GeForce 9800 GX2 vs Radeon HD 6750

Intro

The GeForce 9800 GX2 features clock speeds of 600 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 memory. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon HD 6750, which has a clock frequency of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 720 SPUs, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750 86 Watts
GeForce 9800 GX2 197 Watts
Difference: 111 Watts (129%)

Memory Bandwidth

In theory, the GeForce 9800 GX2 will be 100% quicker than the Radeon HD 6750 in general, because of its higher bandwidth. (explain)

GeForce 9800 GX2 128000 MB/sec
Radeon HD 6750 64000 MB/sec
Difference: 64000 (100%)

Texel Rate

The GeForce 9800 GX2 is a lot (more or less 194%) more effective at AF than the Radeon HD 6750. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
Radeon HD 6750 26100 Mtexels/sec
Difference: 50700 (194%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 9800 GX2 is the winner, and very much so. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
Radeon HD 6750 11600 Mpixels/sec
Difference: 7600 (66%)

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 data (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 are applied in one second. This number is worked out by multiplying the total amount of 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
