EXPReview accidentally posted the review of GeForce GTX 780 from Inno3D, including specifications and benchmark of the card.
Its confirmed most of the speculative and leaked information about GTX 780 which will be released shortly. The card does use GK110 core with 2304 CUDA cored with 3GB GDDR5 running at 6 GHz, with a reference clock of 863 MHz and boost of up to 902 MHz and uses 384 bit interface.
It does have 6+8 PCIe pin to draw power, but the following graphs show that this isn’t the case.
The GPU does performance 27% more than GTX 680 and has about 22% performance boost over AMD Radeon HD 7970 GHz Edition.
Its also been shown that GTX Titan has 8.5% advantage over GTX 780 in benchmarks that included 3DMark 11, 3DMark’s FireStrike and FS Xtreme presets, Unigine Heaven 4.0, Valley 4.0, Batman: Arkham City, COD: Black Ops 2, Crysis 3, Dirt 3, Resident Evil 6, Sleeping Dogs, Tomb Raider, Metro: Last Light, Luxmark 2.0 and Computemark.
Temperature wise, the card seems cooler than Titan on idle but on load it goes head-to-head with Titan at 80 degrees with even 3 degrees Celcius more when checked with Furmark, but it should be noted that Inno3D uses their own cooler design and not the reference version.
When it comes to power consumption, on idle while it does consume 70 W, with Furmark putting the card in full spin it consumes 354 W, more than the stock version of GTX Titan that consumes 330 W.
