Intel Core i7-4700HQ and Nvidia GeForce GTX 770M
The hardware inside the ASUS G750JX is impressive, especially the processor. It's a BGA Intel Core i7-4700HQ that's soldered to the motherboard. The lack of a processor socket saved some vertical space.
The GeForce GTX 770M is a Kepler GK106 processor with 960 active CUDA cores running at 705 MHz. It's less powerful than the GTX 780M which has 1536 CUDA cores, or shader units. The card has a 192 bit memory bus along with 1.5 GB GDDR5 of video memory. In notebook terms this is pretty powerful graphics card, which you'll see in the benchmarks.
