Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 4750 should be 220% quicker than the Radeon R7 M260 overall, because of its greater data rate. (explain)

Radeon HD 4750		51200 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 35200 (220%)

Texel Rate

The Radeon HD 4750 will be a lot (about 36%) better at AF than the Radeon R7 M260. (explain)

Radeon HD 4750		23360 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 6200 (36%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 4750 is superior to the Radeon R7 M260, by a large margin. (explain)

Radeon HD 4750		11680 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 5960 (104%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
