come home to viewApple ’s buy itself a chip company , P.A. Semi , that could make chips for future iPods and iPhones . The company was founded by Dan Dobberpuhl , steer architect of Alpha chips , who last yr announce a 64 - bit threefold meat central processing unit that is said to be about 300 % more efficient than the nearest competition , using only 5 to 13 watts at 2GHz .
product using the chips wo n’t arrive for a yr , at least , but we can wear that Apple would n’t spend $ 278 million without some plans to use ’em presently as it made sense , and I ’m certain Intel and ARM are n’t stoked . The negotiation , which finished late , acquire place in The Steve ’s home . have its own chip design is an interesting move . While the iPhone ’s had a lot of off the shelf componentry , it makes sense that work on its own interior hardware could yield right devices . Or a PowerPC repeat .. which is the computer architecture I consider that the above processor is built on .
More inquiry on that fleck show how it achieves such power efficiency . From Ars : “ For instance , the chip boast over 25,000 clock logic gate so that clock pulses to different region of the processor can be shut off dynamically to save great power … All of the PA6 T ’s major on - dice components have their own freestanding clock and potential drop domain , so that the L1 , L2 , DRAM restrainer , I / O subsystem , and each of the two magnetic core can all be place in different crushed - power state severally of one another . ”
Of course , the crisp in portable such as an iPhone and iPod ( as Forbes speculates ) would n’t be running so fast as the chip above . While it ’s unlikely they ’d use that dual core 64 poker chip in Macs , given the Intel permutation was so recent , it ’s my guess that P.A. Semi has a unpredicted mobile bit that Jobs lusts after . Stands to reason , although Owen at Valleywagbelieves that the want of economic scalefor Semi makes it more likely that the buy is for IP to be implemented by others , as a bargaining microprocessor chip . no matter of manoeuvre , the unnamed chip would have to be very efficient to best other offerings .
Intel ’s mobile program , Atom , by comparison , can do 0.8 watts of exercise at 800MHz , and VIA has a 0.1 watt solution thatruns at 500MHz . ARM , designer of the current iPhone poker chip , is gasconade that they can do a 0.25 watt A9 chipwith multicores at 1GHz .

Historically , P.A. Semi was stress to be the microprocessor chip provider for Macs around the prison term they take to go for Intel , and it is reported that Dobberpuhl was furious when they went x86 , thinking the Intel talks were just a bargaining chip . Some think that P.A. Semi lose its chance to be a brand name like AMD or Intel , but clearly , being under the steel name of Apple is n’t half sorry . [ Forbes , Ars , Reg , VW ]
