GeForce GTX 470 vs Radeon HD 5970

Intro

The GeForce GTX 470 features a GPU core speed of 607 MHz, and the 1280 MB of GDDR5 memory is set to run at 837 MHz through a 320-bit bus. It also is comprised of 448 SPUs, 56 TAUs, and 40 ROPs.

Compare all that to the Radeon HD 5970, which comes with a clock frequency of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It features 1600 SPUs, 160 TAUs, and 64 ROPs.

GeForce GTX 470 133920 MB/sec
Difference: 122080 (91%)

Texel Rate

The Radeon HD 5970 is a lot (approximately 583%) faster with regards to AF than the GeForce GTX 470. (explain)

Radeon HD 5970 232000 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 198008 (583%)

Pixel Rate

If running with 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
GeForce GTX 470 24280 Mpixels/sec
Difference: 68520 (282%)

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 (measured in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
