GeForce GTX 460 SE vs Radeon HD 6850
Intro
The GeForce GTX 460 SE features a GPU clock speed of 650 MHz, and the 1024 MB of GDDR5 RAM runs at 850 MHz through a 256-bit bus. It also features 288 Stream Processors, 48 TAUs, and 32 ROPs.Compare those specs to the Radeon HD 6850, which makes use of a 40 nm design. AMD has set the core frequency at 775 MHz. The GDDR5 memory works at a speed of 1000 MHz on this model. It features 960 SPUs as well as 48 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
