![]() Typically when we move from one generation to the next, such as the GTX 780 to the GTX 980 we’ll see a 20 to 30 percent difference in performance, but not this time around. When it comes to the GTX 980, which the 1080 is actually replacing, there really is no comparison at all. Sapphire Radeon RX 590 Nitro josh noremOverall though, the GTX 1080 offers quite a boost from the 980 Ti, which is remarkable as it uses a “Big Maxwell” chip with a die size of 601mm (squared) compared to the 1080’s comparatively tiny 314mm (squared). (Thank you to IGN sister-site Computer Shopper for supplying the GTX 1080 benchmarks). The card was tested at both 3840x2160, 2560x1440, and 1920x1080 resolution, and we’ve compiled the results into the following charts. The BenchmarksTo test the GTX 1080 we pulled some data from our sister site Computer Shopper, which tested it on a system featuring the following specs: Also, it goes without saying that this GPU far exceeds the minimum qualifications for VR, and is one of the best GPUs to buy if you’re planning on donning a headset in the near future. The cliff notes summary of them is that it offers improved performance in multi-display applications including VR via a feature called Simultaneous Multi-Projection (in games that support it), the ability to take high-res in-game screenshots with a free camera you control (also has to be supported by the developer), and a new refresh rate syncing option for high frame rate gamers (esports mostly). In addition to offering more power and efficiency, Nvidia has also baked some new features into its Pascal chips as well. “Further proof of its efficiency is the fact that despite being much more powerful than the previous generation cards, it needs just a lone eight-pin connector to power it, and its power consumption measured in TDP has only gone up by 15w overall. Ironically the GTX 980 Ti, which was more CUDA cores, texture units, and ROPS should also be significantly less powerful than the 1080 a perfect demonstration of the efficiency of Nvidia’s new Pascal architecture. It has 25 percent more CUDA cores, double the memory from 4GB to 8GB (the memory is faster as well), and two billion more transistors. The SpecsCompared to the card it’s theoretically replacing, the GTX 980, the GTX 1080 has a bit more of everything. It also has a slight advantage in that it’s a premium blower design that exhausts hot air out of the chassis, and most of the partner card designs typically are just multi-fan that can’t exhaust heat at all, so the blower could be an advantage in a small form factor build. Nvidia claims it’s a masterpiece of engineering, and thus will cost $100 more than cards from its partners (MSI, Gigabyte, Asus, Zotac, et al.) It’s an odd decision on Nvidia’s part as the cards from its partners typically have more elaborate cooling solutions and can therefore possibly be overclocked higher, but the company claims it needs to offer its version at a premium in order to turn a profit and not upset its partners by competing directly with them on price. The company itself created what used to be called a reference design but is now labeled the Founder’s Edition. The GTX 1080 launched in two versions a first for Nvidia. For what it’s worth, AMD is making the same leap this time around with its new Polaris GPUs, except it went down to 14nm FinFET via a different fabrication company than Nvidia uses, setting the stage for a bloody technology showdown. This lets Nvidia practically double performance (in this instance) without changing the size of its die, all while using less power too. This process transition is both massive and unprecedented, and will afford a huge boost in performance and efficiency as the use of smaller transistors allows more to be packed into the same size space. This massive shrink in transistor size represents a two-generation leap since instead of going from 28nm to 20nm two years ago Nvidia (and AMD) skipped it and waited for 16nm to come online. The process used to make the chips shrunk quite a bit as well, going from 28nm in the previous generation for Kepler (GTX 680/780 family) and Maxwell (GTX 980 family) all the way down to 16nm for Pascal. Pascal PowerThe GTX 1080 is the first GPU created with the company’s new Pascal architecture, which it built over the past few years using a new manufacturing process that employs vertically stacked FinFET transistors instead of ones that are laid out side-by-side, also known as planar transistors. Brian Barnett + 1 moreThere will be two cards firing out of the gate - the GTX 1080 and the slightly detuned GTX 1070 - but first we’re going to examine “the new king” of GPUs to see if it’s worthy of that title. ![]()
