"Montalvo Systems is secretly designing a new breed of energy-efficient multicore processor. The company has finished the design of a chip aimed at mobile computing. When it gets finished, it will be compatible with all the x86 software that can run on both AMD and Intel chips.
Despite the software compatibility, the chips built by Montalvo systems will be radically different from any existing chip design. For instance, its cores won't be projected symmetrically, as standard processor designs do. Montalvo's bold design will implement a bunch of highly-performing cores, mixed with lower-performing ones. This approach is extremely similar to the Cell chip produced by IBM, Toshiba, and Sony."
