Radeon HD 6570 (OEM) 1GB		28800 MB/sec
GeForce 9600 GSO ASUS 512		16000 MB/sec
	Difference: 12800 (80%)

Texel Rate

The GeForce 9600 GSO ASUS 512 should be much (more or less 69%) faster with regards to anisotropic filtering than the Radeon HD 6570 (OEM) 1GB. (explain)

GeForce 9600 GSO ASUS 512		26400 Mtexels/sec
Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
	Difference: 10800 (69%)

Pixel Rate

The GeForce 9600 GSO ASUS 512 will be quite a bit (approximately 27%) faster with regards to anti-aliasing than the Radeon HD 6570 (OEM) 1GB, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce 9600 GSO ASUS 512		6600 Mpixels/sec
Radeon HD 6570 (OEM) 1GB		5200 Mpixels/sec
	Difference: 1400 (27%)

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 information (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
