GeForce GTX 260 216SP 55 nm vs Radeon HD 5970

Intro

The GeForce GTX 260 216SP 55 nm features clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 216 SPUs along with 72 Texture Address Units and 28 ROPs.

Compare that to the Radeon HD 5970, which comes with a GPU core clock speed of 725 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also features 1600 Stream Processors, 160 TAUs, and 64 ROPs.

Radeon HD 5970 232000 Mtexels/sec
GeForce GTX 260 216SP 55 nm 41472 Mtexels/sec
Difference: 190528 (459%)

Pixel Rate

The Radeon HD 5970 is much (approximately 475%) faster with regards to full screen anti-aliasing than the GeForce GTX 260 216SP 55 nm, and able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 5970 92800 Mpixels/sec
GeForce GTX 260 216SP 55 nm 16128 Mpixels/sec
Difference: 76672 (475%)

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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
