Nvidia details OEM version of GeForce GTX 660

Nvidia released the GeForce GTX 660 Ti less than one week ago. Now, the company's website has added specifications for an "OEM" derivative of the card. Meant for system builders, the GeForce GTX 660 (OEM) appears to be based on the same GK104 GPU as its Ti sibling. While the Ti disables one of that chip's eight SMX units, the GTX 660's 1152 shader ALUs suggest the lights have been turned off on two SMX engines. Nvidia's product page makes no mention of whether the number of ROP partitions has changed, though. The GeForce GTX 660 Ti uses three of the four ROP partitions on the GK104, and I'd expect the same number to be active in the OEM card.
