In theory, the GeForce GTX 650 Ti 2GB should be 125% faster than the GeForce 9600 GSO 1.5GB overall, due to its higher data rate. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
GeForce 9600 GSO 1.5GB		38400 MB/sec
	Difference: 48000 (125%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be much (about 125%) more effective at anisotropic filtering than the GeForce 9600 GSO 1.5GB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce 9600 GSO 1.5GB		26400 Mtexels/sec
	Difference: 32992 (125%)

Pixel Rate

The GeForce GTX 650 Ti 2GB will be quite a bit (about 125%) faster with regards to full screen anti-aliasing than the GeForce 9600 GSO 1.5GB, and also capable of handling higher resolutions better. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
GeForce 9600 GSO 1.5GB		6600 Mpixels/sec
	Difference: 8248 (125%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
