GeForce 8800 GT 512MB vs GeForce GTX 650 Ti

Intro

The GeForce 8800 GT 512MB comes with a core clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit bus, and uses a 65 nm design. It is made up of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.

Compare all that to the GeForce GTX 650 Ti, which has a clock frequency of 928 MHz and a GDDR5 memory frequency of 1350 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 768 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
