Radeon HD 4750 vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which features clock speeds of 715 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 4750 should be a lot faster than the Radeon R7 M260 in general. (explain)

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

Texel Rate

The Radeon HD 4750 will be much (more or less 36%) more effective at texture filtering than the Radeon R7 M260. (explain)

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

Pixel Rate

The Radeon HD 4750 should be much (about 104%) better at anti-aliasing than the Radeon R7 M260, and should be able to handle higher resolutions without losing too much performance. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
