GeForce 8800 GS vs GeForce GT 320

Intro

Compare all that to the GeForce GT 320, which makes use of a 40 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 memory is set to run at a frequency of 790 MHz on this particular model. It features 72 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce 8800 GS		105 Watts
	Difference: 62 Watts (144%)

Memory Bandwidth

In theory, the GeForce 8800 GS should perform quite a bit faster than the GeForce GT 320 in general. (explain)

GeForce 8800 GS		38400 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 13120 (52%)

Texel Rate

The GeForce 8800 GS is quite a bit (about 104%) faster with regards to texture filtering than the GeForce GT 320. (explain)

GeForce 8800 GS		26400 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 13440 (104%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 8800 GS is superior to the GeForce GT 320, and very much so. (explain)

GeForce 8800 GS		6600 Mpixels/sec
GeForce GT 320		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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
