From Tom's Hardware, "the APU will consist of eight x64 AMD "Jaguar" cores and a next-generation Radeon GPU comprised of 18 "compute units" capable of cranking out 1.84 teraflops. This chip will be backed by 8 GB of unified GDDR5 RAM (17 GB/sec of bandwidth), a built-in HDD, USB 3.0, a Blu-ray optical drive, Gigabit Ethernet, Wireless N and more. Note that a Radeon HD 7970 is rated at 3.5 teraflops.
AMD's "Jaguar" is the successor to "Bobcat" which powers current C- and E-Series low-power APUs. The company is expected to launch its first batch of Jaguar-based APUs during the middle of 2013, codenamed as Kabini and Temash. These 28-nm chips will have power envelopes of 15W or less, and up to four cores."
