Nvidia has detailed its latest high end graphics card, the GTX Titan, confirming its existence with some impressive numbers that should cement its position as the world's fastest GPU.

Built around the GK110 Tesla technology first used in the Titan supercomputer - hence the name - the GTX Titan is Nvidia's most powerful graphics card to date, with a whopping 2,688 CUDA cores and 7.1 billion transistors, which produce 4,500 Gigaflops of processing power. Each card comes with 6GB of GDDR5 RAM, running along a 384-bit interface which should be more than sufficient for playing the latest games at above HD resolution. It's DirextX 11.1 compatible, so

Perhaps more exciting news is the addition of GPU Boost 2.0, an evolution of the software introduced with Nvidia's 600-series graphics cards. Built into the video driver, GPU Boost 2.0 will let Titan owners overclock and olvervolt their cards, with higher limits than with previous cards and optimisations for water-cooling setups.

It will also allow you to "overclock" your display, running it at a faster sync rate than it officially supports to squeeze out some extra frames per second. As an example, a monitor rated for 60Hz refresh only could run at up to 80Hz, meaning twenty extra frames per second are being displayed.

The one sticking price will almost certainly be the price - Nvidia would only confirm RRP pricing with us today, as it will be up to its hardware partners to set their own prices when the cards launch later this week, but you'll easily be paying over £800 per card. We'll have to wait until then to see whether the benchmark scores can back up Nvidia's claims that the Titan is the fastest card around, but the early indications look promising.
