GeForce GT 430 (OEM) vs Radeon HD 3470 512MB

Intro

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

Compare all that to the Radeon HD 3470 512MB, which comes with GPU clock speed of 800 MHz, and 512 MB of GDDR3 memory set to run at 950 MHz through a 128-bit bus. It also is made up of 40(8x5) Stream Processors, 4 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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