Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a 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 worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

4 Responses to “Geforce GTX 670 vs Geforce GTX 680”I was thinking about getting a gtx 680. But given the specifications and price performance ratio, 670 should be a better choice is money is a factor to you. 670 is more than 100 dollar cheaper than 680 and you get a performance drop only 5-6%. Search in the google for their benchmark and you will be amazed at how gtx 680 and gtx 670 go neck to neck. If overclocked, gtx 670 can easily surpass a stock gtx 680. The memory bandwitdh and vedeo ram are the same!
thanks for info in going with gtx 670
I'm getting a gtx680 for about the same price as a 670 you OC your 670 to my 680 but then i OC my 680 200mhz
I Am defiantly going to go with a GTX 680, even though more expensive, i will buy the super over clock version which is much faster with better cooling.
