GeForce 9800 GX2 vs GeForce GTX 560 Ti 448

Intro

The GeForce 9800 GX2 has a GPU core speed of 600 MHz, and the 512 MB of GDDR3 memory is set to run at 1000 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Compare that to the GeForce GTX 560 Ti 448, which has GPU clock speed of 732 MHz, and 1280 MB of GDDR5 memory set to run at 900 MHz through a 320-bit bus. It also is comprised of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GX2 197 Watts
GeForce GTX 560 Ti 448 210 Watts
Difference: 13 Watts (7%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti 448 should be 13% quicker than the GeForce 9800 GX2 in general, because of its higher bandwidth. (explain)

GeForce GTX 560 Ti 448 144000 MB/sec
GeForce 9800 GX2 128000 MB/sec
Difference: 16000 (13%)

Texel Rate

The GeForce 9800 GX2 should be a lot (approximately 87%) more effective at anisotropic filtering than the GeForce GTX 560 Ti 448. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
GeForce GTX 560 Ti 448 40992 Mtexels/sec
Difference: 35808 (87%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti 448 is superior to the GeForce 9800 GX2, and very much so. (explain)

GeForce GTX 560 Ti 448 29280 Mpixels/sec
GeForce 9800 GX2 19200 Mpixels/sec
Difference: 10080 (53%)

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 max amount of information (counted in 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 RAM, it should be multiplied by 2 once again. If 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
