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

Intro

The GeForce GT 430 (OEM) comes with core clock speeds of 700 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR3 memory. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Compare that to the Radeon HD 4670 512MB, which has GPU clock speed of 750 MHz, and 512 MB of GDDR4/GDDR3/DDR3/DDR2 memory running at 1000 MHz through a 128-bit bus. It also features 320(64x5) Stream Processors, 32 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out 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 video card will be at 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 card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
