Intel has just started shipping some of its fastest mobile chips to date, meaning new powerful laptops such as faster versions of Dell's Precision 5510 (above) should soon be on the market.

The new chips include Core i7 Skylake processors, as well as mobile Xeon chips that are headed for portable workstations used by those editing video and working in 3D suites such as Maya.

Intel shipped the first mobile Skylake chips last year, but they were for mainstream and entry-level laptops. These new chips, just added to Intel's price list, are aimed at the high end.

The fastest of the bunch, at 2.8GHz, is the quad-core Core i7-6970HQ, which has 8MB of cache and a list price of US$623. Other new Skylake parts include the Core i7-6870HQ and i7-6770HQ.

The chips should be Intel's fastest for laptops until it releases its next Extreme Edition gaming chip, which will also be based on Skylake. Skylake processors are manufactured using Intel's latest 14-nanometre process.

Last year, Intel launched two Xeon chips for mobile workstations. It's now adding three more. At $1,207, the quad-core E3-1575M v5, for example, runs at 3GHz and has 8MB of cache. That's Intel's second-most expensive mobile chip after the current Extreme Edition gaming parts.
