​NVIDIA’s GeForce GTX 1080 is a PC gamer’s dream

It’s never been a better time to be a PC gamer. Hardware is getting both cheaper and more powerful, most big-budget console games are making it to PCs (where they also look better), and the rise of virtual reality offers a tempting upgrade target. NVIDIA, one of the pioneering graphics card designers, is taking full advantage of this revitalized PC gaming market with the GeForce GTX 1080 , its latest powerhouse GPU. It’s the first consumer card built on the company’s Pascal architecture, and most intriguingly, NVIDIA claims the $599 video card ($699 for the special “Founder’s Edition”) is faster than the Titan X , which goes for upwards of $1, 000. After testing it out over the past week, I can say the 1080 is clearly something special. Hardware I had the privilege of testing the Founder’s Edition of the card, which is something unique for NVIDIA. Previously, the company released fairly plain reference editions of its cards, which would inevitably be one-upped by partners with more elaborate cooling designs. But NVIDIA is positioning the GTX 1080 Founder’s Edition as a premium offering. The company claims the materials used to build the card, including the aluminum vapor chamber cooler (a step up from plain old air cooling) and more efficient power components, justify its $100 premium. But that’s a bit hard to stomach when its reference cards had similar cooler designs in the past. NVIDIA went for a bit more flair this time around. The sharp angles around the 1080’s cooler feel more reminiscent of a Ferrari than the company’s past designed. That’s a fitting way to represent just how fast it is: It’s capable of pumping out nine teraflops of computing power. The 1080 runs at 1, 607MHz (up to 1, 733MHz in boost mode) and packs in 8GB of Micron’s new DDR5X RAM. In comparison, last year’s 980 Ti card clocked in at 1, 000MHz with 6GB of standard DDR5 memory. Unlike CPUs, video cards haven’t seen massive megahertz bumps over the past few years, so the 1080’s numbers are seriously impressive. You can chalk up much of the GTX 1080’s upgrades to NVIDIA’s new Pascal architecture. It first appeared on the P100 card for data crunchers, but this is the first time we’ve seen what it looks like in consumer hardware. The big benefit with Pascal is its new 16nm FinFET architecture (a type of 3D transistor technology). It allows NVIDIA to reach higher clock speeds, as well as make the card much more power efficient. In terms of connectivity, the 1080 Founder’s Edition features 3 DisplayPort connections, one HDMI port and a single DVI socket. It would have been nice to see another HDMI port, but I’m sure there are plenty of professionals out there who are still running fancy monitors over DVI. Setup Getting the GTX 1080 up and running isn’t any different than you typical video card. It’s a big piece of kit, so you’ll want to make sure there’s enough room in your case for it to fit, but otherwise it snaps right into a PCI-X slot. Unlike the Radeon R9 Fury X, which required me to move some case fans around to make room for its water cooler radiator, the GTX 1080 was a cinch to install. After grabbing some fresh drivers from NVIDIA (and making sure any traces of old drivers were gone for good), I was off to the benchmarking races. Performance NVIDIA wasn’t lying: The GTX 1080 is a beast. I only had the R9 Fury X to compare it to on my gaming rig (which consists of a 4GHz Core i7-4790K CPU, 16GB of 2400Mz DDR3 RAM and a 512GB Crucial MX100 SSD on a ASUS Z97-A motherboard), but that’s a powerhouse GPU that easily keeps pace with the GTX 980 and Titan X. And for every major benchmark, the 1080 was significantly faster. 3DMark 3DMark 11 NVIDIA GeForce GTX 1080 Standard 15, 859/ Extreme 9, 316/ Ultra 5, 021 X9, 423 AMD R9 Fury X Standard 13, 337/ Extreme 7, 249/ Ultra 3, 899 X, 6457 In 3DMark online comparisons with similar systems, the 1080 was typically ranked better than 92 to 95 percent of results. It was only bested by scores from machines running multiple 980 and 980 Ti cards in SLI mode (which would also cost a lot more than the 1080 to put together). Witcher 3 Hitman Fallout 4 NVIDIA GeForce GTX 1080 43 48 54 AMD R9 Fury X 35 38 42 Average FPS performance in 4K with all graphics set to maximum. Still, benchmarks are one thing: I was more interested in how the GTX 1080 performs in actual games. And once again, it didn’t disappoint. Compared to the R9 Fury X, it reached around 43 frames per second in the Witcher 3 while running in 4K with all of the settings set to Ultra. That made the game much more playable in such a high resolution — the Fury X averaged around 35 fps, and it would sometimes dip below 30, which makes things unbearably jerky. For Hitman , the 1080 reached a smooth 48 fps on average, whereas the Fury X hovered around 38. I was particularly impressed with the card’s performance in Fallout 4 (after turning off that game’s frame limiter). It was playable on the Fury X, reaching around 42 fps, but on the GTX 1080 it more often hovered between 50 and 55 fps in most environments. Sometimes it would shoot upwards of 60fps indoors, and in wide open areas it would dip to 40 fps. That wouldn’t make for the smoothest experience, but it’s certainly a lot more playable in 4K. Thanks to the elaborate heatsink design, the GTX 1080 Founder’s Edition was also cooler than I expected. It idled at a mere 33c, and under full load it reached between 65c and 70c. I also had no trouble overclocking the GPU by 250MHz (reaching around 1.95 GHz under load), and the memory by 200MHz, without any significant temperature changes. NVIDIA reps managed to push the card past 2.1GHz during a stage demo without any additional cooling. If you’re into overclocking, this card was basically made for you. Last year I wasn’t sold on the viability of 4K gaming — if a $600 card like the R9 Fury X couldn’t always handle it, why even bother? — but the GTX 1080 actually makes it viable with a single card. But while it’s nice to see significant progress in high-res gaming, I still prefer bumping down to a lower resolution like 2, 560 x 1, 440 to ensure a silky 60fps experience. Most people wouldn’t notice the marginal difference in rendering resolution, but they’d certainly pick out when frames start to stutter in 4K. Even if you’re not chasing 4K, a powerful card like the 1080 could be used to “supersample” games, which involves rendering them at a higher resolution than what’s being shown on the screen to remove unsightly jagged lines. It’s a technique that’s fallen out of fashion in the PC gaming world, but now that cards have computing power to spare, it could be a smart way to make games look even better. With Hitman, I was able to get around 60 fps when running it at 2, 560 x 1, 440 with a 1.2X supersample. I couldn’t see a huge difference without enabling the feature, but this is the sort of thing that some PC gamers might eat up. When it comes to VR, the GTX 1080 doesn’t feel significantly better than the R9 Fury X. That’s partially because the Oculus Rift and HTC Vive run at a relatively low 1, 200-by-1, 080-pixel resolution for each eye display, which is significantly less sharp than the 1080p HD screens we’ve grown used to. You need to reach at least 90 fps in VR to make games look smooth, but that’s not a tough target for the 1080 to reach at such a low resolution. NVIDIA has also included some new technology, dubbed Simultaneous Multi-Projection, which makes the 1080 more efficient at displaying VR scenes than other cards. For example, it only needs to render a scene once to show it in VR, whereas other video cards have to do that work twice (once for each eye). The card is also much smarter about processing the pixels you actually need to see in a scene. These new innovations won’t make a big impact on existing VR games, which don’t need to be displayed in high resolutions, but they could be a big deal with next-generation headsets. The competition As great as the GTX 1080 is, most gamers will likely opt for its cheaper sibling, the $379 GTX 1070 ($449 for the Founders Edition). It’s only slightly slower — pumping out 6.5 teraflops instead of the 1080’s nine terfalops — but NVIDIA says it’s also “roughly” the same performance as the $1, 000 Titan X. That’s an insane cost/performance ratio, and it also leaves room for snapping up another (inevitably cheaper) 1070 in a year or so to bump your speeds up. As is usually the case, there will also be plenty of competing GTX 1080 designs to choose from in the next few months. Those cards will likely come in closer to the $599 retail price NVIDIA is advertising, rather than the $699 premium for the Founders Edition. Normally, I’d also urge you to look at previous-generation hardware as new gear comes in. But the 1070 and 1080 are such huge architectural leaps that it doesn’t make sense for most people to consider a 970 or 980. If you’re really trying to save money, a 970 for around $200 could be a decent deal in the future (they’re still going for around $300). But you’d also regret that choice if you want to dabble in VR within the next year. AMD has also shown off its next-generation graphics technology, Polaris , which promises to be just as power efficient as NVIDIA’s Pascal. We still don’t know what Polaris consumer cards will look like yet, so it might pay off to wait a few months before you decide on a new GPU. Wrap-up If you have the cash, and need the most powerful video card on the market, you can’t go wrong with the GTX 1080. It’s built precisely for the things gamers are focused on today: 4K and VR. It’s not just an incremental upgrade for NVIDIA: It’s a dramatic leap forward.

Hyperloop One is testing its propulsion system in the Nevada desert today

Hyperloop One Here’s a look at the sled Hyperloop One is testing in North Las Vegas today. 4 more images in gallery In North Las Vegas today, a startup called Hyperloop One propelled a 10-foot-long sled down a track, accelerating it to 116 mph before it hit a patch of sand on the tracks. The test took about four seconds, USA Today reported . The test of Hyperloop One’s propulsion system is just one step of many on the path to achieve a dream put forth by Tesla and SpaceX CEO Elon Musk, who first drew up a plan to transport people at 760mph in low-pressure tubes in 2013. Musk decided not to pursue this business venture, which he called Hyperloop, but his whitepaper spawned two rival Hyperloop companies and an international student engineer competition . Hyperloop One, formerly known Hyperloop Technologies, announced its name change on Tuesday, hoping to differentiate itself from Hyperloop Transportation Technologies (HTT), which has also made considerable headway in research and development of such a transportation system. HTT announced on Monday that it had exclusively licensed passive magnetic levitation technology that would serve to keep Hyperloop pods off the track, minimizing friction as they speed through a tube.

NVIDIA’s GTX 1080 GPU is twice as fast the Titan X

NVIDIA gave us a taste of its new Pascal architecture with the P100 graphics card last month, which is aimed at servers for heavy duty computing. Now, it’s ready to show off how that technology will be adapted for consumers with its new GeForce GTX 1080 GPU. As you’d expect, it’s fast: NVIDIA CEO Jen-Hsun Huang revealed that it’s better than its current performance king, the Titan X. It’s also faster than two GTX 980 cards running together using SLI technology. Like the P100, the 1080 is built with a new 16nm FinFET (a type of 3D transistor) manufacturing process, which makes it more power efficient, on top of just being faster. The GTX 1080 is the “largest GPU endeavor, largest chip endeavor, largest processor endeavor, in the history of humanity, ” said NVIDIA CEO Jen-Hsun Huang. He added that the R&D budget for the new card was “several billion dollars” over the span of more than two years. “I’m pretty sure you can go to Mars [for that], ” he said. NVIDIA is basically positioning the GTX 1080 as the gamer’s dream card. Prior to its unveiling, Huang showed off several new titles like The Division and Rise of the Tomb Raider running at max settings in a high resolution over 60 frames per second. He later revealed that all of the games were running on the new card, to the delight of the entire crowd. But of course, NVIDIA won’t be alone with new hardware this year. AMD is expected to debut new cards with its Polaris technology this summer, which will focus on power efficiency as well. It sounds like Polaris is better suited for gaming laptops at the moment, but it could also be a way for AMD to deliver some powerful cards that you can actually afford (think under $300).

Acer unveils a liquid-cooled laptop, simplified UI tablet for “super-seniors”

(credit: Valentina Palladino) NEW YORK—Acer has been busy, and the company showed off some of its latest work at an event in New York City today. Acer announced a slew of new laptops and PCs, many of which build upon some of its other recently released products. The Switch Alpha 12 laptop is the juiced-up version of its Aspire Switch 12 S that was announced back at CES. Instead of the Switch 12 S’s Core M processor, the Alpha 12 supports sixth-generation Core i3U, i5, and i7 processors. But Acer is pushing this device as an efficient and cool laptop above anything else. Engineers built the Switch Alpha 12 with a liquid cooling system and a fanless design. The heat created from the device powers the cooling system, keeping temperatures down. And since it lacks a fan all together, operating sounds are kept quiet. Read 6 remaining paragraphs | Comments

The Ars guide to building a Linux router from scratch

The Homebrew Special—looking a bit blurry, because I wanted to take a low-light shot to try to capture the disco glow. 2 more images in gallery After finally reaching the tipping point with off-the-shelf solutions that can’t match increasing speeds available, we recently took the plunge. Building a homebrew router  turned out to be a better proposition than we could’ve ever imagined. With nearly any speed metric we analyzed, our little DIY kit outpaced routers whether they were of the $90- or $250-variety. Naturally, many readers asked the obvious follow-up—”How exactly can we  put that together?” Today it’s time to finally pull back the curtain and offer that walkthrough. By taking a closer look at the actual build itself (hardware and software), the testing processes we used, and why we used them, hopefully any Ars readers of average technical abilities will be able to put together their own DIY speed machine. And the good news? Everything is as open source as it gets—the equipment, the processes, and the setup. If you want the DIY router we used, you can absolutely have it. This will be the guide to lead you, step-by-step. What is a router, anyway? At its most basic, a router is just a device that accepts packets on one interface and forwards them on to another interface that gets those packets closer to their eventual destination. That’s not what most of us are really thinking when we think of “a router” in the sense of something we’ll plug into our home or office to get to the Internet, though. What do we need to have before any homebrew device looks like a router? Read 66 remaining paragraphs | Comments

This tattoo-like display is made possible by a new ultra-thin protective ‘E-skin’

 It sounds like something out of Star Trek: a patch thinner than a band-aid that you slap on your arm and, within moments, it lights up with heart rate, blood sugar, and so on — then peels off a few days later. That’s the goal of work by researchers at the University of Tokyo. Read More

Carbon fiber strings protect buildings against earthquakes

The problem with earthquake -proofing a building is that it usually involves grafting on a lot of support — not really an option with historic buildings or other particularly delicate structures. Komatsu Seiren Fabric Laboratory might have a better way, however. Its carbon fiber-based CABKOMA Strand Rods can protect a building against quakes by tying the roof to the ground, making sure that the whole building moves together — and thus stays together — during a tremor. The fibers are both very strong and very light (you can easily carry a 520-foot strand by yourself), so it’s more like draping spiderwebs over a building than anchors. As you might have gathered just by looking at the photo above, the technology has its limits. It won’t work for tall buildings, or those in dense urban areas where there’s simply no room. This is more for mid-size structures that have plenty of free space. All the same, it might be the key to saving lives in areas where conventional bolts and braces just won’t work.

Amazon CEO says a brand-new flagship Kindle is coming next week

If you’re thinking about buying a Kindle Voyage, you probably should hold off. Amazon CEO Jeff Bezos just tweeted this morning that the company is ready to release an “all-new, top of the line” Kindle next week. Presumably, that’ll be a replacement for the aging but still powerful Kindle Voyage , which was released back in the fall of 2014. It’s still an excellent e-reader (albeit an expensive one at $200), but the mid-range Kindle Paperwhite has since adopted its high-resolution screen at a much lower price. Heads up readers – all-new, top of the line Kindle almost ready. 8th generation. Details next week. — Jeff Bezos (@JeffBezos) April 4, 2016 The Voyage is still slightly smaller and lighter than the Paperwhite; it also features a screen with adaptive lighting technology and has pressure-sensitive page turn buttons. But for most readers, the cheaper Paperwhite is the better buy. We’ll see what Amazon has to differentiate its new e-reader from the Voyage next week, but as for now Bezos isn’t dropping any other details. It’s also worth noting that this is a pretty strange way to drop some news — most new device launches are obviously shrouded in secrecy. Bezos’ transparency around this implies that it’s not that big of a deal, despite his “all-new” proclamation. And e-readers aren’t exactly hotly anticipated gadgets at this point; Amazon got the formula right with the Kindle and continues to dominate the market with it. So there’s not a whole lot for Bezos to lose by giving the masses a little tease of what’s coming next. Source: Jeff Bezos (Twitter)
