GeForce 8800 GTS (G80) 320MB vs GeForce 9600 GT 1GB

Intro

The GeForce 8800 GTS (G80) 320MB comes with clock speeds of 513 MHz on the GPU, and 792 MHz on the 320 MB of GDDR3 RAM. It features 96 SPUs along with 48 TAUs and 20 ROPs.

Compare that to the GeForce 9600 GT 1GB, which has GPU core speed of 650 MHz, and 1024 MB of GDDR3 memory running at 900 MHz through a 256-bit bus. It also is made up of 64 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 1GB 95 Watts
GeForce 8800 GTS (G80) 320MB 143 Watts
Difference: 48 Watts (51%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GTS (G80) 320MB should be 10% quicker than the GeForce 9600 GT 1GB overall, because of its higher data rate. (explain)

GeForce 8800 GTS (G80) 320MB 63360 MB/sec
GeForce 9600 GT 1GB 57600 MB/sec
Difference: 5760 (10%)

Texel Rate

The GeForce 8800 GTS (G80) 320MB is a small bit (approximately 18%) better at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)

GeForce 8800 GTS (G80) 320MB 24624 Mtexels/sec
GeForce 9600 GT 1GB 20800 Mtexels/sec
Difference: 3824 (18%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9600 GT 1GB is a better choice, though only just barely. (explain)

GeForce 9600 GT 1GB 10400 Mpixels/sec
GeForce 8800 GTS (G80) 320MB 10260 Mpixels/sec
Difference: 140 (1%)

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 largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
