On-chip water-cooling by IBM

[Linktothepast]

Have anyone seen the on-chip water-cooling solution by IBM for their new processors that clock up to 5ghz? Hope it will become an industry standard or something . Here is the video btw. Hot water for everyone .

Wow, that's awesome. I doubt we'll ever see something like that for home use in the next decade though. Unless Intel and AMD design their CPUs for watercooling specifically...

[cottonvibes]

i've thought about the idea it says towards the end, "using the hot water from the chips to take a bath, or in a swimming pool."

that idea will never work. it would require you to integrate your PC with you house's plumbing. which is rediculous... who is going to mod their house just for their PC?


also that video says that its the first time a chip has run past 5Ghz. OCers have gotten even P4 chips past 5Ghz years ago...

anyways, that is a cool idea. maybe in 2 years we'll start seeing it being integrated with user-CPUs.

[skoreanime]

Yes, but stable 5GHz ? I think that's what they were implying. Plus, those are multi cores obviously, so that's even more impressive.

Integrating the heat pipes to your hot water boiler shouldn't be too hard of a concept. It's feasible, but to completely depend on the heat source on the heat pipes from the CPUs?...I dunno about that part.

i think now theres some stable 5Ghz multi-core OCs out.

and yes the water thing is feasible, but i was saying its too much of a pain for what its worth. and nobody is going to take the time to do it.
and its not to "completely depend" on the CPU's heat; i think its just as an addition to your water boiler.

Officially by it's company i think they are the first, they don't lie about that (overclocking is a completely another story, where the user takes the responsibility for any damage). And while for a single pc in a house might sound ridiculous, in a big company with many computers is not that bad as an idea actually (especially servers ).

i've seen articles about chips at 500 Ghz in the lab.
they just had to be run on liquid nitrogen...
this was like 2 years ago.


you have a point about the second thing you mentioned. But its still true that the building's plumbing would have to be modified, and i'm not sure how much people would do something like that.
plus, who would you call to install something like that?
a plumber or a computer technician?

i would say youre not examining the problem closely enough. i think the logic behind them providing uses for the hot water is only an extension of considering that the hot water has to go somewhere.

i know thats not the main issue; i'm just saying i've thought of it b4, and its not a good idea... or rather its not a "practical" idea.
i think its kindoff dumb that they even put that idea in the video, considering how un-practical it is.

plus, its not like you need one of those chips to do that. theres already water-cooling kits... if outputing the hot-water into your water boiler was a good idea, people would have done it with their water cooled PCs by now.

well big corperations use refrigeration units (phase change) to cool there computer systems.....IBM may be trying to make some headway into the home user market

That's interesting, But with conjunction with this one I think it's gonna be awesome.. (rather old news tho, )

IBM Initiative for Light-Based Chip Cores Interconnection

- Why use conductive materials when light would do just great?

IBM has developed a technology that, if proven successful, would bring the world one step closer to the most unbelievable SF predictions. If electric current was a breakthrough, how would you consider substituting
it with... light? The new technology is alleged to allow different CPU cores exchange signals through light pulses, instead of using electrons. The method is supposed to be faster and more efficient and would heavily reflect in the chip's performance.

The new technology uses a silicon electro-optic modulator, called the Mach-Zehnder electro-optic modulator, that converts electrical signals into pulses of light. The IBM research team has successfully achieved a 1,000 to 1 miniature version of the device and has created complete optical routing networks to be integrated onto a single chip. Electric current suppression would eventually result in faster, cheaper and cooler chips to feature a hundred times faster communications bandwidth than the wired equivalents.

"Work is underway within IBM and in the industry to pack many more computing cores on a single chip, but today’s on-chip communications technology would overheat and be far too slow to handle that increase in workload," said Dr. T.C. Chen, vice president, Science and Technology, IBM Research. "What we have done is a significant step toward building a vastly smaller and more power-efficient way to connect those cores, in a way that nobody has done before."

World's most advanced processor is not used on personal computers, as many may think, but is to be found inside Sony's Playstation 3 and features 9 cores on a single chip. At the moment, multiple core integration is handicapped by the fact that wired interconnectivity takes space and radiates heat at the same time. Eliminating the wires would allow hundreds or thousands of cores to be interconnected in a single chip. More than that, sending information between cores can be 100 times faster and 10 times more energy-efficient.

The only problem with the optoelectronic devices is making them small enough to be ready for chip integration, as they have proven tricky to manufacture over the time. The only viable solution would be mass-manufacturing using the silicon manufacturing lines capabilities for components that measure only a few millimeters on a side. There is no estimated time for the products to be actually used in multiple-core chips, but the idea itself is enough to keep things moving towards the right direction.

i was thinking about making something like that a few years ago....my teacher said im crazy. and cricghton covers that too. Read congo....the book.....not the movie

[cottonvibes]

rebel posted what i was talking to you about in that other thread phil
that new technology is going to increase chip speeds by a ton.

so maybe that the way we'll end up having PS3 emulation.

you're talking about vastly different quantities of water.
