Nvidia has, without much publicity, four new mobile gpus released. The GTX 670MX and 675MX for the high-end, and the GT 645M for the mainstreammarkt are built around the Kepler architecture. Also there is the GT 625M.
For gaming and other laptops for the high segment had Nvidia until now only one gpu on the basis of the recent Kepler architecture. The GTX 670M and 675M are videochips that are around the older Fermi-technology have been erected. Nvidia now reports, however, in its product list with two new Kepler-variants that the GTX 670M and 675M have to follow.
The GTX 675MX is concerned with a GK104 gpu with 960 cuda cores, 4GB of gddr5 memory and a 256-bit-memory bus. The GTX 670MX is based on the GK106, which is 960 cuda cores combined with up to 3GB of gddr5 and a geheugeninterface of 192 bits. The improvements of the Kepler architecture would be much higher performance compared to the predecessors to yield.
For the mainstreamsegment has Nvidia the GT 645M was released. This laptopvideokaart is built around a GK107-Kepler-gpu, 384 cudacores, with ddr3 combined, and communicating with the memory through a 128bit wide bus. The GT 625M finally, will appear in instapnotebooks. This mobile graphics card is based on an older Fermi gpu. The chip is slightly higher clocked than the GT 620M and the performance will also be slightly higher.
