GeForce 9600 GSO 768MB vs GeForce GT 320

Intro

Compare those specs to the GeForce GT 320, which uses a 40 nm design. nVidia has clocked the core speed at 540 MHz. The GDDR3 memory is set to run at a frequency of 790 MHz on this particular card. It features 72 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce 9600 GSO 768MB		84 Watts
	Difference: 41 Watts (95%)

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GSO 768MB should be 52% quicker than the GeForce GT 320 in general, due to its greater bandwidth. (explain)

GeForce 9600 GSO 768MB		38400 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 13120 (52%)

Texel Rate

The GeForce 9600 GSO 768MB will be quite a bit (more or less 104%) better at AF than the GeForce GT 320. (explain)

GeForce 9600 GSO 768MB		26400 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 13440 (104%)

Pixel Rate

The GeForce 9600 GSO 768MB should be much (approximately 53%) faster with regards to full screen anti-aliasing than the GeForce GT 320, and will be capable of handling higher screen resolutions more effectively. (explain)

GeForce 9600 GSO 768MB		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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at 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 the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
