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.
The GTX 1080 Ti posed a fun opportunity to roll-out our new GPU test bench, something we’ve been working on since end of last year. The updated bench puts a new emphasis on thermal testing, borrowing methodology from our EVGA ICX review, and now analyzes cooler efficacy as it pertains to non-GPU components (read: MOSFETs, backplate, VRAM).
In addition to this, of course, we’ll be conducting a new suite of game FPS benchmarks, running synthetics, and preparing for overclocking and noise. The last two items won’t make it into today’s content given PAX being hours away, but they’re coming. We will be starting our Hybrid series today, for fans of that. Check here shortly for that.
If it’s not obvious, we’re reviewing nVidia’s GTX 1080 Ti Founders Edition card today, follow-up to the GTX 1080 and gen-old 980 Ti. Included on the benches are the 1080, 1080 Ti, 1070, 980 Ti, and in some, an RX 480 to represent the $250 market. We’re still adding cards to this brand new bench, but that’s where we’re starting. Please exercise patience as we continue to iterate on this platform and build a new dataset. Last year’s was built up over an entire launch cycle.
NVidia just opened the floodgate on its GTX 1080 Ti video card, the Pascal-based mid-step between the GTX 1080 and GTX Titan X. The 1080 Ti opens up SMs over the GTX 1080, now totaling 28 SMs over the 1080’s 20 SMs, resulting in 3584 total FP32 CUDA cores on the GTX 1080 Ti. Simultaneous multiprocessor architecture remains the same – Pascal hasn’t changed, here – leaving us with primary changes in the memory subsystem.
The GTX 1080 Ti will host 11GB of GDDR5X memory – not HBM2 – with a speed of 11Gbps. This is boosted over the GTX 1080’s 10Gbps GDDR5X memory speeds, resultant of work done by memory supplier Micron to clean the signal. The heavy transition cluttering of early G5X iterations have been reduced, allowing a cleaner signal in the GDDR5X cells without data corruption concerns. We’ll have some news below on how this also relates to existing Pascal cards.
NVidia has added to our pile of pre-CES hardware news with the announcement of GTX 1050 and 1050 Ti-equipped laptops. 30+ models from various OEMs will be arriving in Q1 2017, including several using Intel’s new Kaby Lake CPUs this week at CES. Confirmed manufacturers include Acer, Alienware/Dell, ASUS, HP, Lenovo, and MSI.
As mentioned in our laptop 1060/1070/1080 benchmark, improvements to power management mean that nVidia’s 10-series notebook GPUs are the real deal, rather than the neutered “-M” versions that laptops have gotten in the past. The specs listed for the notebook GPUs confirm this, with the only major difference being higher core clock speeds in the notebook 1050 and 1050 Ti. This doesn’t indicate a change in the physical hardware, it mostly seems that nVidia has increased the clock-rate given the high thermal headroom (room to increase heat) as a result of the efficient 1050/Ti GPUs. Like other 10-series laptops, OEMs will probably be allowed an additional +/-10% for overclocking their GPUs.
The Nintendo “Switch” was announced this morning, the next-generation half-portable, half-docked console. To reduce confusion, the Switch was previously referred to as the Nintendo “NX.” It is the same device.
Nintendo's new Switch is built in partnership with nVidia and leverages the Pascal architecture found in current-generation GTX 10-series GPUs. At least, based on this text from nVidia's blog: "[...] NVIDIA GPU based on the same architecture as the world’s top-performing GeForce gaming graphics cards." Tegra SOCs include ARM processors alongside the nVidia graphics solution, and also host all of the I/O lanes and memory interfaces. This is a complete system, as indicated by “system on chip.” We've asked nVidia for details on which ARM devices are used and which memory will be supported, but were told that the company is not revealing further details on Nintendo's product. We are awaiting comment from Nintendo for more information.
We do know that the Tegra SOC is accelerating gameplay with hardware-acceleration for video playback, and that nVidia and Nintendo have deployed “custom software for audio effects and rendering.” We can confidently speculate that the Switch is not functioning as the previous Shield devices have (read: not streaming to handheld from a dock), mostly because the Switch is large enough to contain all necessary render hardware within its handheld state. The Switch is also shown in the advert to be playable on planes, which most certainly do not have fast enough internet to support up/down game streaming. This is processing and rendering locally.
Buildzoid returns this week to analyze the PCB and VRM of Gigabyte's GTX 1080 Xtreme Water Force GPU, providing new insight to the card's overclocking capabilities. We showed a maximum overclock of 2151.5MHz on the Gigabyte GTX 1080 Xtreme Water Force, but the card's stable OC landed it at just 2100.5MHz. Compared to the FTW Hybrid (2151.5MHz overclock sustained) and MSI Sea Hawk 1080 (2050MHz overclock sustained), the Gigabyte Xtreme Water Force's overkill VRM & cooling land it between the two competitors.
But we talk about all of that in the review; today, we're focused on the PCB and VRM exclusively.
The card uses a 12-phase core voltage VRM with a 2-phase memory voltage VRM, relying on Fairchild Semiconductor and uPI Micro for most the other components. Learn more here:
The GTX 980's placement in notebooks heralded the now-present era of desktop GPUs in laptops, but was still sort of a trial of the tech. NVidia and AMD have both introduced their Pascal and Polaris architectures in full, uncut versions to notebooks this generation, with performance generally within about 10% of an equivalent desktop build. Despite the desktop-level power, battery life should also be improved resultant of an overall reduction in power consumption by the GPU and the CPU alike. And almost every other component, for that matter – like DDR4, which requires lower voltage and draws less power than DDR3.
Today, we're looking at the MSI GE62VR 6RF Apache Pro laptop with GTX 1060 & i7-6700HQ, priced at $1600. The benchmarks follow our previous notebook 1070 vs. 1080 tests, but with proper depth and hands-on. Note also that we already wrote about the GE62VR's bloatware problem.
In this review of the MSI GE62VR 6RF Apache Pro ($1600), we'll be testing FPS on the GTX 1060, temperatures, noise levels, and build quality.
MSI and system integrator CyberPower are selling the new GT83VR Titan SLI notebook, which sells with K-SKU Intel CPUs and dual GTX 1070 or GTX 1080 GPUs. The move away from M-suffixed cards means that these GPUs are effectively identical to their desktop counterparts, with the exception of the GTX 1070's core increase and clock reduction.
That difference, just to quickly clear it away, results in 2048 CUDA cores on the notebook 1070 (vs. 1920 on the desktop) and a baseline clock-rate of 1645MHz on the notebook (1683MHz on the desktop). Despite talk about the 1060, 1070, and 1080 model notebooks, we haven't yet gotten into the SLI models for this generation.
The GTX 1060 3GB ($200) card's existence is curious. The card was initially rumored to exist prior to the 1060 6GB's official announcement, and was quickly debunked as mythological. Exactly one month later, nVidia did announce a 3GB GTX 1060 variant – but with one fewer SM, reducing the core count by 10%. That drops the GTX 1060 from 1280 CUDA cores to 1152 CUDA cores (128 cores per SM), alongside 8 fewer TMUs. Of course, there's also the memory reduction from 6GB to 3GB.
The rest of the specs, however, remain the same. The clock-rate has the same baseline 1708MHz boost target, the memory speed remains 8Gbps effective, and the GPU itself is still a declared GP106-400 chip (rev A1, for our sample). That makes this most the way toward a GTX 1060 as initially announced, aside from the disabled SM and halved VRAM. Still, nVidia's marketing language declared a 5% performance loss from the 6GB card (despite a 10% reduction in cores), and so we decided to put those claims to the test.
In this benchmark, we'll be reviewing the EVGA GTX 1060 3GB vs. GTX 1060 6GB performance in a clock-for-clock test, with 100% of the focus on FPS. The goal here is not to look at the potential for marginally changed thermals (which hinges more on AIB cooler than anything) or potentially decreased power, but to instead look strictly at the impact on FPS from the GTX 1060 3GB card's changes. In this regard, we're very much answering the “is a 1060 6GB worth it?” question, just in a less SEF fashion. The GTX 1060s will be clocked the same, within normal GPU Boost 3.0 variance, and will only be differentiated in the SM & VRAM count.
For those curious, we previously took this magnifying glass to the RX 480 8GB & 4GB cards, where we pitted the two against one another in a versus. In that scenario, AMD also reduced the memory clock of the 4GB models, but the rest remained the same.
The review is forthcoming – within a few hours – but we decided to tear-down EVGA's GTX 1080 FTW Hybrid ahead of the final review. The card is more advanced in its PCB and cooling solution than what we saw in the Corsair Hydro GFX / MSI Sea Hawk X tear-down, primarily because EVGA is deploying a Gigabyte-like coldplate that conducts thermals from the VRAM and to the CLC coldplate. It's an interesting fusion of cooling solutions, and one which makes GPU temperatures look higher than seems reasonable on the surface – prompting the tear-down – but is actually cooling multiple devices.
Anyway, here's a video of the tear-down process – photos to follow.
