GeForce GTX 480 vs Radeon HD 4350

Intro

Compare all that to the Radeon HD 4350, which has a core clock frequency of 575 MHz and a DDR2 memory speed of 500 MHz. It also uses a 64-bit bus, and makes use of a 55 nm design. It features 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

	Difference: 37400 (813%)

Pixel Rate

The GeForce GTX 480 should be quite a bit (approximately 1361%) better at AA than the Radeon HD 4350, and able to handle higher resolutions while still performing well. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 31300 (1361%)

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 megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
