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

Texel Rate

The GeForce GTX 650 Ti 2GB is a lot (about 61%) better at AF 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

The GeForce GTX 260 should be a bit (more or less 9%) faster with regards to anti-aliasing than the GeForce GTX 650 Ti 2GB, and should be capable of handling higher resolutions while still performing well. (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 largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
