GeForce GTX 460 2GB vs Radeon HD 3470 256MB
Intro
The GeForce GTX 460 2GB features a GPU clock speed of 675 MHz, and the 2048 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 32 ROPs.Compare that to the Radeon HD 3470 256MB, which has a core clock frequency of 800 MHz and a DDR2 memory speed of 950 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It features 40(8x5) SPUs, 4 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
