GeForce GTX 470 vs Radeon HD 6950 2GB
Intro
The GeForce GTX 470 makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM works at a speed of 837 MHz on this card. It features 448 SPUs as well as 56 TAUs and 40 Rasterization Operator Units.Compare that to the Radeon HD 6950 2GB, which has a GPU core clock speed of 800 MHz, and 2048 MB of GDDR5 memory running at 1250 MHz through a 256-bit bus. It also is comprised of 1408 Stream Processors, 88 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. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
