Radeon HD 6950 vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 6950 should be much faster than 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 is a lot (more or less 256%) more effective at AF than the Radeon R7 M260X. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 6950 is a better choice, by far. (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 maximum amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out 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 video 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 record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
