In late May Nvidia introduced the GeForce GTX 780 which we called the 'Titan light' since it was based on the same high-end GK110 GPU used in the very expensive GeForce GTX Titan. You can find that original review here. Tests indicated that it was an average of eight per cent slower than the GTX Titan - not bad for a card that costs £548 compared to £900. The GTX 780 gives you really good value for your money in the high-end segment. Only if you need to run professional GPGPU software is the Titan a better option, as Nvidia limited the double precision floating point performance on all other consumer cards. If you plan on gaming only, it's not an issue.
Right after launch we reviewed the Inno3D GeForce GTX 780 iChill, a card that was so overclocked it almost match the GTX Titan on every level. It's available for around £629, so it's obvious we got pretty excited about that card.
We've received more GeForce GTX 780s since then, so today we will compare the Inno3D card with three other GTX 780 cards: the ASUS GTX780-DC2OC-3GD5, the EVGA GeForce GTX 780 ACX Superclocked and the MSI N780 TF 3GD5/OC.
The ASUS GTX780-DC2OC-3GD5 is part of the DirectCU II series. It features a new generation cooler that ASUS probably should have called DirectCU III. A number of things are different compared to existing DirectCU II coolers. For one, the new cooler has extra wide, 10mm heatpipes. When manufacturers transitioned from 6mm heatpipes to 8mm heatpipes, the cooling performance really benefited. So in theory, 10mm heatpipes should be another step up for performance, and our tests prove that it translates to excellent cooling in practice as well.
