Videocardz.com managed to get their hands on some rumored details about an upcoming NVIDIA mobile graphics card–the GTX 680M. According to rumors, the mobile chip will be launched at Computex 2012 in Taiwan next month.
There aren’t many details about the mobile chip, but it is set up to be a scaled down version of it’s Kepler based GTX 680 desktop counterpart. The GTX 680M will have approximately half as many CUDA cores at either 744 or 768 cores depending on the source. Either way, the card keeps the same 256-bit memory interface and can support SLI configurations. In addition, the 680M will be able to have up to 4GB of GDDR5 memory. Reportedly, it can use as much as 100 Watts of power.
When paired with an Intel Core i7 3720QM processor, the GPU was able to get a score of 4,905 points in 3DMark 11’s Performance present benchmark. It is supposed to be as much as 37 percent faster than the GTX 670M, which is not surprising considering that chip has only 336 CUDA cores and is clocked at 598 MHz (no word yet on what the GTX 680M will be clocked at).
No matter what the GTX 680M turns out to be, you can bet it will only be found in the highest end gaming notebooks where performance is more important than battery life. Until then, feel free to brush up on your Kepler architecture knowledge by visiting our GTX 680 (desktop) review.
