GeForce 8400 GS 512MB vs GeForce GTS 450 1GB

Intro

The GeForce 8400 GS 512MB features a GPU core speed of 650 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 64-bit bus. It also is comprised of 16 SPUs, 8 TAUs, and 4 Raster Operation Units.

Compare those specs to the GeForce GTS 450 1GB, which comes with a GPU core clock speed of 783 MHz, and 1024 MB of GDDR5 RAM running at 902 MHz through a 128-bit bus. It also is made up of 192 Stream Processors, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
