64-Bit Takes Off

64-bit desktop computing has taken a significant step toward becoming a pervasive reality:AMD's ( Advanced Micro Devices ) release of its Athlon 64 chips — and Apple 's launch of its G5 CPUs — means 64-bit processors, once reserved for servers and high-end workstations, are now in PCs available on retail shelves.

In time, 64 -bit PCs could change the face of desktop computing. A 64 -bit chip can run longer, more complex instructions than a 32 -bit one, improving performance of dataintensive tasks such as audio and video encoding, advanced engineering design apps1 ,and, naturally, games.

Equally key is a 64-bit CPU's ability to recognize and use a lot more RAM2 . Today's 32 -bit chips, such as AMD's Athlon XP and Intel's Pentium 4 , can address up to 4GB of RAM split between the OS and applications. Few PCs have that much memory, and even fewer apps use it. But with ever-more-complex software, that limitation may become a bottleneck, making Athlon 64's ability to address a whopping terabyte ( 1000GB) 3 of physical memory very attractive.

Why is AMD pushing the 64 -bit angle at all? Because company executives believe the 64 -bit desktop age is dawning now."Once video editors watch a 64-bit PC encode video directly to a DVD on the fly, they'll want one , "says Rich Heye , vice president of AMD's microprocessor unit. And once gamers see the cinematic quality that 64-bit chips help make possible , they'll want one. Though mass-market adoption will take a few years, " the average lifetime of a PC is three to four years, and I think a lot of people will be running 64 bits before that's up, "Heye says.

Executives at Intel disagree, seeing 64-bit computing as largely a server technology in the short term."With just 5 percent of servers using 64-bit addressability, there is little need today [ for 64 bits] on the desktop, "says George Alfs, Intel spokesperson, adding that with out software and other tools to make it work at its best, 64 bits doesn't mean much.

MicroDesign Resources's Krewell sees Intel's resistance to 64 bits for the desktop as a move to protect its sizeable investment in its 64-bit Itanium CPU, designed for servers and workstations.

Meanwhile, with Athlon 64 , AMD has reignited the chip wars."That's always good news for users, "says MDR's Krewell.
