Radeon HD 4750 vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which comes with core speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should be much faster than the Radeon HD 4750 in general. (explain)

Radeon R7 M260X		64000 MB/sec
Radeon HD 4750		51200 MB/sec
	Difference: 12800 (25%)

Texel Rate

The Radeon HD 4750 will be a bit (approximately 18%) better at AF than the Radeon R7 M260X. (explain)

Radeon HD 4750		23360 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 3560 (18%)

Pixel Rate

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

Radeon HD 4750		11680 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 5080 (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 information (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 number of texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
