Geforce GTX 670 vs Geforce GTX 680
Intro
The Geforce GTX 670 features clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs as well as 112 TAUs and 32 ROPs.Compare those specifications to the Geforce GTX 680, which has GPU core speed of 1006 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max 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.
