GeForce GT 430 vs Radeon HD 5670

Intro

Compare that to the Radeon HD 5670, which features core clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 400(80x5) SPUs along with 20 TAUs and 8 ROPs.

GeForce GT 430		60 Watts
Radeon HD 5670		61 Watts
	Difference: 1 Watts (2%)

Memory Bandwidth

As far as performance goes, the Radeon HD 5670 should theoretically be much superior to the GeForce GT 430 in general. (explain)

Radeon HD 5670		64000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 35200 (122%)

Texel Rate

The Radeon HD 5670 is much (about 38%) faster with regards to AF than the GeForce GT 430. (explain)

Radeon HD 5670		15500 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 4300 (38%)

Pixel Rate

The Radeon HD 5670 is quite a bit (more or less 121%) faster with regards to AA than the GeForce GT 430, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 5670		6200 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 3400 (121%)

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: Bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
