GeForce GTX 460 1GB vs Radeon HD 6850
Intro
The GeForce GTX 460 1GB has a GPU core clock speed of 675 MHz, and the 1024 MB of GDDR5 RAM runs at 900 MHz through a 256-bit bus. It also features 336 Stream Processors, 56 TAUs, and 32 Raster Operation Units.Compare those specs to the Radeon HD 6850, which uses a 40 nm design. AMD has set the core speed at 775 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this particular card. It features 960 SPUs along with 48 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
