Radeon HD 4350 vs Radeon HD 5570

Intro

Compare all of that to the Radeon HD 5570, which has core clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 RAM. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

The Radeon HD 5570 will be quite a bit (more or less 183%) faster with regards to AF than the Radeon HD 4350. (explain)

Radeon HD 5570		13000 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 8400 (183%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5570 is a better choice, by far. (explain)

Radeon HD 5570		5200 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 2900 (126%)

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 max amount of information (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per 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 clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
