Radeon HD 6950 vs Radeon R9 M395X

Intro

The Radeon HD 6950 comes with a core clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It features 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Compare all that to the Radeon R9 M395X, which makes use of a 28 nm design. AMD has set the core speed at 723 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M395X 125 Watts
Radeon HD 6950 200 Watts
Difference: 75 Watts (60%)

Memory Bandwidth

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

Texel Rate

The Radeon R9 M395X will be quite a bit (approximately 31%) better at anisotropic filtering than the Radeon HD 6950. (explain)

Radeon R9 M395X 92544 Mtexels/sec
Radeon HD 6950 70400 Mtexels/sec
Difference: 22144 (31%)

Pixel Rate

The Radeon HD 6950 should be just a bit (about 11%) better at FSAA than the Radeon R9 M395X, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon HD 6950 25600 Mpixels/sec
Radeon R9 M395X 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 data (counted in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
