Radeon HD 6750 vs Radeon R7 M260

Intro

Compare those specs to the Radeon R7 M260, which comes with a GPU core clock speed of 715 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 will be 300% faster than the Radeon R7 M260 overall, because of its greater data rate. (explain)

Radeon HD 6750		64000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon HD 6750 should be a lot (more or less 52%) more effective at AF than the Radeon R7 M260. (explain)

Radeon HD 6750		26100 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 8940 (52%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6750 is a better choice, and very much so. (explain)

Radeon HD 6750		11600 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 5880 (103%)

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: Bandwidth is the largest amount of information (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
