GeForce 8800 GTS (G92) vs GeForce 9800 GTX+
Intro
The GeForce 8800 GTS (G92) features core clock speeds of 650 MHz on the GPU, and 970 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.Compare all that to the GeForce 9800 GTX+, which makes use of a 55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 RAM runs at a speed of 1100 MHz on this particular card. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
