GeForce GT 430 vs Radeon HD 3470 256MB

Intro

The GeForce GT 430 uses a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 memory works at a frequency of 900 MHz on this card. It features 96 SPUs along with 16 TAUs and 4 Rasterization Operator Units.

Compare those specs to the Radeon HD 3470 256MB, which makes use of a 55 nm design. AMD has clocked the core speed at 800 MHz. The DDR2 RAM works at a speed of 950 MHz on this specific model. It features 40(8x5) SPUs as well as 4 TAUs and 4 Rasterization Operator Units.

The GeForce GT 430 will be much (more or less 250%) more effective at AF 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 will be just a bit (approximately 14%) faster with regards to full screen anti-aliasing than the GeForce GT 430, and also will be capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
