GeForce 9600 GSO ASUS 512 vs GeForce GTX 570

Intro

Compare all that to the GeForce GTX 570, which features a clock frequency of 732 MHz and a GDDR5 memory speed of 950 MHz. It also makes use of a 320-bit bus, and uses a 40 nm design. It is made up of 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.

The GeForce GTX 570 is much (approximately 66%) more effective at texture filtering than the GeForce 9600 GSO ASUS 512. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce 9600 GSO ASUS 512		26400 Mtexels/sec
	Difference: 17520 (66%)

Pixel Rate

The GeForce GTX 570 should be a lot (more or less 344%) more effective at AA than the GeForce 9600 GSO ASUS 512, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce 9600 GSO ASUS 512		6600 Mpixels/sec
	Difference: 22680 (344%)

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 max amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling 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 can possibly write to its 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
