Intel Showcases 80-core Processor
Intel researchers have developed the world?s first programmable processor that delivers supercomputer-like performance from a single, 80-core chip not much larger than the size of a finger nail.
This is the result of the company's "Tera-scale computing" research
aimed at delivering Teraflops -- or trillions of calculations per
second --performance for future PCs and servers. Technical details
of the Teraflops research chip will be presented at the annual
Integrated Solid State Circuits Conference (ISSCC) this week in San
Francisco.
Tera-scale performance, and the ability to move terabytes of data, will play a pivotal role in future computers with ubiquitous access to the Internet by powering new applications for education and collaboration, as well as enabling the rise of high-definition entertainment on PCs, servers and handheld devices.
Intel has no plans to bring this exact chip designed with floating point cores to market. However, the company?s Tera-scale research is investigating new innovations in individual or specialized processor or core functions, the types of chip-to-chip and chip-to-computer interconnects required to best move data and, most importantly, how software will need to be designed to best leverage multiple processor cores. This Teraflops research chip offered specific insights in new silicon design methodologies, high-bandwidth interconnects and energy management approaches.
The first time Teraflops performance was achieved was in 1996, on the ASCI Red Supercomputer built by Intel for the Sandia National Laboratory. That computer took up more than 2,000 square feet, was powered by nearly 10,000 Pentium Pro processors, and consumed over 500 kilowatts of electricity. Intel?s research chip achieves this same performance on a multi-core chip.
According to Intel, this 80-core research chip achieves a teraflops of performance while consuming only 62 watts - less than many single-core processors today.
Intel used 100 million transistors on the chip, which measures 275 millimeters squared. By comparison, its Core 2 Duo chip uses 291 million transistors and measures 143 millimeters squared. The chip was built using Intel's 65-nanometer manufacturing technology.
The chip features an innovative tile design in which smaller cores are replicated as "tiles," making it easier to design a chip with many cores. With Intel?s discovery of new and robust materials to build future transistors and no immediate end in sight for Moore's Law, this lays a path to manufacture multi-core processors with billions of transistors more efficiently in the future.
The Teraflops chip also features a mesh-like "network-on-a-chip" architecture that allows super-high bandwidth communications between the cores and is capable of moving Terabits of data per second inside the chip. The research also investigated methods to power cores on and off independently, so only the ones needed to complete a task are used, thus providing more energy efficiency.
Further Tera-scale research will focus on the addition of 3-D stacked memory to the chip as well as developing more sophisticated research prototypes with many general-purpose Intel Architecture-based cores.
Intel is presenting eight other papers at ISSCC, including one which will cover the Intel Core micro-architecture and its use in dual and quad core processors spanning laptops to desktop PCs and servers, using both 65nm and 45nm process technologies. Other papers cover such topics as a Radio Frequency Identification (RFID) reader transceiver chip, a low-power cache for mobile applications and a reconfigurable Viterbi accelerator in addition to novel circuits for on-die supply resonance suppression, on-chip phase-noise measurement and adaptive techniques for variations and aging.
