AMD is likely to ship Athlon 64 processors in small quantities before the scheduled September release, could be as early as August according to Digitimes

However, sources at first-tier motherboard companies such as Asustek Computer and Gigabyte Technology confirmed that AMD disclosed that it will begin supplying two desktop-use Athlon 64 processors, the 3100+ and 3400+, in August. However, given that shipments will reach only a projected 200,000-300,000 units by year-end, board makers expect little impact on Pentium 4-platform products in the short run.[/COLOR]
