GeForce GT 430 (OEM) vs GeForce GTS 250 512MB

Intro

The GeForce GT 430 (OEM) features a GPU clock speed of 700 MHz, and the 2048 MB of GDDR3 RAM is set to run at 900 MHz through a 128-bit bus. It also is made up of 96 SPUs, 16 TAUs, and 4 ROPs.

Compare those specs to the GeForce GTS 250 512MB, which features a core clock speed of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit memory bus, and uses a 65/55 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 reach the max fill rate.
