GeForce GTX 460 SE vs GeForce GTX 470

Intro

The GeForce GTX 460 SE comes with core clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 288 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.

Compare that to the GeForce GTX 470, which comes with a core clock speed of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also uses a 320-bit memory bus, and uses a 40 nm design. It features 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
