GeForce GT 430 1GB vs Radeon HD 3470 256MB

Intro

The GeForce GT 430 1GB comes with a clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Compare that to the Radeon HD 3470 256MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 800 MHz. The DDR2 memory is set to run at a speed of 950 MHz on this particular card. It features 40(8x5) SPUs as well as 4 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3470 256MB will be 6% faster than the GeForce GT 430 1GB overall, because of its higher bandwidth. (explain)

Radeon HD 3470 256MB 30400 MB/sec
GeForce GT 430 1GB 28800 MB/sec
Difference: 1600 (6%)

Texel Rate

The GeForce GT 430 1GB should be quite a bit (about 250%) faster with regards to AF than the Radeon HD 3470 256MB. (explain)

GeForce GT 430 1GB 11200 Mtexels/sec
Radeon HD 3470 256MB 3200 Mtexels/sec
Difference: 8000 (250%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 3470 256MB is the winner, but it probably won't make a huge difference. (explain)

Radeon HD 3470 256MB 3200 Mpixels/sec
GeForce GT 430 1GB 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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR 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 anti-aliasing, HDR 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 worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
