Intel has begun selling programming tools that let developers create software that supports 64-bit x86 chips, an important step in making the new generation of processors useful.

The proposed x86S CPU architecture from Intel would ditch support for 32-bit apps and operating systems entirely in favor of 64-bit software, but it could support older apps with virtualization.

Intel's 64-bit Itanium architecture deviated from the x86 architecture, although emulation provided support for x86 processors. Very large caches put the Itanium beyond reach for many users.

In a move that has a significant part of the internet flashing back to the innocent days of 2001 when Intel launched its Itanium architecture as a replacement for the then 32-bit only x86 architect… ...

Although the 64-bit x86 architectures from AMD and Intel are almost identical, in some cases programs written for one chipset may not run properly on the other, according to a report issued Monday by ...

Intel’s Itanium CPUs, once a play for 64-bit servers and desktops, are dead Final “Kittson” processors are drop-in replacements for older chips.

They let developers create software that supports 64-bit x86 chips--important in making the new generation of chips useful.

As I understand it, you can still run 32-bit applications on the proposed 64-bit only processors. But that would have to happen under some sort of virtualization, i.e. a 64-bit OS providing a ...
