IBM Power 575 performs at 600 GFlops per node

Computer enthusiasts that overclock their CPUs have known for a long time that liquid cooling has the potential to cool the processor better than air cooling. Liquid cooling in the enthusiast space is common and has even given way in the extreme performance categories to much more exotic means of cooling processors.

In the supercomputer realm companies like IBM have traditionally relied on air cooling for the CPUs via air conditioning for the room the supercomputer is in. IBM introduced its latest supercomputer called the Power 575, which is equipped with IBM’s latest Power6 microprocessor. The Power 575 has moved from air cooling to liquid cooling and thanks to the liquid cooling useing water-chilled copper plates located above each processor, the new supercomputer requires 80% fewer air conditioning units.

The significantly reduced need for air conditioning means that the energy needed to cool the data center can be reduced by 40%. IBM researchers say water can be up to 4,000 times more efficient than air cooling for computer systems.

The Power 575 supercomputer has 448 cores per rack and provides over five times the performance of its predecessor and is three times more energy efficient per rack. Each rack features 14 2U nodes each consisting of 32 4.7GHz cores of Power6 and 3.5TB of memory. Each node is capable of 600 GFlops and is three times more efficient in GFlops per kilowatt than the Power5 air-cooled processors.

No, not quite. Obviously user demand for computing power will continue to grow. But over the next decade, hardware will grow faster. That's just the opposite of the situation during the 1980s and 90s. That's to be expected -- the industry is maturing.

I agree. But in a decade, a "low end computer" will be the size of a small cell phone...and it'll still be more powerful than a power desktop is today.

Actually, I'll go even further than that. I predict that, within 10-15 years, the *average* person won't even own a "standalone" computer. They'll own some sort of convergence device...and will fill their computing needs entirely with it. It might take the shape of a combo computer/phone/mediaplayer, or a computer/console/videoplayer, or even a computer/food processor/whatever. But standalone machines that do nothing but "compute" will not be something the average person buys. Those will be relegated to power users only.

Add in the increase in interconnectivity thanks to wi-fi/bluetooth/etc. and the increase in internet access and functionality and I think you're on the right track.

The collection of smaller devices that work together with either an internet-based application/storage source or a combination of that and some sort of home server will handle most peoples needs 95% of the time.

It could easily end up that the most powerful computer in your house is the game console, which like we're seeing today is becoming an extension of your entertainment center and your computer anyway.

When your cell phone has the same power as an eeE PC does today along with wireless internet and some form of Bluetooth then between that and internet apps and storage most people won't need a normal desktop or laptop PC.
