Intel researchers have created an experimental many-core processor with 48 cores. The so-called single-chip cloud computer (SCC) features 24 dual-core tiles with 384KB L2 cache per core and is made on a 45nm HKMG process
The SCC chip features four integrated DDR3 memory controllers, there's one memory controller per six tiles and they can address up to 64GB DDR3 memory. The two cores on each tile communicate through a message buffer, and routers allow each tile to share data with other tiles. Also interesting is the power-efficient design, each tile can run at a different frequency and there are six banks of four tiles that can run at different voltages.
The 48-core chip features a total of 1.3 billion transistors and measures 567 square millimeters, power consumption is said to be between 25W and 125W. Intel said about 100 or more of these experimental chips will be made for research facilities, with the goal of developing new software and programming models for the many-core future.
