AnandTech has posted their final thoughts regarding Comdex Fall 2002 in their massive 18 page wrap up which covers everything in detail from AMD, nVidia and Transmeta.

It turns out that Barton will ship with a 333MHz FSB initially, and that we received directly from AMD. Remember that even at the end of 2003, shipments of Athlon XP and Athlon 64 will be an even 50/50 split - so a good deal of the market will be serviced by Barton. In an attempt to keep Barton more competitive, the 400MHz FSB would be implemented but only if chipset and motherboard designs can be reliably produced to support the spec.
