But there's a post on the Ace's Hardware forum which seems to suggest it's all a fake.
That thread starts here, and points out there are other products which haven't yet seen anything like the light of day...
The link at SI leads to a Montreal base site which has a number of processors listed and which says that you can pre-order Athlon64s.
The speeds listed are 2GHz (3400+), a 3600+ and a 3800+.
These latter too have the PR numbers attached but no frequency speed against them.
Further down in this document -- fake or no fake, it says that the Sledgehammers are also available for pre-order, and there are motherboards like the Tyan Thunder K8X Pro and the Asus ABAXX and ABVXX listed.
You can find the Silicon Investor posting here, and the PDF catalogue right here. ยต
