Every new iPhone needs a new engine, and Tim Cook has just made some bold claims about Apple's latest silicon creation: the A6 processor. He hinted at a significant shrinkage in transistor size, allowing the chip to be 22 percent smaller than the A5 and hence more energy-efficient, while at the same time -- he says -- doubling all-round CPU and graphics capabilities. By way of practical benefits, the Apple CEO promises the Pages app will load up 2.1x faster than before, while Keynote attachments will hit the screen 1.7x faster. At this point we're lacking any further detail about cores or clock speeds or indeed who actually fabricated the A6 (still Samsung, after all that bitterness?), but Apple does tend to be close-lipped on such things. In the meantime, bring on the benchmarks!
