    So Apple, when can I place my order for a Dual 80-core set up? :D

    So I guess this means I should by the 8-core Mac Pro this year.... and in 5 years or so when it's no longer the mighty machine it once was, I can upgrade and get 10x the number of processors! :eek:

    Let's just hope all apps will be multi-threaded by then!

    What is astounding, is how in the space of 11 years, technology has allowed 2,000 square feet and 10,000 processors to fit on a single chip and on 80 cores... Phew!:eek:

    Why wait for Santa Rosa when you can wait for this...

    Intel readies the next generation of PC chips

    Hmm, 80 cores? Imagine what a Mac Pro would be like with two of these baby's in it?? I hope you have a dilithium chamber or a naquada generator on hand for the power required, not no mention one hec of an A/C unit to keep it cool.

    The chip is air cooled and only consumes 62 watts at teraflop speeds. That's less than a current Mac Pro dual xeon. No need for the fancy solution you're suggesting.

    how long, by estimation with respect to historical data, will we be seeing the said chip commercially?

    I know that is truly amazing to think that you could shrink 2,000 square feet into a matter of inches. :)

    ah so I see a trend here. Now that we've reached a certain limit in speeds, we are now focusing on cores. Imagine, basing a computers speed on the amount of cores it has. One mac offers 100 cores while another has 220, with a 500 dollar price difference. Ver yexciting times indeed.

    I would not rule out more increases in clock speed, but the emphasis does seem to have shifted to the amount of cores that a processor contains. :)

    The chip will never see the light of day, the technologies within the chip, however, will.

    These are not x86 cores, so they would be pretty useless for general computing.

    However, it will be great at specialized tasks.

    The people in here commenting on 80 core being used in general consumer comps are full of it. Intel specifically said this is only for their own internal and other highly demanding scientific operations. Moreover, they will not be doing anything over 32 as any positive becomes significantly outweighed by the negatives. Try reading over something once and a while before just blathering words.

    Well, I'd say you might want to lighten up a little bit.

    Seems like some people took the time to read, contemplate, and if necessary, correct the misconceptions of other posters in a polite, even dignified manner.

    As far as I understand Intel will take this design and implement 8 or 16 x86 capable cores in one package based on this Tera-Scale project.

    That would be the way to go, otherwise they would need far more than 80 cores on a single package.

    Interesting how they've not mentioned how long the chip lasts isn't it? My guess is that no more than a few minutes.

    We'll see something like that, but 80 is a weird number in the world of base2 math. I'd guess we'll see the standard progression of 2, 4, 8, 16, 32, 64, etc.

    ... and not for many a year...

    -Ah HA!

    I knew there to be a rub.

    This explains how there were even able to get it to work

    "The cores in this particular CPU are not full CPU cores with full x86 instruction sets, but more focused on floating point calculations."

    If they were, I'd be worried how they got past the 4-core memory caching barrier.

    For those that don't understand...

    This was created solely as an engineering exercise to deal with the feasibility of putting so many cores on one die. It is not a commercial product for any use whatsoever, and will not become one.

    What this is more similar to than an '80 core processor' is really an '80 node network'. Instead of a conventional 'front side bus' link between the cores, about 1/4 of each 'core' is really a small networking switch. It links to its own core, to the (up to) four surrounding cores, and one going 'out' for connection to future stacked cores.

    The big advantage over conventional multi-core systems is that on a conventional system, every circuit in the chip has to be designed to receive the clock signal simultaneously. The more transistors on the chip, the more you have to worry about clock propagation. On this design, you only need to worry about clock propagation within each core. That is the big advancement on this design, is the ability to have many many cores that don't need to worry about the clock signal. (Their estimate is that in current processors, up to 30% of the power is used solely to worry about the clock signal, in this new design, it's more like 5%.) This makes for a performance hit, but for such a massive energy savings, it's worth it. (Since now you can almost double the number of cores for the same power!)

    This is also going to be more useful when we get to different cores on the same die. For example, you could separate out the integer unit from the floating point unit, from the vector unit, and have much simpler individual cores that are capable of faster individual performance on their tasks than a simple multi-big-core unit would. This means that we could see, say, 4 integer cores, 8 floating point cores, and 20 vector cores, for a monster 3D processor.

    This was co-developed with their 'stacked dice' concept, where instead of having one huge die that contains everything, you just stack individual dice on top of each other. So you'd have your 32-core processor on one layer, and your cache on a second layer, maybe a similarly-designed GPU on a third layer, etc. Higher-end processors would have more stuff on more layers. Want double the cache? No need to completely redesign the processor, just add another cache layer! This makes manufacturing cheaper, because each layer could be made and tested separately. And if you over-fill each layer, you can even deal with individual cores being bad. (So on my 32-core example, you would have maybe 40 cores total, so that any 8 could be bad and you'd still have a fully functional 32-core processor.)

    Basically, this is a complete shift in the design of processors, away from the 'processor connected to the northbridge' concept and toward a 'processors are a network of their own' concept. Just as originally, all components resided on the processor's bus, then we moved to a separate processor bus, now we're on INTERNAL busses.

    These are pretty much number crunching cores.

    One thing I haven't seen mentioned is that Intel is looking to get into the Graphics business. A 1.2 teraflop graphics card could pretty much do real time ray tracing and some other pretty cool stuff. At 62 Watts, it would eliminate the need to move to external graphics card enclosures like ATI and nVidia are proposing. This was built with 65nm process, I wonder what the new 45nm and the new gate technology could do for something like this? Looks like Gaming has a bright future.

    I'm sure the scientific community just wet themselves thinking of all the possibilities. A low cost supercomputer that takes a couple of orders of magnitude less power to operate.

    As long as it runs Atari 2600 Asteroids or Intellivision Astrosmash - I'm happy.

    well by the time a mac pro comes out with this many cores, i'll be ready to upgrade :)
