Tom's Hardware published another graphics card roundup
Since our last monthly update, Nvidia launched three new graphics cards: the GeForce GTX 650, 650 Ti, and 660.Best Graphics Cards For The Money: October 2012
The GeForce GTX 650 is essentially a GeForce GT 640 with a higher-clocked 1058 MHz core and 1250 MHz GDDR5 (instead of 891 MHz DDR3 memory). That increased memory bandwidth immediately uncorks this card's performance, putting it head-to-head against the Radeon HD 7750. A $120 price point sounds about right until you hop online and see AMD's Radeon HD 7750 selling for $105. The notably faster Radeon HD 7770 goes for $125. After a series of price drops from AMD, the GeForce GTX 650 needs to get closer to $105 before it's really competitive.
Next, the GeForce GTX 650 Ti is built around the same GK106 GPU found on Nvidia's GeForce GTX 660, but with a single GPC cluster disabled. The result is a processor with 768 shaders, 64 texture units, and two ROP partitions capable of 16 raster operations per clock. The card's core operates at 925 MHz, and its GDDR5 memory runs at 1350 MHz. All told, the GeForce GTX 650 Ti outperforms AMD's Radeon HD 6850 and Nvidia's GeForce GTX 460, nearly reaching the same performance levels as the GeForce GTX 560 and Radeon HD 6870. Unfortunately, a rather narrow 128-bit memory interface hampers frame rates at higher resolutions with MSAA enabled. Nevertheless, GeForce GTX 650 Ti is the highest-performing $150 card on the market.
