Compaq was today caught advertising Athlon 750MHz PCs ahead of AMD's launch date. The US vendor was advertising two desktops in its Presario range on its US site with the 750MHz chip, which it is understood will be officially launched by the chipmaker on Monday. The Presario 5900Z-750, based on the 750MHz chip, is priced at $2,549. It comes with 128MB DRAM, 27GB hard drive and 17 inch monitor, according to Compaq's US site. The second machine based on the processor is the Presario 5900Z-750, priced at $2,770. It comes with 128MB DRAM, 34GB hard drive and 17 inch monitor. According to one reader, the advert had been on the Compaq Web site since yesterday. When contacted, AMD was reluctant to comment on Compaq trying to steal its thunder. "I wasn't aware of it [the advert]," an AMD representative said. "I'll have to check it out for myself. She refused to comment on the 750MHz launch or what AMD's reaction was to vendors which advertised chips before the official launch date. Compaq in the US was unavailable for comment because of the Thanksgiving weekend. It seems that Big Q thought it could secretly slip the advert on the site over the holiday period to be ready for all those sales on Monday morning. ® See also: AMD confirms 750 Athlon a go-go, mentions Register in despatches AMD piles on Intel pressure with 750MHz Athlon Mobos for 750MHz .18 micron Athlons easy peasy
