VS

GeForce 9600 GSO 1.5GB vs GeForce 9800 GX2

Intro

The GeForce 9600 GSO 1.5GB comes with clock speeds of 550 MHz on the GPU, and 800 MHz on the 1536 MB of GDDR3 memory. It features 96 SPUs as well as 48 TAUs and 12 ROPs.

Compare those specifications to the GeForce 9800 GX2, which comes with GPU core speed of 600 MHz, and 512 MB of GDDR3 RAM running at 1000 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GSO 1.5GB 84 Watts
GeForce 9800 GX2 197 Watts
Difference: 113 Watts (135%)

Memory Bandwidth

In theory, the GeForce 9800 GX2 should be 233% quicker than the GeForce 9600 GSO 1.5GB in general, due to its higher data rate. (explain)

GeForce 9800 GX2 128000 MB/sec
GeForce 9600 GSO 1.5GB 38400 MB/sec
Difference: 89600 (233%)

Texel Rate

The GeForce 9800 GX2 will be much (more or less 191%) faster with regards to anisotropic filtering than the GeForce 9600 GSO 1.5GB. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
GeForce 9600 GSO 1.5GB 26400 Mtexels/sec
Difference: 50400 (191%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 9800 GX2 is superior to the GeForce 9600 GSO 1.5GB, and very much so. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
GeForce 9600 GSO 1.5GB 6600 Mpixels/sec
Difference: 12600 (191%)

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 transported over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
