GeForce 9800 GX2 vs Radeon HD 5970

Intro

The GeForce 9800 GX2 features a core clock speed of 600 MHz and a GDDR3 memory frequency of 1000 MHz. It also uses a 256-bit bus, and makes use of a 65 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 ROPs.

Compare those specs to the Radeon HD 5970, which comes with a GPU core clock speed of 725 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also features 1600 SPUs, 160 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GX2 197 Watts
Radeon HD 5970 294 Watts
Difference: 97 Watts (49%)

Memory Bandwidth

In theory, the Radeon HD 5970 should be 100% faster than the GeForce 9800 GX2 in general, because of its higher data rate. (explain)

Radeon HD 5970 256000 MB/sec
GeForce 9800 GX2 128000 MB/sec
Difference: 128000 (100%)

Texel Rate

The Radeon HD 5970 is quite a bit (more or less 202%) more effective at anisotropic filtering than the GeForce 9800 GX2. (explain)

Radeon HD 5970 232000 Mtexels/sec
GeForce 9800 GX2 76800 Mtexels/sec
Difference: 155200 (202%)

Pixel Rate

The Radeon HD 5970 should be quite a bit (approximately 383%) more effective at anti-aliasing than the GeForce 9800 GX2, and able to handle higher resolutions without slowing down too much. (explain)

Radeon HD 5970 92800 Mpixels/sec
GeForce 9800 GX2 19200 Mpixels/sec
Difference: 73600 (383%)

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 maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
