Radeon HD 5970 vs Radeon HD 6990

Intro

The Radeon HD 5970 uses a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this card. It features 1600 SPUs as well as 160 TAUs and 64 Rasterization Operator Units.

Compare all that to the Radeon HD 6990, which has core clock speeds of 830 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs along with 96 Texture Address Units and 32 Rasterization Operator Units.

Radeon HD 5970 256000 MB/sec
Difference: 64000 (25%)

Texel Rate

The Radeon HD 5970 is a lot (approximately 46%) faster with regards to AF than the Radeon HD 6990. (explain)

Radeon HD 5970 232000 Mtexels/sec
Radeon HD 6990 159360 Mtexels/sec
Difference: 72640 (46%)

Pixel Rate

The Radeon HD 5970 is a lot (more or less 75%) more effective at anti-aliasing than the Radeon HD 6990, and also should be capable of handling higher screen resolutions better. (explain)

Radeon HD 5970 92800 Mpixels/sec
Radeon HD 6990 53120 Mpixels/sec
Difference: 39680 (75%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure 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 video 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 most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of 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 rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

This is wrong! The 6990 has 192 texture units and the 5970 has 160 texture units. They have the same amount of render output units or ROPs.
