Expected to launch alongside the GTX 660, Mydrivers.com managed to get their hands on some details and a picture of the upcoming GTX 650 graphics card.
The GTX 650 is expected to be based on the same GK107 chip seen behind the GT 640 graphics card and feature 384 CUDA cores and 16 ROPs. Unlike the GT 640, the GTX 650 GK107 GPU will be paired up 1GB of faster GDDR5 memory. The new GTX 650 graphics card has a 65W TDP and should end up with a similar GPU clock as the GT 640. It will no feature GPU Boost but should hold its ground with 5GHz GDDR5 clocked memory.
According to our info this one should be based on the GK107-450 GPU and should launch alongside the GTX 660. According to early rumors, Nvidia also apparently plans the GTX 650 Ti graphics card based on the GK106 GPU for October.
