Crank said he expects mainstream demand for 64-bit desktop computing to take off with Microsofts release of Longhorn, the next version of Windows. But he added that Intel officials are not looking at the entire picture, ignoring the growing demand among the increasing numbers of high-end gamers. In an interview with eWEEK, AMD President and CEO Hector de Ruiz said he expects the client side of the industry to embrace the companys architecture, as well.The Athlon 64 and Athlon 64FX will be backed by an infrastructure of established chip set and motherboard vendors, including the first introduction of the nForce3, a chip set designed for the Athlon 64 by Nvidia Corp. Taiwan chip set vendors Silicon Integrated Systems Inc., and Via Technologies Inc. will also support the Athlon 64. The Athlon 64FX contains 105.9 million transistors, roughly twice that of the Athlon XP "Barton" core, implying that the chip will cost twice as much to manufacture. However, executives at Avnet Applied Computing, AMDs master distributor, reported that supplies of the Athlon 64 and Athlon 64FX should be sufficient to meet demand, and that the firm had already beginning shipping chips to the channel. Both the Athlon 64 and the Athlon 64 FX contain 1 MB of exclusive Level 2 cache, meaning that data written into the L1 cache will not appear in the L2 cache. The Athlon 64 uses a 64-bit memory interface to DDR400 memory, while the Athlon 64 FX includes an Opteron-like 128-bit single channel DDR interface, also to DDR400 memory modules. However, the Athlon 64FX uses registered memory of the type typically found in servers, a type of DIMM with an on-chip register that acts as a buffer, improving the reliability of data transfers. The Athlon 64FX also uses a 940-pin package, incompatible with the 754-pin socket used by the Athlon 64. Having prepared the answers to several key questions about what it is offering, AMD now must provide the answer to the most critical question of all: will anyone buy it? Analysts responses varied, although some said they feel that the Athlon XP and Athlon 64FX wont have much of an impactor at least not in enough quantities to displace the companys entrenched 32-bit Athlon XP line. While there are good reasons for customers to wait, customers wanting the fastest 32-bit processor in AMDs stable should actually choose the Athlon 64, they said. "Its not going to deliver the worlds highest volumes for the next few months," said Nathan Brookwood, an analyst with Insight 64 in Saratoga, Calif. During the fourth quarter, Brookwood said, volumes of the Athlon FX were likely to be "noise", or statistically insignificant. At the same time, AMD can exploit an opportunity. Intels next 32-bit Pentium processor, the "Prescott," may not ship in high quantities until next year, according to Peter Glaskowsky, editor of The Microprocessor Report and an analyst with In-Stat/MDR, based in San Jose. "I dont think [AMD] will meet all the demand," Glaskowsky said. "I think theyre hoping for more demand than they can fill, and maintain the highest possible price for those chips as long as possible. "There are some millions of gamers out there, and the top few percent of gamers will buy the Athlon 64 FX, especially in lieu of the Prescott," Glaskowsky said. Initially targeted for release late last year, the Athlon 64 chip launch was first delayed until the second quarter of this year, and then put off again until Tuesday. Rob Enderle, principal analyst with The Enderle Group, in San Jose, Calif., said the delays hurt AMD. Had the company been able to release its 64-bit chips last year, it would have had a significant advantage over Intels offerings. The delays enabled Intel to bolster its 32-bit Pentium offerings. The companies are hoping for big sales of Athlon 64 and Prescott chips as the holiday season arrive next quarter, Enderle said. "Both AMD and Intel are cutting it pretty close in the fourth quarter," he said. Looking forward, AMD is planning new releases of its Opteron and Athlon 64 chips in the first half of 2004. All three releases code-named Athens for the Opteron chip, San Diego for Athlon 64 and Odessa for the mobile Athlon 64 chip will be built via 90-nm process. Virtually all of the "enthusiast OEMs," including Alienware and VoodooPC, are expected to offer Athlon 64 and Athlon 64 FX machines. Northgate Innovations, a PC OEM based in City of Industry, Calif., plans to offer a $1,399 Athlon 64 based machine at retailer Costco. Discuss this in the eWEEK forum.
"The client side of the system is important," Ruiz said. "And we believe that the migration of 64-bit on the client side is going to grow faster than people think. And of course, having the infrastructure-enabled backbones in companies will allow that to happen even faster. So were very optimistic on the client side."
