The GPU clockspeed is said to be 875MHz, and two select vendors (ASUS and EVGA) will be allowed to custom clock the card. The ASUS card for instance is rumored to have a clockspeed of 915MHz. Other leaked details reveal the card has 6GB GDDR5 memory clocked at 6008MHz and a 384-bit memory bus.
The board itself follows the design language introduced by GeForce GTX 690, so you can expect rich use of magnesium alloy to make the product look special. Images we saw showed uncanny resemblance to the GTX 690, as the shroud covers the card from front and back. However, the new branding is very much present. If you are interested in color coding, the board is metallic silver / grey with a black PCB, so good luck in finding the matching components.Raw computing power is estimated to be around 4.7 teraflops for single-precision, and double-precision should come in around 196 gigaflops.
The gaming performance of the card is expected to be much higher than that of a GeForce GTX 680, but not enough to beat the GeForce GTX 690 or AMD Radeon HD 7990. Preliminary result indicate the card scores 4870 in 3DMark Fire Strike (Extreme), just 10 percent less than two GeForce GTX 680s in SLI.
NVIDIA's GeForce Titan will not be a mainstream consumer part though, the pricing will likely be very high and according to the rumor, less than 10,000 models will be made.
