GeForce GTX 460 (OEM) vs GeForce GTX 480

Intro

The GeForce GTX 460 (OEM) uses a 40 nm design. nVidia has set the core frequency at 650 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this particular model. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

Compare all that to the GeForce GTX 480, which makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR5 memory is set to run at a speed of 924 MHz on this card. It features 480 SPUs as well as 60 TAUs and 48 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
