GeForce 8800 GTS (G92) vs GeForce GTX 560 Ti

Intro

The GeForce 8800 GTS (G92) comes with a clock frequency of 650 MHz and a GDDR3 memory speed of 970 MHz. It also features a 256-bit bus, and uses a 65 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 ROPs.

Compare that to the GeForce GTX 560 Ti, which uses a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 RAM runs at a speed of 1002 MHz on this particular model. It features 384 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
