LOW-POWER, 80-CORE PROCESSOR LANDS ON TERA FIRMA

LIKE DEATH AND TAXES, the demand for greater computing power is inevitable. So to meet that hunger for processing power, Intel has developed the first programmable processor with 80 floating-point cores (see Figure). Essentially a supercomputer on a chip, the device promises performance in the trillions of calculations per second, a.k.a., Teraflops. Equally impressive is the fact that the processor chip measures a bit larger than the tip of a human finger and consumes a puny 62W of power, a bit less than the majority of single-core processors currently in use.

Back in 1996, Intel first demonstrated Teraflop performance with the A supercomputer on a chip, ASCI Red Supercomputer, built for Sandia National Laboratory. Larger Intel's research processor than 2,000 square feet, ASCI Red employed close to 10,000 Pentium integrates 80 floating-point cores, Pro processors and consumed beyond 500 k W of power. measures a bit larger than a The 80-core processor utilizes a tile design whereby smaller cores are fingernail, and consumes just replicated as "tiles." This approach makes the integration of numerous 62W of power. cores less complex, leading to a significantly more efficient approach to manufacturing multi-core processors in the future.

Paired with this wafer design is a mesh-like, network-on-chip architecture, which moves Terabits of data per second within the processor. Power efficiency is the result of discovering various methods for powering the cores on and off independently. This ensures that only those cores required for a particular task are on.

The device, which is still in the design stage, is the brainchild of the company's Tera-scale computing research team. With no stated intention to deliver this particular chip to market, it is said to be the springboard to ongoing research into unique processor or core functions, as well as special interconnects between chips to move data at the higher speeds. According to Intel's Chief Technology Officer Justin Rattner, ""It points the way to when Teraflop designs will be commonplace and reshape what we can expect from computers and the Internet."
