GeForce 8600 GT 256MB DDR2 vs GeForce 9600 GSO ASUS 512

Intro

The GeForce 8600 GT 256MB DDR2 features a core clock frequency of 540 MHz and a DDR2 memory speed of 400 MHz. It also features a 128-bit memory bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.

Compare all of that to the GeForce 9600 GSO ASUS 512, which comes with GPU core speed of 550 MHz, and 512 MB of DDR2 RAM running at 500 MHz through a 128-bit bus. It also features 96 SPUs, 48 Texture Address Units, and 12 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 256MB DDR2 47 Watts
GeForce 9600 GSO ASUS 512 84 Watts
Difference: 37 Watts (79%)

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GSO ASUS 512 should be 25% faster than the GeForce 8600 GT 256MB DDR2 in general, because of its greater data rate. (explain)

GeForce 9600 GSO ASUS 512 16000 MB/sec
GeForce 8600 GT 256MB DDR2 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The GeForce 9600 GSO ASUS 512 will be quite a bit (more or less 206%) more effective at texture filtering than the GeForce 8600 GT 256MB DDR2. (explain)

GeForce 9600 GSO ASUS 512 26400 Mtexels/sec
GeForce 8600 GT 256MB DDR2 8640 Mtexels/sec
Difference: 17760 (206%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9600 GSO ASUS 512 is a better choice, and very much so. (explain)

GeForce 9600 GSO ASUS 512 6600 Mpixels/sec
GeForce 8600 GT 256MB DDR2 4320 Mpixels/sec
Difference: 2280 (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling 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 that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
