Apple is undoubtedly testing ARM-based Macs internally and has been for some time. The question is, when -- or even if -- it will make the switch? A new rumor says it may be getting closer.
Developers are variously enthusiastic and skeptical about the benefits of 64-bit mobile programming, but plenty expect gains from other features in the Apple A7 chip that will arrive in flagship iPhones on Friday.
The company's move to a 64-bit chip is necessary. And it's meaningful that Apple got there first.
Apple's 64-bit A7 chip holds a lot of promise for big-screen gaming on future iPads.
Don't swallow Apple's marketing lines that 64-bit chips magically run software faster than 32-bit relics. What the A7 in the iPhone 5S does do, though, is pave the way for Apple's long-term future.
commentary Intel's power-efficient Haswell chip could enable a range of devices with the battery life of Surface RT with the power and -- more importantly -- backward compatibility of the Surface Pro.
With Apple's latest update, it appears the company has stopped issuing security updates for OS X 10.5, which means that PowerPC-based Macs will be left more vulnerable.
Xbox One uses an AMD x86 chip instead of an IBM processor, which means there's no native backwards compatibility for games.
A report says AMD chips will make it easier for game makers to port PC titles and those on mobile devices to the Xbox.
IBM is trying to advance the supercomputing state of the art in memory, optical links, and processing with research stemming from a massive radio telescope project.
