Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 750 Ti will be 20% quicker than the Radeon R9 M265X overall, due to its higher data rate. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 750 Ti is a lot (approximately 77%) faster with regards to AF than the Radeon R9 M265X. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 17800 (77%)

Pixel Rate

The GeForce GTX 750 Ti will be quite a bit (more or less 77%) faster with regards to full screen anti-aliasing than the Radeon R9 M265X, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 7120 (77%)

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 (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better 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 number of pixels the graphics card can possibly write to its 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
