The headlines are clear enough. Requiring a mere 180W, and using just a single eight-pin PCI Express power input, the GeForce GTX 1080 offers a 25 to 30 per cent increase in overall performance compared to Titan X, combined with a 28 per cent reduction in TDP. It is the fastest graphics card on the market by a significant margin, and our testing essentially confirms Nvidia's chucklesome claims of "irresponsible levels of performance".
The GTX 1080 achieves its remarkable performance through a combination of factors: Nvidia's engineers have handed in another exemplary optimisation drive, allowing for clock-speeds over 30 per cent faster than the 900 series. This works in combination with the drop to the 16nm FinFET chip process, meaning that the same slice of silicon hosts a 2x increase in transistor density compared to the 28nm technology utilised on previous GPUs from 2011 onwards.
There are some useful new hardware enhancements too. On the media side, Nvidia's already impressive 4K and next-gen codec support gets a boost with support for 12-bit/10-bit HEVC decode plus 10-bit encode, on top of new security protocols added for top-tier media streaming. On top of that, the Polymorph engine gets a 4.0 upgrade, allowing for new functionality called simultaneous multi-projection.
