The GTX 780 has the same PCB as the GTX TITAN. It doesn’t seem like NVIDIA altered the layout of the board in any way, in fact the most distinctive parts are missing memory chips on the PCB. The GTX 780 has 6+2 phase design. Apart from that, there are at least two very small changes with the components. The green and red blocks show the actual difference between the GTX 780 and GTX TITAN. The orange block represents the dissimilarity between the TITAN engineering samples from the reviews and the GTX 780 PCB from it168 (this change is not seen on retail TITAN’s proof). Take a look for yourself in this image:

GeForce GTX 780 is using a GK110-300-A1 GPU. The processor is equipped with2304 CUDA cores, 192 texture mapping units and 48 raster operating units. It comes with 3GB GDDR5 memory across a 384-bit interface. All memory chips are situated on the top of the board, which is not surprising at all. The card is clocked at base 863 MHz with a boost to 902 MHz. The memory is running at the same speed as TITAN’s — 1502MHz which is an effective speed of 6008MHz. The TDP remains the same as Titan at 250W. The power is drawn through 6+8pin power connectors. There are two SLI connectors, so a maximum of four can be put in SLI.

So you probably want to see the card itself, right? Well, here you go… enjoy!
