The world's largest chip maker is set to debut an 80-core processor that will usher in the era of teraflop computing, but it's unlikely that this super-chip will ever make it to market.
Ready or not, the age of so-called "tera-scale" computing is about to start.
On Feb. 9, at the ISSCC (Integrated Solid-State Circuits Conference) in San Francisco, Intel will offer the world a glimpse at the technology behind its tera-scale computing efforts, including the design of an 80-core processor.
"Tera-scale computing is coming," said Jerry Bautista, director of Intels Tera-scale Computing Research Program. "What we are doing is bringing supercomputing-like capabilities to PCs, servers, and handheld and mobile devices."
During the ISSCC show, Intel researchers are preparing to present nine different research papers, one of which will address the details of the companys efforts to develop a processor capable of delivering teraflopstrillions of calculation per secondof performance while consuming as few as 62 watts of power.
While Intel officials were quick to say that the 80-core chip
is more a proof-of-concept design that will likely never come to market, it is possible that within 10 to 15 years certain elements and design specifications used to create this chip will be integrated with other processors.
Intel has already said that it would try to offer processors with 10 or more cores by the end of the decade. In November 2006, the Santa Clare, Calif., company began its march to offering more and more cores when it offered quad-core chips for servers and workstations that offered 1.5 times the performance of dual-core chips.

During February 2007, the company also announced that it had developed a method to achieve a 45-nanometer manufacturing process that will allow the placement of more transistors on each core to achieve greater performance, while at the same time scaling down the size of the chip.
Intel researchers predict that this type of multicore chip can find practical use in gaming, "virtual" travel and learning experiences, media management, and enterprise applications like data mining. However, several analysts remain skeptical about the lofty possibilities of multicore processing, since most software written today is not ready to take advantage of this type of multithreaded chip.
"Its tough enough to know what to do with four cores," said Roger Kay, an analyst with Endpoint Technologies.
To counter this drawback to multicore processing, Intel said it is currently working on 100 different research projects to follow up its announcement, including the development of softwareboth internally and with outside ISVsto develop applications that can take advantage of this type of processing power.

Unlike in the current crop of dual- and quad-core processors, the cores used to create the teraflop chips are much simpler, general-purpose Intel Architecture. This allows for some cores to perform highly specialized functions, such as boosting performance by running parallel jobs.
The chips will also have smaller and slower cores that will still allow top performance but will reduce the amount of power consumed by the processor.
To achieve this performance, Intel researchers designed the chips "tile" structure. This design allows these tiled cores to be replicated across the chip. In the case of the 80-core chip, 100 million transistors are stretched across 80 core tiles to achieve the design.
In the past, Intel researchers have said their findings show that eventually billions of transistors will be able to fit on a single piece of silicon. Referring to the 80-core chip, an Intel spokesperson later explained, "The researchers were bounded somewhat here by what production samples they could get out of the Fabs. For example, there was no special reason 80 was chosen: [It was] partly a measure of what was available."
