GeForce GT 430 (OEM) vs Radeon HD 3470 256MB

Intro

The GeForce GT 430 (OEM) uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this particular card. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.

Compare those specifications to the Radeon HD 3470 256MB, which uses a 55 nm design. AMD has set the core frequency at 800 MHz. The DDR2 memory works at a frequency of 950 MHz on this specific card. It features 40(8x5) SPUs as well as 4 Texture Address Units and 4 Rasterization Operator Units.

Theoretically speaking, the Radeon HD 3470 256MB should be 6% faster than the GeForce GT 430 (OEM) in general, because of its higher data rate. (explain)

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

Texel Rate

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

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

Pixel Rate

The Radeon HD 3470 256MB is a small bit (about 14%) more effective at FSAA than the GeForce GT 430 (OEM), and also able to handle higher screen resolutions more effectively. (explain)

Radeon HD 3470 256MB 3200 Mpixels/sec
GeForce GT 430 (OEM) 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 information (counted in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
