GeForce GTX 580 3GB vs Radeon HD 4350

Intro

Compare those specs to the Radeon HD 4350, which makes use of a 55 nm design. AMD has clocked the core speed at 575 MHz. The DDR2 memory is set to run at a frequency of 500 MHz on this specific card. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Radeon HD 4350		4600 Mtexels/sec
	Difference: 44808 (974%)

Pixel Rate

The GeForce GTX 580 3GB is quite a bit (about 1511%) faster with regards to AA than the Radeon HD 4350, and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 580 3GB		37056 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 34756 (1511%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher 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 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. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
