Radeon HD 6970 vs Radeon R9 285

Intro

The Radeon HD 6970 features core clock speeds of 880 MHz on the GPU, and 1375 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs as well as 96 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon R9 285, which has GPU core speed of 918 MHz, and 2048 MB of GDDR5 RAM set to run at 1375 MHz through a 256-bit bus. It also is comprised of 1792 Stream Processors, 112 TAUs, and 32 ROPs.

Power Consumption (Max TDP)

Radeon R9 285 190 Watts
Radeon HD 6970 250 Watts
Difference: 60 Watts (32%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon R9 285 should be much (approximately 22%) faster with regards to anisotropic filtering than the Radeon HD 6970. (explain)

Radeon R9 285 102816 Mtexels/sec
Radeon HD 6970 84480 Mtexels/sec
Difference: 18336 (22%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 285 is a better choice, though not by far. (explain)

Radeon R9 285 29376 Mpixels/sec
Radeon HD 6970 28160 Mpixels/sec
Difference: 1216 (4%)

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 (measured in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at 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 can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
