Compatibility crossfire

Attendees wondered if they would be caught in a compatibility crossfire between Intel and AMD, asking what kind of cooperation they could hope to see between the latters AMD64 and the formers largely imitative (and less throughput-optimized) EM64T (Extended Memory 64 Technology) architecture. So far, it appears safe to say that 64-bit Windows software will run on both—because Microsoft has told Intel, in public, that AMD got there first and that Intel had better be compatible.

The incompatibilities that will exist between EM64T and AMD64, so far as eWEEK Labs can determine, will be similar to those between a Pentium III/4 and an Athlon XP.
For example, it seems likely that the rival CPU families will continue to use some different three-dimensional graphics extensions.

Other attendee questions concerning computing/TV convergence might presage a fundamental change in the PC business.

The home media server, wirelessly serving portable terminals throughout the house, starts to look both plausible and attractive when that shared device can virtualize multiple Windows or Linux sessions—while it also demodulates and delivers HDTV content via digital-wireless links to portable flat-panel displays.

What else will users do with 64-bit power? As 15 percent of the attendees replied to that poll question, "Something I wont know I want until I see it."
