GeForce 9600 GSO 768MB vs GeForce GTX 465

Intro

Compare those specifications to the GeForce GTX 465, which uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM runs at a speed of 802 MHz on this specific model. It features 352 SPUs along with 44 Texture Address Units and 32 ROPs.

GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 308 (1%)

Pixel Rate

The GeForce GTX 465 should be quite a bit (approximately 194%) better at full screen anti-aliasing than the GeForce 9600 GSO 768MB, and also capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 12824 (194%)

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 data (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
