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 If you’re not up to speed on Polaris, our review from last year is a good place to start (though the numbers are now out of date, the information is still accurate).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.
On the heels of the media world referring to the Titan X (Pascal) as Titan XP – mostly to reduce confusion versus the previous Titan X – nVidia today announced its actual Titan Xp (lowercase ‘p,’ very important) successor to the Titan XP. Lest Titan X, Titan X, and Titan X be too confusing, we’ll be referring to these as Titan XM [Maxwell], Titan X (Pascal), and Titan Xp. We really should apologize to Nintendo for making fun of their naming scheme, as nVidia seems to now be in competition; next, we’ll have the New Titan Xp (early 2017).
Someone at nVidia is giddy over taking the world’s Titan XP name and changing it, we’re sure.
Benchmarking Mass Effect: Andromeda immediately revealed a few considerations for our finalized testing. Frametimes, for instance, were markedly lower on the first test pass. The game also prides itself in casting players into a variety of environs, including ship interiors, planet surfaces of varying geometric complexity (generally simpler), and space stations with high poly density. Given all these gameplay options, we prefaced our final benchmarking with an extensive study period to research the game’s performance in various areas, then determine which area best represented the whole experience.
Our Mass Effect: Andromeda benchmark starts with definitions of settings (like framebuffer format), then goes through research, then the final benchmarks at 4K, 1440p, and 1080p.
Buildzoid's latest contribution to our site is his analysis of the GTX 1080 Ti Founders Edition PCB and VRM, including some additional thoughts on shunt modding the card for additional OC headroom. We already reviewed the GTX 1080 Ti here, modded it for increased performance with liquid cooling, and we're now back to see if nVidia's reference board is any good.
This time, it turns out, the board is seriously overbuilt and a good option for waterblock users (or users who'd like to do a Hybrid mod like we did, considering the thermal limitations of the FE cooler). NVidia's main shortcoming with the 1080 Ti FE is its FE cooler, which limits clock boosting headroom even when operating stock. Here's Buildzoid's analysis:
We’ve fixed the GTX 1080 Ti Founders Edition ($700) card. As stated in the initial review, the card performed reasonably close to nVidia’s “35% > 1080” metric when at 4K resolutions, but generally fell closer to 25-30% faster at 4K. That’s really not bad – but it could be better, even with the reference PCB. It’s the cooler that’s holding nVidia’s card back, as seems to be the trend given GPU Boost 3.0 + FE cooler designs. A reference card is more versatile for deployment to the SIs and wider channel, but for our audience, we can rebuild it. We have the technology.
“Technology,” here, mostly meaning “propylene glycol.”
Our review of the nVidia GTX 1080 Ti Founders Edition card went live earlier this morning, largely receiving praise for jaunts in performance while remaining the subject of criticism from a thermal standpoint. As we've often done, we decided to fix it. Modding the GTX 1080 Ti will bring our card up to higher native clock-rates by eliminating the thermal limitation, and can be done with the help of an EVGA Hybrid kit and a reference design. We've got both, and started the project prior to departing for PAX East this weekend.
This is part 1, the tear-down. As the content is being published, we are already on-site in Boston for the event, so part 2 will not see light until early next week. We hope to finalize our data on VRM/FET and GPU temperatures (related to clock speed) immediately following PAX East. These projects are always exciting, as they help us learn more about how a GPU behaves. We did similar projects for the RX 480 and GTX 1080 at launch last year.
Here's part 1:
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.
Ryzen, Vega, and 1080 Ti news has flanked another major launch in the hardware world, though this one is outside of the PC space: Nintendo’s Switch, formerly known as the “NX.”
We purchased a Nintendo Switch ($300) specifically for teardown, hoping to document the process for any future users wishing to exercise their right to repair. Thermal compound replacement, as we learned from this teardown, is actually not too difficult. We work with small form factor boxes all the time, normally laptops, and replace compound every few years on our personal machines. There have certainly been consoles in the past that benefited from eventual thermal compound replacements, so perhaps this teardown will help in the event someone’s Switch encounters a similar scenario.
Not long ago, we opened discussion about AMD’s new OCAT tool, a software overhaul of PresentMon that we had beta tested for AMD pre-launch. In the interim, and for the past five or so months, we’ve also been silently testing a new version of FCAT that adds functionality for VR benchmarking. This benchmark suite tackles the significant challenges of intercepting VR performance data, further offering new means of analyzing warp misses and drop frames. Finally, after several months of testing, we can talk about the new FCAT VR hardware and software capture utilities.
This tool functions in two pieces: Software and hardware capture.
