GeForce GTX 480 vs Radeon HD 4350

Intro

Compare that to the Radeon HD 4350, which comes with core speeds of 575 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 memory. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Texel Rate

The GeForce GTX 480 will be quite a bit (more or less 813%) more effective at AF than the Radeon HD 4350. (explain)

GeForce GTX 480		42000 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 37400 (813%)

Pixel Rate

The GeForce GTX 480 will be a lot (about 1361%) better at full screen anti-aliasing than the Radeon HD 4350, and able to handle higher resolutions better. (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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
