GeForce GT 430 vs GeForce GTS 250 512MB

Intro

The GeForce GT 430 uses a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 memory runs at a speed of 900 MHz on this specific model. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.

Compare that to the GeForce GTS 250 512MB, which makes use of a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 RAM works at a frequency of 1100 MHz on this model. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range 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 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 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 number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
