Nvidia last week revealed the Geforce GTX780 Ti and the reviews are up.<\/p>\n

The GTX780 Ti is the successor to the GTX 780 and is also technically the successor to the GTX Titan, even though the latter serves a very different purpose in the market thanks to its unlocked double-precision shaders.<\/p>\n

The GTX780 Ti launched at a recommended retail price in the US of $699, making it $150 more than the competing AMD Radeon R9 290X. That translates roughly to R7,200, but it remains to be seen if local suppliers and distributors will be able to approach the same cost in South Africa.<\/p>\n

The GTX780 Ti is the full implementation of Nvidia’s Kepler architecture. It opens up the floodgates for all 2880 CUDA cores, but leaves the double-precision hardware disabled, giving the Titan some breathing room despite it’s high price.<\/p>\n

The GTX780 matches its smaller sibling with the same number of Raster Operators but has a slight boost in texture units, helping it shift more of its weight around at higher resolutions. Clock speeds are also up by a small amount but this is because there are more functional units on the chip itself, increasing power usage and heat generation.<\/p>\n

The memory is the biggest surprise, shipping with the same GDDR5 7.0GHz\u00a0 memory found in the GTX770. Nvidia has had a lot of time to work with and tweak their designs for these chips and most cards will overclock to an incredible 8.0GHz on air cooling alone.<\/p>\n

In terms of compute performance, the GTX780 Ti is below the theoretical peak of the Radeon R9 290X and only a little higher than the GTX Titan. The card should dominate up to 4K resolutions and should see less of a performance hit than the R9 290X once you use games with larger and more complex textures at higher resolutions.<\/p>\n

How it performs<\/h3>\n

In games that are shader-bound (Guild Wars 2), the GTX780 Ti shows a minimal lead over the R9 290X, but in games that use high-resolution textures (Crysis 3) the lead extends quite a bit, in some cases by as much as 10fps at UltraHD 4K resolution.<\/p>\n

Neither the GTX780 Ti or its rival R9 290X are able to consistently provide single-GPU gaming with playable framerates at the 4K resolution, however. Skyrim, Battlefield 3 and Bioshock Infinite are all playable but are also older games based on outdated engines.<\/p>\n

Gaming on a 1080p monitor at 120-144Hz with Lightboost enabled is possible with a single GTX780 Ti. PC Perspective’s tests at 1080p demonstrate this, with some games possibly requiring an overclock to maintain the 120Hz minimum.<\/p>\n\n\t\t
