Chekib Akrout, senior vice president of AMD's technology group, offered details on the hardware of the APUs. Both Zacate and Ontario are part of AMD's low-power Brazos platform, which focuses on notebooks, netbooks and other small mobile devices. The two APUs are built on AMD's 40 nm architecture codenamed Bobcat, which features a sub-1 W x86 CPU core. As improved versions of Bobcat arrive in the coming years, AMD will reduce the size of the die from 40nm to 28 nm, Akrout said.
In addition to the Fusion APUs, Meyer also said he was "excited about the technology portfolio underlying our product roadmap" and mentioned another forthcoming CPU -- codenamed Bulldozer -- that's scheduled to ship in 2011.
AMD's Bulldozer is a multi-threaded, high-performance x86 CPU and includes a 32nm desktop version, codenamed Zambezi (4, 6 or 8 core versions), and two 32nm server editions codenamed Valencia (6 or 8 cores) and Interlagos (8, 12 or 16 cores). Akrout said the Bulldozer architecture includes two integer units, along with one floating-point unit, and two threads on separate integer units rather than a single-core solution.
AMD executives did not spend much time discussing the performance of the new Fusion chips. "The market doesn't care about head-to-head performance," said General Manager Rick Bergman. "It cares about who can offer the best experience."
