ARM adopts 64-bit architecture

This link has a bit more information. <a href="http://www.arm.com/about/newsroom/arm-discloses-technical-details-of-the-next-version-of-the-arm-architecture.php" rel="nofollow">http://www.arm.com/about/newsroom/arm-discloses-technical-de...</a><p>I wonder how these two new modes will relate to existing modes like Thumb2?

ARM is basically doing to Intel what Clayton Christensen taught Andy Grove to do with the Celeron.<p><a href="http://hbr.org/2010/07/how-will-you-measure-your-life/ar/1" rel="nofollow">http://hbr.org/2010/07/how-will-you-measure-your-life/ar/1</a>

My prediction: once this architecture is in the release channels, Intel is out of them. In a matter of years, Intel will be the dinosaur of microprocessors. Unless Intel also (re-)embraces ARM. Its simply a matter of price and configurability. ARM is simply unbeatable when it comes to price. Let alone energy efficiency. Its time to short Intel shares..

Hopefully the next iteration of the Raspberry Pi will have this!

Is there any backstory on why this is only happening now? The address space situation is already borderline in some areas of ARM usage, and cell phones are about to break 1GB of physical RAM (if some haven't already?).<p>Seems like this is a couple years overdue to have anything close to a comfortable margin.
