GeForce 9600 GSO 768MB vs GeForce GTX 465

Intro

Compare those specs to the GeForce GTX 465, which features a GPU core clock speed of 607 MHz, and 1024 MB of GDDR5 RAM set to run at 802 MHz through a 256-bit bus. It also features 352 Stream Processors, 44 Texture Address Units, and 32 Raster Operation Units.

	Difference: 308 (1%)

Pixel Rate

The GeForce GTX 465 will be much (more or less 194%) better at AA than the GeForce 9600 GSO 768MB, and also will be able to handle higher screen resolutions more effectively. (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 (in units of megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling 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 the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
