Radeon HD 6750 1GB vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which has GPU core speed of 825 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon HD 6750 1GB is much (approximately 32%) better at AF than the Radeon R7 M260X. (explain)

Radeon HD 6750 1GB		26100 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 6300 (32%)

Pixel Rate

The Radeon HD 6750 1GB is much (more or less 76%) more effective at AA than the Radeon R7 M260X, and should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 5000 (76%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
