Nvidia is seriously gearing up for the Intel 4th generation Core Haswell launch as it has now officially announced four new mobile GPUs that will be a part of its GTX 700M series lineup, the GTX 780M, 770M, 765M and the GTX 760M.

All four new mobile GPUs are based on 28nm Kepler architecture and while GTX 780M is the only one based on the GK104 GPU with 1536 CUDA cores. The other three GPUs will be based on the GK106 GPU with 960 and 768 CUDA cores. The shere specifications of the GTX 780M are quite impressive and, according to Nvidia, should be enough to run all the latest game titles including Tomb Raider, Battlefield 3, Far Cry 3, Bioshock Infinite and Assassins CreeD III at 1920x1080 resolution and Ultra settings.

As noted, the top-offer will be the GTX 780M based on 28nm GK104 Kepler GPU with 1536 CUDA cores. It will work at 823MHz+ GPU clock and feasture 4GB of GDDR5 memory clocked at 5GHz and paired up with a 256-bit memory interface that add up to 160GB/s of memory bandwidth. The next in line is the 28nm Kepler GK106 based GTX 770M with 960 CUDA cores, 811MHz+ GPU clock and 3GB of GDDR54 memory clocked at 4GHz and paired up with a 192-bit memory interface for 96GB/s of memory bandwidth.

The GTX 765M is also based on the 28nm GK106 Kepler GPU but features 768 CUDA cores and works at 850MHz+ GPU clock and comes with 2GB of GDDR5 memory clocked at 4GHz and paired up with a 128-bit memory interface for 64GB/s of memory bandwidth. The last but not the least is the GTX 760M based on pretty much the same specs as the GTX 765M but with a slightly lower 657MHz+ GPU clock.

All four GPUs will feature Nvidia's GPU Boost 2.0 and support Nvidia Optimus graphics switching technology that worked flawlesly with Ivy Bridge CPUs and should also work flawlesy with new Haswell GPUs. According to Nvidia, the GTX 780M is the worlds fastest notebook GPU and currently we have to agree with them. The GTX 780M is up to 31 faster than the GTX 600M series GPU that it replaces while the GTX 770M and the GTX 760M are up to 55 and 30 percent faster than its predecessors.

Nvidia also bragged about some design wins including the 14-inch MSI GE40 with Geforce GTX 760M, Asus' ROG G750 17.3-incher with GTX 780M/770M and the Acer's V3 17-incher with Geforce GTX 760M. Nvidia also claims that it will have 99%+ share on Haswell gaming notebooks and we are quite sure that we will see many of those at Computex show.
