GeForce 8800 GTS (G92) vs GeForce GTX 550 Ti

Intro

The GeForce 8800 GTS (G92) makes use of a 65 nm design. nVidia has set the core speed at 650 MHz. The GDDR3 memory works at a speed of 970 MHz on this particular card. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.

Compare those specifications to the GeForce GTX 550 Ti, which makes use of a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 memory is set to run at a frequency of 1026 MHz on this particular model. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
