Intel's fanless and energy efficient Haswell chip coming later this year

Could the future version of the Surface Pro have Intel's energy efficient Haswell chip inside?

Intel may have launched its fourth generation core processor, code name Haswell, in early June, but the chipmaker is already planning to launch another version of Haswell that will use less energy and will not need a fan.

CNet.com reports that, according to an Intel spokesperson, the new Haswell processor will cut down its power rating to just 4.5 watts, versus the current lower limit of 6 watts. In addition, the spokesperson said it will be the first member of the Core family of processors to be fanless.

What does this mean? Well, that means that in theory, the more powerful Haswell chip could be put into thin and light notebooks, tablets and hybrids but still provide those products with a better battery life compared to the regular Haswell chips. Intel already has a low power processor design, code name Bay Trail, that's due to debut later this year in Intel's Atom, Celeron and Pentium chips, but Bay Trail doesn't have the performance of Haswell-based Core chips.

Intel says that the fanless and power conservative Haswell processor will be made available in limited quantities later this year. It's not much of a stretch to speculate that it could be used inside a future version of Microsoft's Surface Pro tablet. The current version, which launched in February, has the third generation Core i5 processor inside.

This is the lower limit so relates to when the chip is idle. Is having slightly less power consumption when it's doing nothing really going to save much power? I'm more interested in how much power it uses when it's under full load compared to previous generations.

"Full load" is also not a fair comparison, especially with so much offloaded off the CPU in day-to-day use. I'd be interested in seeing what typical usage scenarios get. I get about 2 hours of full bore production work out of my surface, but with tweaked power settings can get 4-5 of media/web consumption in the evening. The scale is wild.

That said, the idea of it being fanless means that even under full load it'llb e able to distribute it's heat load without a fan...lending me to believe it's full voltage is decreased significantly too

It isn't really news, been waiting for haswell notebooks for few months. Mac has already put it into new macbook air. Can't wait for new surface pro with haswell processor. thiner, lighter and more battery life.

I think the article is referring to the bay trail processors, not the Core processors. I mean leaks are never 100% accurate, however the new bay trails are going to be INCREDIBLE in a tablet.
Model--Family--cores--clock--Max GPU--SDP--TDP
Pentium N3510--Bay Trail-M--4--2.00GHz--750MHz--4.5W--7.5W
I don't think something like this will make it into the surface however - they will keep the RT with an ARM and the Pro with a Core chip. Pitty...because I would pay good money for a Surface with this chip in it...

They are not referring to Bay Trail chips.

I've got a Surface RT and it's great for surfing the web & casual games in front of the TV, but I'd like to eventually get a Pro... but it might not be until Surface Pro 3...

interesting. Looking forward to Surface 2.
Two things that are holding Surface Pro from being the ultimate tablet to rule them all is
1) Bulkiness
2) Battery Life
Fanless Haswell can address both. Dreaming about a thinner Surface Pro with 8 hours+ battery life and 256Gb SSD. Put on it Windows 8.1. DREAM.

Then they make the announcement of needing liquid nitrogen j/k

This should be put into more standard electronics, phones and the lot wont need this. But Intelligent Microwaves or fridges or toasters!

"the more powerful Haswell chip"

Just to be clear, Haswell isn't a “chip”, it's a family of products sharing the same or very similar design. A Haswell family chip at this TDP could be woefully underpowered, and who knows, might even be equalled by an Atom in single threaded performance.. the new Atom family does look interesting. We'll see reviews when the chip is released (but yeah, it's still an interesting unit)

Actually no, its the code name of a microarchitecture, upon which chips are based. So both are wrong

Which is the same as saying a family of products based on the same design

Don't get your hopes up...

It's in "limited volumes". Intel also had a very low power version of Ivy Bridge last year in limited volumes and that saw basically no usage in anything (including the current Surface Pro).

The next Surface Pro will likely use a more standard Haswell part (like the 6W SDP version) which needs a fan. The battery life on Haswell is VERY impressive though (check out the new Macbook Air), so it will still solve the main problem everyone had with the Surface Pro - battery life.

It will likely be the Surface Pro 3 that will be fanless, when Intel release Broadwell next year. That will be a 14nm shrink of Haswell.

That chip wasn't seen in any products until June which is probably part of the problem.

I think that's what he meant by perform... if it gets close tosnapdragon in power and keeps it processing power up, and is affordable then it will be a gamechanger.
