GeForce 8800 GTX vs GeForce GT 430 (OEM)

Intro

The GeForce 8800 GTX features a core clock speed of 575 MHz and a GDDR3 memory speed of 900 MHz. It also features a 384-bit bus, and uses a 90 nm design. It features 128 SPUs, 64 TAUs, and 24 Raster Operation Units.

Compare those specifications to the GeForce GT 430 (OEM), which makes use of a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this particular model. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
