Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB		110 Watts
GeForce GTX 260		182 Watts
	Difference: 72 Watts (65%)

Memory Bandwidth

Theoretically, the GeForce GTX 260 should be a lot faster than the GeForce GTX 650 Ti 2GB overall. (explain)

GeForce GTX 260		111888 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 25488 (30%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be quite a bit (about 61%) better at texture filtering than the GeForce GTX 260. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 22528 (61%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 260 is superior to the GeForce GTX 650 Ti 2GB, but it probably won't make a huge difference. (explain)

GeForce GTX 260		16128 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 1280 (9%)

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 max amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
