GeForce GT 430 (OEM) vs Radeon HD 6750 1GB

Intro

The GeForce GT 430 (OEM) comes with a GPU core clock speed of 700 MHz, and the 2048 MB of GDDR3 memory runs at 900 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 16 TAUs, and 4 Raster Operation Units.

Compare all that to the Radeon HD 6750 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular card. It features 720 SPUs as well as 36 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
