NVIDIA GeForce GTX Titan PCB Pictured...Sort Of
Here's the first blurry picture of the GeForce GTX Titan PCB. Among the structures we can make out on the surprisingly not to busy metropolis is the ASIC itself, which uses an integrated heatspreader much like every other high-end NVIDIA GPU. The card draws power from a combination of 6-pin and 8-pin PCIe power connectors. It is then conditioned to the various power domains by what appears to be an 8+2+2 phase VRM.
One can easily make out 12 memory chips, but that's just on the side that we see. We know for a fact that there are no 4 Gbit GDDR5 memory chips that graphics card makers can buy (at least not at a viable price), and so this card should most definitely use 12 chips on the reverse side.
