Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.

Performance of titan is not worth the price... 7970 is 25% cheaper....

Tommy says:

ups... sorry... 7970 is 75% cheaper then titan :/ OMG!

Tom says:

both same ish, but this only shows AMD last gen gpu vs NVidia new gen gpu, if u put ATI/AMD HD 7990 vs titan u will see amd wins again, AMD always win in the GPU race, AMD for my GFX and INTEL for my CPU, ati ein again, but each month both ati/amd and nvidia will out do each other so for an amount of time each will be on top

Dillon says:

Just get 2 7970s, and there's something that would pack a punch. Maybe even harder than the titan, and save 200$.. Always have been a AMD fan, and always will be. AMD FTW.

David says:

Ok, TITAN's price is worth it, having in mind that its technologies are much more advanced than those of AMD, also it has lots of power at lower power conssumption than AMD. After that, for that who said that AMD 7990 beats TITAN, of course it does, but because it has 2 processors, while TITAN just has 1 and still competes against it, blabber mouth. Anyways 7990 6GB's can't beat TITAN also because of its single CrossFire mode for up to 12GB on 2 GPUs, while TITAN beats that with ease at 24GB on Quad-SLI configuraction and can beat any GPU nowadays also due to this and much more. And a final detail, AMD just works on gaming, while nVidia works on gaming and also for more demanding design software, like Adobe and AutoDesk, due to the integration of kepler technology as on its industrial GPUs, Quadro and Tesla.

James Adkins says:

two 7970s are about $500 used on ebay right now, that is about half the price of a titan and almost 175% performance
