GeForce 9600 GSO 512MB vs Radeon HD 4750

Intro

Compare that to the Radeon HD 4750, which features core clock speeds of 730 MHz on the GPU, and 800 MHz on the 512 MB of GDDR5 RAM. It features 640(128x5) SPUs along with 32 TAUs and 16 ROPs.

Radeon HD 4750		51200 MB/sec
	Difference: 6400 (13%)

Texel Rate

The GeForce 9600 GSO 512MB will be much (approximately 34%) better at texture filtering than the Radeon HD 4750. (explain)

GeForce 9600 GSO 512MB		31200 Mtexels/sec
Radeon HD 4750		23360 Mtexels/sec
	Difference: 7840 (34%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 4750 is the winner, not by a very large margin though. (explain)

Radeon HD 4750		11680 Mpixels/sec
GeForce 9600 GSO 512MB		10400 Mpixels/sec
	Difference: 1280 (12%)

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 MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core 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 output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
