Radeon HD 5970 vs Radeon HD 6950 2GB

Intro

The Radeon HD 5970 has a GPU clock speed of 725 MHz, and the 1024 MB of GDDR5 memory runs at 1000 MHz through a 256-bit bus. It also is made up of 1600 Stream Processors, 160 TAUs, and 64 ROPs.

Compare that to the Radeon HD 6950 2GB, which uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this specific card. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

Radeon HD 6950 2GB 160000 MB/sec
Difference: 96000 (60%)

Texel Rate

The Radeon HD 5970 is a lot (about 230%) faster with regards to anisotropic filtering than the Radeon HD 6950 2GB. (explain)

Radeon HD 5970 232000 Mtexels/sec
Radeon HD 6950 2GB 70400 Mtexels/sec
Difference: 161600 (230%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5970 is a better choice, by far. (explain)

Radeon HD 5970 92800 Mpixels/sec
Radeon HD 6950 2GB 25600 Mpixels/sec
Difference: 67200 (263%)

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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 get to the maximum fill rate.
