GeForce 8800 Ultra vs GeForce GTX 460 (OEM)

Intro

The GeForce 8800 Ultra comes with a core clock speed of 612 MHz and a GDDR3 memory speed of 1080 MHz. It also makes use of a 384-bit bus, and uses a 90 nm design. It is made up of 128 SPUs, 64 TAUs, and 24 Raster Operation Units.

Compare those specifications to the GeForce GTX 460 (OEM), which uses a 40 nm design. nVidia has set the core speed at 650 MHz. The GDDR5 RAM runs at a speed of 850 MHz on this card. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. 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 is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
