Intel's Game Changer: One Size Fits All Haswell

26 thumbs up
Intel offered dozens of technical seminars this past week and they all touched on power efficiency to one degree or another. Intel has proposed power efficiency improvements to the memory bus, CPU-PCH linkages, SATA, wireless radios, displays, and much more.




Part of that rethinking process is focusing on seemingly settled interfaces and how they function. PCI-Express optimizations and the general shape of Intel's power optimization framework are shown below.



Here's Intel's next-generation platform, Shark Bay.



LTR refers to Latency Tolerance Messaging, a way of informing the platform how much a device can idle without compromising responsiveness or capability. By 2013, Intel expects the majority of devices that hook into Shark Bay to support some type of additional low-power operation. Long-term, the company's goal is to turn as many of these blocks green as it can.

You're right Joel, power considerations are going to steer the market of the future.

I wonder if the competition has any Rabbits in their hats?

Haswell is looking to be a killer chip for sure.

It was very interesting to read about new processor from Intel. I think it is good to reduce the power of CPU. I am looking forward to read next gen Intel CPU for desktop and next Extreme Edition Series from Intel

Realneil,

Not unless they can break the laws of physics.

This intel guy holding the CPU looks like he's passing something righteous!

I don't see where any changes to the laws of physics are necessary to make this happen. They are simply turning off circuitry when it's not being used and providing different levels of performance to meet varying demands. Balls out the chips still gonna suck power and dissipate heat, but when it's doing lighter tasks, it can turn parts of itself off or slow them way down that aren't being used and save power. The complexity of such circuits relative to the rest of the processor is probably fairly trivial. It is sad that they are focusing on one OS vendor, Microsoft, because Windows-8 frankly blows. I'd much rather see them do a good job of documenting so that Mac, Linux, BSD, and other OS's can ALL benefit from these capabilities.

Pushing Haswell down to 10W is an even greater achievement, but hitting these targets requires a great deal of collaboration and cooperation.

I work for Intel and they got it to 7W not 10. This is also public knowledge.

I'm writing a paper on this for my "Organizational Report Writing" class. The chip seems stellar.

This is all pretty impressive.

It sounds like although its power consumption is being decreased by a slight amount, the number Intel is reporting is correlated with what the CPU is doing while still being "on"

It's good to see some improvements and that power consumption is dropping when it's in minimal use or idle but what's really important is finding a way to decrease power consumption in heavy top side loads since most people buy computers to use them, not try and keep them to minimal or idle use.
