.
