The Radeon R9 M280X is a lot (about 24%) more effective at texture filtering than the GeForce GTX 750 Ti. (explain)

Radeon R9 M280X		50400 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 9600 (24%)

Pixel Rate

The GeForce GTX 750 Ti is just a bit (approximately 13%) better at full screen anti-aliasing than the Radeon R9 M280X, and should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon R9 M280X		14400 Mpixels/sec
	Difference: 1920 (13%)

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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
