EETimes profiles (http://www.eetimes.com/news/latest/showArticle.jhtml;jsessionid=UWMRJO3X2B4G%20%20WQSNDLSCKHA?articleID=196901229) a recent Intel research prototype that incorporated 80 cores onto a single CPU. As a research prototype, the CPU itself was designed primarily for experimental purposes, but Intel believes it will be able to build an 80-core Processor in the next five to eight years. This would represent a large jump over existing processors which now cap out at 4 cores per processor.

Despite the large number of cores, Intel reports that the 80-core chip required only 100 watts of energy, compared to 105-130 watts for current quad-core processors. Each of the 80 cores in the experimental processor, however, is much simpler than existing cores in today's processors, so tasks are broken down into smaller units for each core to handle. "Think more-complex four cores compared to simpler 80 cores. Each of those four cores can do more individually than one of the 80," he explains. But with an 8-core chip "you will get a lot more performance and lower power because you have a lot of them running at lower speed."Each of the 80-cores can also be recruited on demand, with active cores being shifted if one core gets too hot. This concept of "core hopping" would decrease the amount of heat generated by the processor as a whole.

Other questions addressed in this 80-core experiment was dealing with networking and communications between the 80 cores. "What we're doing is designing a network inside the chip. Today, you hear about high-performance computing and they have these big, fat super-powerful servers and they're all networked together. We're trying to basically do that, but on a chip. How do you bring a real network inside a chip so all the cores can talk to each other?" While 80-core chips may be five to eight years away, Intel's technology strategist Manny Vara suggests that some sort of hybrid processors with a combination of complex cores and simple cores could be possible in the interim.

Apple moved from PowerPC to Intel processors in June 2005 (http://www.macrumors.com/2005/06/06/macintosh-moving-to-intel-processors/), citing increased performance and reduced power consumption as the primary driving forces behind the decision.

Wow.

HAL 9000 here we come!

Didn't we hear about the 80-core chips at a previous IDF?

Don't make me get my Google-fu out...

Essentially going back to RISC cores.

We never left RISC. Intel Core architecture is RISC-based.

I thought that since they were i386 compatible, they were more CISC. They do have VLIW. (This stuff confuses me :p).

Intel scares me sometimes.

Intel's first OCD == MHz/GHz. Let's get this as fast as possible. Who cares about efficiency?

Intel's latest OCD == # of cores. Let's create a 1,000,000,000 core chip. Who cares if programs actually use them.

Sometimes I want Intel to take a step back and reflect.

true, but in the end they make some pretty awesome processors...

I guess they have some extra money to throw around and experiment.

Life is no longer simple. ;)

So, the solution used by all processors available on the market today from both Intel and AMD is to use a CISC/RISC decoder. Internally the CPU processes RISC-like instructions, but its front-end accepts only CISC x86 instructions.

looking forward to the next 5-8 years! (my wallet doesn't though)

80 cores might actually make Windows Vista responsive.

Or allow Time Machine to start a backup without brining my iMac to a dead-stop.

Better get on the Mac Pro threads and warn them not to jump the gun on Penryn, best to wait for the 1.21 gigawatt! 160-core Mac Pro!

Man.. I hate to see the size of the heat-sink if that beast,
even thought it does have 80 simplified cores... Oh i can't imagine.... Remember the G5 with it's tiny heat-sink?

i think that's "1.21 "jig"-awatts.

super - just hope the OS and apps can take advantage of them in a timely manner.
