64-Bit Computing: Whats in It for You

Polls of eSeminar attendees show gradual adoption for media and database tasks.

During a Ziff Davis Media Inc. eSeminar on desktop prospects for 64-bit computing March 9, attendees wondered what theyd get from the advent of Advanced Micro Devices Inc.s AMD64 or Intel Corp.s EM64T machines with their 64-bit superset of the familiar x86 platform.

Windows users at the seminar learned of Microsoft Corp.s March 3 promise of a 64-bit Windows as early as next month, exploiting the improved security of 64-bit PCs.

Microsoft has rejected the possibility that its next major update, code-named Longhorn, might be offered only in 64-bit form—but Microsoft would clearly benefit from 64-bit CPUs ability to block sections of memory from being treated as executable code.

That "no-execute" feature will pose a substantial barrier to buffer overflow attacks, which continue to dominate security loophole listings.

On the whole, attendees did not seem to resent that Microsoft might therefore nudge them in the direction of buying a new machine:

Only 3 percent expected to be, in effect, forced to do so while gaining no real benefit.

On the other hand, attendees seemed to be in no hurry to make the 64-bit move.

Fewer than 40 percent of them expected to reach a 64-bit tipping point, with most of their newly bought corporate desktop systems having 64-bit CPUs, before the end of next year—even though most of them hope to get meaningful benefits of greater capacity and speed in a broad range of applications .

Those expectations of benefits were almost evenly distributed among 32-bit performance improvements, 32-bit multisession capabilities, native 64-bit capacity for enterprise applications and native 64-bit capability for multimedia tasks.

The lead application expected to demand 64-bit resources was image and video editing, closely followed by data mining and visualization.

One-eighth of those responding to the corresponding poll put a Windows "compatibility box" at the head of their applications wish list.

This feature would let them move most applications to Linux while retaining a side-by-side Windows capability.

In the same way that 32-bit PCs built momentum by multitasking 16-bit DOS and Windows applications, so will 64-bit x86 PCs likely gain ground among power users with next-generation, multisession mojo.
