GeForce GTX 260 216SP 55 nm vs Radeon HD 5970

Intro

The GeForce GTX 260 216SP 55 nm makes use of a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory runs at a speed of 999 MHz on this particular model. It features 216 SPUs as well as 72 TAUs and 28 Rasterization Operator Units.

Compare all of that to the Radeon HD 5970, which makes use of a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific model. It features 1600 SPUs as well as 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 should be quite a bit (more or less 475%) more effective at FSAA than the GeForce GTX 260 216SP 55 nm, and also capable of handling higher screen 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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
