Gigabyte GeForce GTX Titan 6GB Graphics Card Review - PCSTATS.com Gigabyte GeForce GTX Titan 6GB Graphics Card Review
Sat, Mar 16 2013 | 12:03PM | Filed under: Video Cards| PermaLink Posted by: STAFF

The card has been named after what is currently the worlds fastest super computer - 'Titan' - a behemoth of technological engineering, packing in 18688 AMD Opteron 6274 16-core CPUs, 18688 Tesla K20X GPUs, 710TB of total memory, 10PB of storage, an a theoretical peak speed of 27petaFLOPS. The Cray supercomputer which consumes a whopping 8.2MW of power costs a total of $97 million and resides at the Oak Ridge National Labratory. We saw a few of the Titan's highlights mentioned last week when NVIDIA lifted the NDA on the cards specifications, but to refresh ourselves on these, the single core design houses 2,688 CUDA cores and 7.1 billion transistors and runs at a speed of 837MHz boosting to 876MHz - this is topped with 6GB of GDDR5 memory. A key feature that we will point out that is new to Titan over any other NVIDIA GPU is GPU Boost 2.0. This works in a similar way to how GPU Boost operates on other cards, however rather than limiting the cards overclock to staying within a certain power envelope, GPU Boost 2.0 now allows to card to go even further and overclocks the card dynamically whilst keeping it under 80 degrees Celsius. This in effect means that the card will be able to overclock itself to a higher speed and since the temperature is linked directly to the vCore, the board and adjust the voltages more accurately and higher at the same time to keep the card stable. This is not where the new features end, there is also display overclocking, a concept that allow most monitors to display frame rates higher than they typically would be able to under normal circumstances. Typically most displays run at 60Hz, although there are a number that can run at 120Hz (normally 3D enabled panels) and to put this into frame rates, 60Hz = 60fps, so whilst the card is able to push out far more than this, the panel will only display at its refresh rate. What the Titan is able to do however is overclock the refresh rate of the screen and by increasing the frequency to say 80Hz, the screen will now actually display more frames each second to give a smoother image.
