Can anyone please update me on knowledge about laptop processors?

The 5000 lineup was skipped by most gaming laptop manufacturers as far as i can tell. The new mainstream quadcore chip is the i7-6700HQ as KHg8m3r wrote. There is also a i7-6820HK which can be overclocked. Quite a few manufacturers also put some desktop chips in their laptops. Look at the gaming lineup from e.g. asus, msi, gigabyte and clevo resellers like sager.
