GeForce GT 320 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 RAM. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Radeon HD 4350		8000 MB/sec
	Difference: 17280 (216%)

Texel Rate

The GeForce GT 320 should be quite a bit (about 182%) more effective at anisotropic filtering than the Radeon HD 4350. (explain)

GeForce GT 320		12960 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 8360 (182%)

Pixel Rate

The GeForce GT 320 is quite a bit (about 88%) more effective at AA than the Radeon HD 4350, and capable of handling higher resolutions better. (explain)

GeForce GT 320		4320 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 2020 (88%)

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 transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at 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 that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
