Radeon HD 6750 vs Radeon R7 M265

Intro

Compare all that 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 along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 should perform much faster 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 will be much (approximately 50%) better at texture 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 should be quite a bit (more or less 100%) more effective at full screen anti-aliasing than the Radeon R7 M265, and able to handle 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 largest amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
