GeForce GT 430 (OEM) vs Radeon HD 5570

Intro

Compare that to the Radeon HD 5570, which makes use of a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 RAM works at a frequency of 900 MHz on this specific model. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.

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 the same. (explain)

Texel Rate

The Radeon HD 5570 is a little bit (about 16%) more effective 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 high levels of AA is important to you, then the Radeon HD 5570 is a better choice, by a large margin. (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 data (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
