One of the most requested additions to our video card testing has been to normalize for noise. Several of you have emailed, tweeted, or tagged us on Reddit to ask for this type of testing, and so we started the process of re-testing some devices to build a database. The idea is to find fan RPM at a fixed dBA output – 40dBA, for example – and then test thermal performance when fans match that noise level. This doesn’t take into account the type of noise, e.g. frequency spectrum analysis, but it’s a good start to a new type of testing. And, honestly, most of these coolers sound about the same pitch/frequency (subjectively) with regard to frequency output.
The ASUS ROG Strix 1080 Ti review is our first to introduce normalized noise testing, and it’s an interesting card to start us off. We’ll talk more about that specific testing approach lower down.
Silverstone’s RL06 case is divided into four SKUs: SST-RL06BR and SST-RL06WS, with -W and -PRO versions of both. Our review sample is the SST-RL06WS-PRO ($75), which means it’s white with silver trim (WS) and comes with 3x 120mm white LED fans (PRO). BR is black with red trim, and -W is theoretically exactly the same case without the fancy fans, although there don’t appear to be any available anywhere right now.
The RL06 is a stripped-down case with serious airflow at a budget price. Today, we’re putting it on our bench against the nearby Corsair 270R, Be Quiet Pure Base 600, Fractal Define C, and other options we’ve tested recently. The RL06 is more airflow-focused than noise-focused, giving us something different to analyze than the past few case reviews.
Intel’s i3/i5/i7 and AMD’s R5/R7 CPUs are the big competitors in the PC gaming world, but they aren’t the only options out there: AMD released cheap but capable Athlon X4s in 2016, and in January of this year Intel released the 2C/4T Pentium G4560 ($70), a 14nm Kaby Lake processor for ~$64~$70. We didn’t fully review the older and (briefly) popular Pentium G3258, but it has showed up in Ask GN and individual benchmarks, so we were excited to do comprehensive testing on this modern iteration.
The G4560 lacks the feature that made the G3258 so popular: the ability to overclock. Buying a dirt-cheap dual-core processor and cranking the frequency up was enough for decent performance in limited-thread games, although the G3258 often suffers from extreme stuttering in more modern titles. The limitations lead us to believe that Intel doesn’t want to compete with its own more expensive 2C/4T unlocked i3 and locked i3-7100 ($120) & 7300 ($150).
The EVGA GTX 1080 Ti FTW3 is the company’s attempt at a 3-fan cooler, entering EVGA into the three-fan ranks alongside ASUS, Gigabyte, and MSI. The difference with EVGA’s card, though, is that it’s a two-slot design; board partners have gone with a “bigger is better” mentality for the 1080 Ti, and it’s not necessarily advantageous. Sure, there are benefits – taller cards mean taller fans, like on the Gaming X, which results in slower rotation of fans without sacrificing volume of air moved. It follows then that taller fans on taller cards could be profiled to run quieter, without necessarily sacrificing thermal performance of the GPU, VRM, and VRAM components.
But we’re testing today to see how all that plays out in reality. In our EVGA GTX 1080 Ti FTW3 review, we benchmark the card vs. EVGA’s own SC2, MSI’s 1080 Ti Gaming X, Gigabyte’s Xtreme Aorus, and the Founders Edition card. Each of these also has an individual review posted, if you’re looking for break-outs on any one device. See the following links for those (listed in order of publication):

It’s Not About Gaming Performance
Having reviewed this many cards in the past few weeks, it should be apparent to everyone that same-GPU cards aren’t really differentiated by gaming performance. Gaming performance is going to be within a few percentage points of all devices, no matter what, because they’re ultimately governed by the GPU. A manufacturer can throw the world’s best PCB, VRM, and cooler together, and it’s still going to hit a Pascal wall of voltage and power budget. Further, chip quality dictates performance in greater ways than PCB or VRM will. We have duplicates of most of our cards, and they can perform 1-3% apart from one another, depending on which boosts higher out-of-box.
NVidia’s Titan Xp 2017 model video card was announced without any pre-briefing for us, marking it the second recent Titan X model card that took us by surprise on launch day. The Titan Xp, as it turns out, isn’t necessarily targeted at gaming – though it does still bear the GeForce GTX mark. NVidia’s Titan Xp followed the previous Titan X (that we called “Titan XP” to reduce confusion from the Titan X – Maxwell before that), and knocks the Titan X 2016 out of its $1200 price bracket.
The Titan Xp 2017 now firmly socketed into the $1200 category, we’ve got a gap between the GTX 1080 Ti at $700 MSRP ($750 common price) of $450-$500 to the TiXp. Even with that big of a gap, though, diminishing returns in gaming or consumer workloads are to be expected. Today, we’re benchmarking and reviewing the nVidia Titan Xp for gaming specifically, with additional thermal, power, and noise tests included. This card may be better deployed for neural net and deep learning applications, but that won’t stop enthusiasts from buying it simply to have “the best.” For them, we’d like to have some benchmarks online.
EVGA’s GTX 1080 Ti SC2 ($720) card uses the same ICX cooler that we reviewed back in February, where we intensely detailed how the new solution works (including information on the negative type thermistors and accuracy validation of those sensors). To get caught-up on ICX, we’d strongly recommend reading the first page of that review, and then maybe checking the thermal analysis for A/B testing versus ACX in an identical environment. As a fun add, we’re also A/B testing the faceplate – it’s got all those holes in it, so we thought we’d close them off and see if they actually help with cooling.
The fast version is basically this: EVGA, responding to concerns about ACX last year, decided to fully reinvent its flagship cooler to better monitor and cool power components in addition to the GPU component. The company did this by introducing NTC thermistors to its PCB, used for measuring GPU backside temperature (rather useless in a vacuum, but more of a validation thing when considering last year’s backplate testing), memory temperature, and power component temperature. There are thermistors placed adjacent to 5 MOSFETs, 3 memory modules, and the GPU backside. The thermistors are not embedded in the package, but placed close enough to get an accurate reading for thermals in each potential hotspot. We previously validated these thermistors versus our own thermocouples, finding that EVGA’s readings were accurate to reality.
Although this is absolutely a unique, innovative approach to GPU cooling – no one else does it, after all – we found its usefulness to primarily be relegated to noise output. After all, a dual-fan ACX cooler was already enough to keep the GPU cool (and FETs, with the help of some thermal pads), and ICX is still a dual-fan cooler. The ICX sensors primarily add a toy for enthusiasts to play with, as it won’t improve gaming performance in any meaningful way, though those enthusiasts could benefit from fine-tuning the fan curve to reduce VRM fan speeds. This would benefit in noise levels, as the VRM fan doesn’t need to spin all that fast (FETs can take ~125C heat before they start losing efficiency in any meaningful way), and so the GPU + VRM fans can spin asynchronously to help with the noise profile. Out of box, EVGA’s fan curve is a bit aggressive, we think – but we’ll talk about that later.
AMD’s Polaris refresh primarily features a BIOS overhaul, which assists in power management during idle or low-load workloads, but also ships with natively higher clocks and additional overvoltage headroom. Technically, an RX 400-series card could be flashed to its 500-series counterpart, though we haven’t begun investigation into that just yet. The reasoning, though, is because the change between the two series is so small; this is not meant to be an upgrade for existing 400-series users, but an option for buyers in the market for a completely new system.
We’ve already reviewed the RX 580 line by opening up with our MSI RX 580 Gaming X review, a $245 card that competes closely with the EVGA GTX 1060 SSC ($250) alternative from nVidia. Performance was on-point to provide back-and-forth trades depending on games, with power draw boosted over the 400 series when under load, or lowered when idle. This review of the Gigabyte RX 570 4GB Aorus card benchmarks performance versus the RX 470, 480, 580, and GTX 1050 Ti and 1060 cards. We're looking at power consumption, thermals, and FPS.
There’s no new architecture to speak of here. Our RX 480 initial review from last year covers all relevant aspects of architecture for the RX 500 series; if you’re behind on Polaris (or it’s been a while) and need a refresher on what’s happening at a silicon level, check our initial RX 480 review.
AMD’s got a new strategy: Don’t give anyone time to blink between product launches. The company’s been firing off round after round of products for the past month, starting with Ryzen 7, then Ryzen 5, and now Polaris Refresh. The product cannon will eventually be reloaded with Vega, but that’s not for today.
The RX 500 series officially arrives to market today, primarily carried in on the backs of the RX 580 and RX 570 Polaris 10 GPUs. From an architectural perspective, there’s nothing new – if you know Polaris and the RX 400 series, you know the RX 500 series. This is not an exciting, bombastic launch that requires delving into some unexplored arch; in fact, our original RX 480 review heavily detailed Polaris architecture, and that’s all relevant information to today’s RX 580 launch. If you’re not up to speed on Polaris, our review from last year is a good place to start (though the numbers are now out of date, the information is still accurate).
Both the RX 580 and RX 570 will be available as of this article’s publication. The RX 580 we’re reviewing should be listed here once retailer embargo lifts, with our RX 570 model posting here. Our RX 570 review goes live tomorrow. We’re spacing them out to allow for better per-card depth, having just come off of a series of 1080 Ti reviews (Xtreme, Gaming X).
Our Gigabyte GTX 1080 Ti Aorus Xtreme ($750) review brings us to look at one of the largest video cards in the 1080 Ti family, matching it well versus the MSI 1080 Ti Gaming X. Our tests today will look at the Aorus Xtreme GPU in thermals (most heavily), noise levels, gaming performance, and overclocking, with particular interest in the efficacy of Gigabyte’s copper insert in the backplate. The Gigabyte Aorus Xtreme is a heavyweight in all departments – size being one of them – and is priced at $750, matching the MSI Gaming X directly. A major point of differentiation is the bigger focus on RGB LEDs with Gigabyte’s model, though the three-fan design is also interesting from a thermal and noise perspective. We’ll look at that more on page 3.
We’ve already posted a tear-down of this card (and friend of the site ‘Buildzoid’ has posted his PCB analysis), but we’ll recap some of the PCB and cooler basics on this first page. The card uses a 3-fan cooler (with smaller fans than the Gaming X-type cards, but more of them) and large aluminum heatsink, ultimately taking up nearly 3 PCI-e slots. It’s the same GPU and memory underneath as all other GTX 1080 Ti cards, with differences primarily in the cooling and power management departments. Clock, of course, does have some pre-OC applied to help boost over the reference model. Gigabyte is shipping the Xtreme variant of the 1080 Ti at 1632/1746MHz (OC mode) or 1607/1721 (gaming mode), toggleable through software if not manually overclocking.
We’re reviewing the new MSI GTX 1080 Ti Gaming X card today, priced at $750 and positioned as one of the highest-performing gaming cards on the market. These tests will extensively look at thermals, given that that’s the primary differentiator between same-GPU video cards, and then look at gaming performance (in FPS) versus the Reference card and our Hybrid mod FE card. Part of our thermal testing will include performance analysis with and without a backplate. Noise levels are going to be the same as the last Twin Frozr card we tested, which can be found here.
This generation of GTX 1080 Ti cards has gone big. MSI’s Gaming X is already large, but the Gigabyte unit that we’re reviewing next is similarly big in the multi-slot department. The Gaming X uses MSI’s known twin-frozr cooler, with modifications to the underlying aluminum heatsink to increase surface area and fin density. Noise output is therefore identical to the noise output of previous Twin Frozr coolers we reviewed for the 10-series, including the GTX 1080 non-Ti Gaming X.
MSI ships the 1080 Ti Gaming X at three different frequencies, configurable through software: OC mode runs at 1683MHz boost and 1569MHz base, Gaming mode runs at 1657MHz boost and 1544MHz base, and silent mode runs at 1582 and 1480MHz.
