GeForce GT 430 (OEM) vs Radeon HD 5570

Intro

Compare all that to the Radeon HD 5570, which features clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 RAM. It features 400(80x5) SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
GeForce GT 430 (OEM)		60 Watts
	Difference: 17 Watts (40%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon HD 5570 is just a bit (more or less 16%) better at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

Radeon HD 5570		13000 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 1800 (16%)

Pixel Rate

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

Radeon HD 5570		5200 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 2400 (86%)

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 MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
