The names and model numbers of AMD's upcoming Zambezi processors might be kind of an open secret—the first leaks can be traced back to mid-March. Actual specifications are another matter, though, and the guys at DonanimHaber may be the first out there with the scoop.
According to their information, the lowest-end Zambezi processor will have four cores, a 3.6GHz base clock speed, and a 3.8GHz Turbo speed. There will also be a 3.3/3.9GHz six-core model, a 2.8/3.7GHz entry-level eight-core model, and a 3.6/4.2GHz eight-core top of the line. (The site also mentions one quad-core chip and one six-core chip whose clock speeds haven't yet been set.)
Thermal envelopes look like they'll stay largely at 95W except on the eight-core offerings, which will fit into larger 125W TDPs. Total cache sizes, meanwhile, look like they'll reflect core counts—4MB for four cores, 6MB for six, and 8MB for eight.
