GeForce GTX 460 1GB vs Radeon HD 6970
Intro
The GeForce GTX 460 1GB features a GPU core clock speed of 675 MHz, and the 1024 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 TAUs, and 32 ROPs.Compare those specifications to the Radeon HD 6970, which features a core clock speed of 880 MHz and a GDDR5 memory speed of 1375 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is made up of 1536 SPUs, 96 Texture Address Units, and 32 ROPs.

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