Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce GTX 465		200 Watts
	Difference: 140 Watts (233%)

Memory Bandwidth

In theory, the GeForce GTX 465 will be 19% faster than the GeForce GTX 750 Ti in general, because of its higher data rate. (explain)

GeForce GTX 465		102592 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 16192 (19%)

Texel Rate

The GeForce GTX 750 Ti will be quite a bit (about 53%) faster with regards to AF than the GeForce GTX 465. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 14092 (53%)

Pixel Rate

The GeForce GTX 465 should be just a bit (more or less 19%) more effective at AA than the GeForce GTX 750 Ti, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 3104 (19%)

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 information (in units of megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
