NVIDIA is getting ready for Intel's Haswell launch by expanding its lineup of mobile GPUs with four new higher end GPUs: the GTX 780M, 770M, 765M, and 760M. They are all based on the 28 nm Kepler architecture; however, it is only the GTX 780M that will be based on the GK104 GPU with 1536 CUDA cores. The other three cards are based on the GK106 GPU with 960 and 768 CUDA cores.
The GTX 780M offers some very impressive specifications with a GPU clock of 823 MHz and 4 GB of GDDR5 clocked at 5 GHz, which combined with a 256-bit memory interface gives 160 GB/s of memory bandwidth. According to NVIDIA, all this should make the GTX 780M able to play all the latest titles, such as Tomb Raider, Far Cry 3, and Battlefield 3, at 1920x1080 resolutions with ultra settings.
The fastest of the three GK106 GPUs, the GTX 770M, sports 960 CUDA cores clocked at 811 MHz and 3 GB of GDDR5 memory with a clock set to 4 GHz paired up with a 192-bit memory interface for 96GB/s of memory bandwidth. The GTX 765M and 760M both have 768 CUDA cores, plus 2 GB of GDDR5 memory clocked at 4 GHz on a 128-bit memory interface, giving it 64 GB/s of memory bandwidth. What sets them apart is the core clock. The GTX 765 has a core clock of 850 MHz, whereas the GTX 760 has a core clock of 657 MHz.
All the GPUs will feature NVIDIA's GPU Boost 2.0 technology and support NVIDIA Optimus graphics switching technology, which helps prolong the battery life when the dedicated GPU isn't needed.
