GeForce 8800 Ultra vs GeForce GTX 460 SE

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 makes use of a 90 nm design. It is comprised of 128 SPUs, 64 TAUs, and 24 ROPs.

Compare that to the GeForce GTX 460 SE, which uses a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this specific card. It features 288 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 can be applied per second. This 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 video 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 amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
