GeForce GTX 470 vs Radeon HD 6950 2GB
Intro
The GeForce GTX 470 has a core clock speed of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also uses a 320-bit memory bus, and uses a 40 nm design. It is comprised of 448 SPUs, 56 TAUs, and 40 Raster Operation Units.Compare all of that to the Radeon HD 6950 2GB, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this specific model. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must 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, High Dynamic Range and high 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 texture units by the core speed of the chip. The better this number, 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 amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
