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 frequency of 1080 MHz. It also features a 384-bit memory bus, and makes use of a 90 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 24 Raster Operation Units.

Compare those specifications to the GeForce GTX 460 SE, which features a GPU core clock speed of 650 MHz, and 1024 MB of GDDR5 memory running at 850 MHz through a 256-bit bus. It also is comprised of 288 Stream Processors, 48 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 processed per second. This 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
