GeForce 9800 GX2 vs Radeon HD 5850

Intro

The GeForce 9800 GX2 comes with a GPU core clock speed of 600 MHz, and the 512 MB of GDDR3 RAM runs at 1000 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare that to the Radeon HD 5850, which features a core clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is made up of 1440(288x5) SPUs, 72 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5850 151 Watts
GeForce 9800 GX2 197 Watts
Difference: 46 Watts (30%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The GeForce 9800 GX2 is quite a bit (about 47%) more effective at AF than the Radeon HD 5850. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
Radeon HD 5850 52200 Mtexels/sec
Difference: 24600 (47%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 5850 is a better choice, by a large margin. (explain)

Radeon HD 5850 23200 Mpixels/sec
GeForce 9800 GX2 19200 Mpixels/sec
Difference: 4000 (21%)

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 transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
