Radeon HD 6950 vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which comes with core clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 6950 should in theory be a lot superior to the Radeon R7 M260X in general. (explain)

Radeon HD 6950		160000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 96000 (150%)

Texel Rate

The Radeon HD 6950 will be quite a bit (more or less 256%) better at texture filtering than the Radeon R7 M260X. (explain)

Radeon HD 6950		70400 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 50600 (256%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6950 is the winner, by a large margin. (explain)

Radeon HD 6950		25600 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 19000 (288%)

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 (measured in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
