Add it all up and the new graphics card blows its predecessor out of the water in both gaming performance and compute tasks, leaping from 4,981 GFLOPS in the GTX 980 all the way to 8,873 GFLOPS in the GTX 1080.ĭiving even deeper, each Pascal Streaming Multiprocessor (SM) features 128 CUDA cores, 256KB of register file capability, a 96KB shared memory unit, 48KB of L1 cache, and eight texture units.
We managed to crank it to over 2GHz on air without breaking a sweat or tinkering with the card’s voltage. While the “GP104” Pascal GPU’s 314mm2 die size is considerably smaller than 398mm2 die in the older GTX 980, it still manages to squeeze in 2 billion more transistors overall, as well as 25 percent more CUDA cores-2560 in the GTX 1080, versus 2048 in the GTX 980.Ī block diagram of the Pascal GPU’s Streaming Multiprocessor design.Īnd pick up your jaw! The GTX 1080 indeed rocks utterly ridonkulous 1,607MHz base clock and 1,733MHz (!!!!) boost clock speeds-and that’s just the stock speeds. Here, some of the benefits to switching to 16nm jump out immediately. The GTX 960 was compared against the GTX 660- not the GTX 760-in Nvidia’s official materials, for example.) Usually, GPU makers compare new graphics cards against GPUs two generations back in review materials. (Side note: The mere fact that the company’s comparing the GTX 1080 directly against the GTX 980 is noteworthy. Let’s kick things off with an Nvidia-supplied spec sheet comparison of the GTX 1080 vs. If that’s not your thing, jump to page two for discussion on the GTX 1080’s big new technical wonders and page three for its new consumer-facing features. Note: Because this is a major GPU advancement, we’ll spend more time than usual discussing under-the-hood details and tech specs.

Oh, and did I mention all the new features and performance-enhancing software landing alongside the GTX 1080?
On top of all that, Nvidia invested significantly in the new Pascal architecture itself, particularly in tweaking efficiencies to increase clock speeds while simultaneously reducing power requirements, as well as many more under-the-hood goodies that we’ll get to later-including enhanced asynchronous compute features that should help Nvidia’s cards perform better in DirectX 12 titles and combat a major Radeon advantage. Pascal GPUs adopted the advanced FinFET “3D” transistor technology that made its first mainsteam appearance in Intel’s Ivy Bridge computer processors, and the GTX 1080 is the first graphics card powered by GDDR5X memory, a supercharged new version of the GDDR5 memory that’s come standard in graphics cards for a few years now. That’s nuts, and it alone could create a big theoretical jump in performance.
