Haswell preview suggests similar gains to Ivy Bridge over Sandy Bridge

A detailed performance test of a prototype Core i7 Haswell chip by tom’s Hardware suggests that it will offer a 7 percent to 13 percent performance gain over equivalent Ivy Bridge CPUs—a similar gain to that experienced with the move from Sandy Bridge to Ivy Bridge.

The integrated HD 4600 GPU experiences an impressive speed boost of almost 30 percent, but the website noted that this still won’t allow for comfortable gaming on HD monitors, so gamers will need discrete graphics chips.

While performance gains reached up to 75 percent in the case of some specific tasks, the gains for typical desktop applications are relatively modest.

Modbook Pro: Pen-based OS X tablet returns as a converted 13-inch MacBook Pro running Mountain Lion

Almost three years before Apple launched the original iPad in 2010, a company by the name of Axiotron unveiled the first “Mac tablet” with the launch of the Modbook—a stylus-based tablet running OS X that is made from a converted MacBook Pro. Today, the Modbook is officially returning thanks to one of its original developers and designers. Former co-founder of the now-defunct Axiotron, Andreas Haas, and his new company LA-based Modbook Inc., today announced the new Modbook Pro- “the world’s most powerful and largest-screen tablet computer.”

Like past generations of the Modbook, the Modbook Pro uses the guts of one of Apple’s new MacBook Pros. The company will offer two configurations, both with a 13.3-inch, 1,280-by-800 flush-mounted display, based off the specs for the recently refreshed non-Retina MBPs running Mountain Lion:

The Modbook Pro’s configurable base system includes a 2.5GHz dual core Intel® Core™ i5 processor or 2.9GHz dual core Intel Core i7 processor, up to 16GB of RAM, a 2.5–inch SATA drive (up to 1TB HDD or up to 960GB SSD), an 8X SuperDrive® DVD burner, an Intel HD Graphics 4000 chipset, 802.11n Wi-Fi and Bluetooth 4.0 wireless connectivity capability

The company is promising seven hours on a full charge from a built-in 63.5-watt-hour lithium-polymer battery (Modbook will also utilize a 60W MagSafe adapter). As for the digitizer and included stylus, Modbook will once again use Wacom tech:
