An American site is offering Athlon 800MHz and 900MHz for sale, many months before the chips are likely to be available. That has led AMD to the conclusion that the chips must be cryogenically cooled, although the Web site is not clear on this point. They're not cheap. If you turn to Shop USA, the site is offering 800MHz and 900MHz Athlons at $2,199 and $2,799.99 respectively. An AMD representative suggested that the parts being sold were, most probably, cryogenically cooled. But the representative agreed that the page, as it stood, could potentially mislead innocent buyers. The fastest Athlon AMD currently sells runs at 700MHz, and the representative would not be drawn on future clock speeds. We are expecting a 750MHz part to become available during the week of Comdex/Fall. In fact, if Shophere USA was selling such chips without cryogenic adjustments, it would make the busy Web site a fab, which quite evidently it is not. ®
