Nvidia Readies GeForce GTX 680M for High-End Laptops.

Nvidia Corp. plans to introduce its new high-end graphics solution for notebooks at Computex 2012 in Taipei, Taiwan, early next month. The new GeForce GTX 680M will be based on the GK104 graphics processing unit that belongs to the Kepler family of solutions and will be offer about one third better performance than the model GTX 670M.
According to reports from web-sites like VideoCardz and Chiphell, the GeForce GTX 680M will feature 768 stream processors and therefore 64 texture units, reduced number of raster operating units and 256-bit memory bus. It is presently believed that the GeForce GTX 680M will utilize N13E-GTX-A2 chip, which is believed to be a variation of GK104 chip. The new mobile flagship will fully support modern high-end features like DirectX 11.1, OpenGL 4.2, OpenCL 1.2, stereoscopic-3D, 4 multi-monitor capability, PhysX, 4-way multi-GPU, PCI Express 3.0 and so on.
The reports claim that the GeForce GTX 680M is 37% faster compared to GeForce GTX 670M, which is based on Fermi architecture and which has 336 stream processors operating at 1200MHz. Given the fact that the data comes without attribution to any kind of source, it should be considered as inaccurate.
Even though both Nvidia and its arch-rival AMD in the recent cycles did not use flagship GPUs in mobile computers, Nvidia did squeeze the GF100 chip into mobile thermal envelopes and introduced GeForce GTX 480M back in mid-2010.
Nvidia did not comment on the news-story.
