According to Turkish site Donanim Haber, the GTX 650 is positioned above the GT 640, with which it shares the GK107 chip with 384 active processing cores and 1.3 billion transistors. the GK107 is only about 40 percent as large as the GK104 (1,344 cores) that is used, for example, in the previously introduced GTX 670. Pricewise, expect the GTX 650 to find its place much closer to the $100 GT 640 than to the $400 GTX 670. A $120 to $150 range is expected.
The GTX 650 is said to arrive with 1 GB GDDR5 memory, 1 GHz core clock and will become available a little late for the back-to-school season. However, a slight graphics card upgrade may not be on many school supply shopping lists anyway.
