GeForce 9600 GSO 768MB vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which features core speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 18960 (72%)

Pixel Rate

The GeForce GTX 560 should be quite a bit (more or less 293%) faster with regards to FSAA than the GeForce 9600 GSO 768MB, and also capable of handling higher screen resolutions better. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 19320 (293%)

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 largest amount of information (in units of MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
