GeForce 8800 GT 1GB vs GeForce GTS 450 1GB

Intro

The GeForce 8800 GT 1GB uses a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this card. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Compare that to the GeForce GTS 450 1GB, which has a core clock speed of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is made up of 192 SPUs, 32 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
