GeForce 9800 GX2 vs GeForce GTX 275

Intro

The GeForce 9800 GX2 has a GPU core clock speed of 600 MHz, and the 512 MB of GDDR3 RAM is set to run at 1000 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare that to the GeForce GTX 275, which uses a 55 nm design. nVidia has clocked the core speed at 633 MHz. The GDDR3 RAM is set to run at a speed of 1134 MHz on this particular card. It features 240 SPUs as well as 80 TAUs and 28 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GX2 197 Watts
GeForce GTX 275 219 Watts
Difference: 22 Watts (11%)

Memory Bandwidth

Theoretically, the GeForce 9800 GX2 should be a little bit faster than the GeForce GTX 275 in general. (explain)

GeForce 9800 GX2 128000 MB/sec
GeForce GTX 275 127008 MB/sec
Difference: 992 (1%)

Texel Rate

The GeForce 9800 GX2 will be a lot (about 52%) more effective at anisotropic filtering than the GeForce GTX 275. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
GeForce GTX 275 50640 Mtexels/sec
Difference: 26160 (52%)

Pixel Rate

The GeForce 9800 GX2 is just a bit (approximately 8%) better at FSAA than the GeForce GTX 275, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
GeForce GTX 275 17724 Mpixels/sec
Difference: 1476 (8%)

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 MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 bandwidth is, the lower the potential to reach the max fill rate.
