Haswell is hardly a secret at this point: there's been a steady drip-drip of demos and technical leaks since as far back as 2011, and just a month ago we brought you the low-down on its integrated graphics. But today, finally, we have official pricing for a number of variants, a concrete date for availability (this coming Tuesday, June 4th) and, perhaps most importantly, some detailed benchmark claims about what Haswell is capable of -- particularly in its mobile form.

Sure, Intel already dominates in MacBooks, Ultrabooks (by definition) and in hybrids like Surface Pro, but the chip maker readily admits that the processors in those portable PCs were just cut-down desktop chips. Haswell is different, having been built from the ground up with Intel's North Cape prototype and other mobile form factors in mind. As a loose-lipped executive recently let slip, we can look forward to a 50 percent increase in battery life in the coming wave of devices, with no loss of performance. Read on and we'll discover how this is possible and what it could mean for the dream of all-day mobile computing.
