The T-bird rides at THG
Whoa! Tom jumped the gun, broke the NDA, and published his review of the AMD Athlon Thunderbird. It's only in German right now, so the link above uses a translator for your assistance and bemusement.
Based on the THG (Teutonic Hormone Giant) tests, the T-bird looks strong, but a little disappointing, losing some of the tests at 1GHz to the Pentium III. Still, the T-bird is extremely fast, and with luck, they'll be cheaper and more widely available than the GHz PIIIs.
More on this story as the NDAs expire, or as other sites elect to follow THG and bust the NDA. And thanks to the AMD Zone for the link.
