GeForce GT 430 (OEM) vs Radeon HD 4670 512MB

Intro

The GeForce GT 430 (OEM) features a core clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Compare those specifications to the Radeon HD 4670 512MB, which uses a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM works at a frequency of 1000 MHz on this model. It features 320(64x5) SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, 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 calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
