GeForce GT 430 1GB vs Radeon HD 3470 512MB

Intro

The GeForce GT 430 1GB uses a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular card. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.

Compare those specifications to the Radeon HD 3470 512MB, which features core speeds of 800 MHz on the GPU, and 950 MHz on the 512 MB of GDDR3 RAM. It features 40(8x5) SPUs along with 4 TAUs and 4 Rasterization Operator Units.

GeForce GT 430 1GB 28800 MB/sec
Difference: 1600 (6%)

Texel Rate

The GeForce GT 430 1GB is a lot (approximately 250%) better at texture filtering than the Radeon HD 3470 512MB. (explain)

GeForce GT 430 1GB 11200 Mtexels/sec
Radeon HD 3470 512MB 3200 Mtexels/sec
Difference: 8000 (250%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 3470 512MB is a better choice, though only just barely. (explain)

Radeon HD 3470 512MB 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: Bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 ability to get to the maximum fill rate.
