Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 3470 256MB should theoretically be a little bit superior to the GeForce GT 430 in general. (explain)

Radeon HD 3470 256MB 30400 MB/sec
GeForce GT 430 28800 MB/sec
Difference: 1600 (6%)

Texel Rate

The GeForce GT 430 will be quite a bit (about 250%) faster with regards to anisotropic filtering than the Radeon HD 3470 256MB. (explain)

GeForce GT 430 11200 Mtexels/sec
Radeon HD 3470 256MB 3200 Mtexels/sec
Difference: 8000 (250%)

Pixel Rate

The Radeon HD 3470 256MB is a bit (about 14%) faster with regards to FSAA than the GeForce GT 430, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 3470 256MB 3200 Mpixels/sec
GeForce GT 430 2800 Mpixels/sec
Difference: 400 (14%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 can be processed per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
