Radeon HD 6750 vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which comes with clock speeds of 725 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 6750 should theoretically be a lot better than the Radeon R7 M265 in general. (explain)

Radeon HD 6750		64000 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 32000 (100%)

Texel Rate

The Radeon HD 6750 is quite a bit (approximately 50%) better at anisotropic filtering than the Radeon R7 M265. (explain)

Radeon HD 6750		26100 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 8700 (50%)

Pixel Rate

The Radeon HD 6750 will be much (more or less 100%) more effective at anti-aliasing than the Radeon R7 M265, and also capable of handling higher resolutions without slowing down too much. (explain)

Radeon HD 6750		11600 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 5800 (100%)

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 (counted in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
