Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M390X 125 Watts
Radeon HD 6950 2GB 200 Watts
Difference: 75 Watts (60%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The Radeon R9 M390X will be quite a bit (more or less 31%) more effective at AF than the Radeon HD 6950 2GB. (explain)

Radeon R9 M390X 92544 Mtexels/sec
Radeon HD 6950 2GB 70400 Mtexels/sec
Difference: 22144 (31%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6950 2GB is superior to the Radeon R9 M390X, but only just. (explain)

Radeon HD 6950 2GB 25600 Mpixels/sec
Radeon R9 M390X 23136 Mpixels/sec
Difference: 2464 (11%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
