	Difference: 57600 (200%)

Texel Rate

The GeForce GTX 650 Ti 2GB is a lot (more or less 430%) more effective at texture filtering than the GeForce GT 430 1GB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 48192 (430%)

Pixel Rate

The GeForce GTX 650 Ti 2GB should be quite a bit (about 430%) faster with regards to AA than the GeForce GT 430 1GB, and also capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 12048 (430%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 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 high resolutions.

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

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