Thanks to Xylene from Overclock.net we are able to see the first pictures of the NVIDIA GeForce GTX 660 Ti’s PCB.

While the full cards takes 9.5 inches, the PCB is only 6.75″, which is 3.25″ shorter than GTX 680′s. The GTX 660 Ti’s board is almost the same as GTX 670′s. For a card that requires only 150 Watts the cooler is sufficient enough. Actually it was already with GTX 670.

In comparison to GTX 680 board we can notice that the VRM circuitry has been moved to the front, while the GPU and memory are situated in the middle of the card (with cooler). On the top of the card we notice two SLI connectors, which will support 3-way configuration.

The same as GTX 670, the new model has PEG connectors placed in the middle of the whole card – quite distinctive part of the reference design.

The reference board holds eight Hynix memory chips, from which two are located on the back. Card is using a 4+2 phase power design (4 for the GPU and 2 for memory).

In overall it’s very hard to notice any change to the PCB. There are few components located elsewhere on the back (including missing memory slots), this is possibly related to the lower requirements of the shorter memory interface (or just a new revision of the whole board). Basically this means that NVIDIA is offering both cards on the same PCB (with cosmetic changes). This could help the company save lot’s of money, while their engineers did not have to design a completely new PCB.

Thanks to my remarkable Photoshop skills you can see both PCB’s and compare them by yourself.
