Elsewhere though it's generally only a few FPS on average quicker than the top AMD card.
Indeed, in the Company of Heroes 2 test the second-tier Hawaii card beats this GPU behemoth. Temperature performance - GPU 100% - Degrees Centigrade: lower is betterĪt stock speeds the performance lead isn't really that great compared with the R9 290X and even the straight R9 290. When you overclock though the top-end GK 110 chip really stretches its legs.Ĭompany of Heroes 2 - Avg. At those speeds it doesn't look like the extra money you're spending makes much difference at all. When you just take the GTX 780 Ti at stock speeds it can claim the top performance crown overall, but just not by much. The GTX 780 Ti is a hugely desirable card.
If not we'll either see very few of these impressively powerful cards in the wild, or Nvidia is taking a massive hit on each one just to be able to say it's got the fastest single-GPU card in the world. Fingers crossed, now the production process is more mature, the yields on these top chips are much improved. The GTX 780 Ti then comes with 2,880 of those CUDA cores in that fifteen SMX configuration.

The decision was taken to go with just 14 SMX modules in exchange for being able to produce lots of the beefy 28nm processors.īut history has a tendency, despite our best efforts, of repeating itself and as AMD suddenly reclaimed the performance lead in the single-GPU graphics game Nvidia has responded with the full weight of its Kepler architecture. Nvidia could make the full fat chips, but not in any commercially achievable numbers when it first started manufacturing the Kepler graphics processors. Doing the mathematics that meant there should be a chip around with all 2,880 CUDA cores which would be capable of throwing around polygons at breakneck speeds.Īs ever though yields were a problem. The graphics processor at the heart of both the Tesla K20X and the GTX Titan contained 2,688 CUDA cores spread across fourteen SMX modules, but the full GK 110 GPU was designed to house fifteen of those Kepler streaming microprocessors with 192 CUDA cores in each.
Full-fat Keplerīut the GK 110 GPU the Titan was sporting still wasn't representative of the full power of the Kepler architecture. Despite the massive 533m2 slice of silicon it still managed to run relatively cool and very quiet – this was mostly down to the beautiful chrome-plated cooler Nvidia pimped its top card out with.Īs well as giving the Titan an immediately recognisable and desirable design it also provided a much better user experience than the admittedly quicker GTX 690 and later the HD 7990 dual-GPU cards. It wasn't just the performance of the Titan though that singled it out against the competition.
