Intel's Perlmutter details 22nm Haswell-based Core family

Intel's Perlmutter details 22nm Haswell-based Core family

Intel's Haswell chips, due next year, can perform like an Ivy Bridge chip at around half the power.

At its annual Developer Forum last night, Intel unveiled details of its upcoming Haswell architecture - now officially confirmed as due to drop in 2013 as the fourth generation of the Intel Core processor family.

In a presentation to attendees, Intel's David Perlmutter highlighted some of the biggest user-facing changes to appear in Haswell including a massive change in the power characteristics: compared to the second-generation Core processor family, Haswell chips will reduce idle power draw by more than 20 times. The Haswell architecture will also be used on a new family of low-power processors launching in 2013, some of which will feature a thermal design profile (TDP) of just 10W.

'The fourth-generation Intel Core processor family and our new line of low-power processors will usher in an era of unprecedented innovation in mobile computing,' claimed Perlmutter at the event in San Francisco last night. 'Our focus to deliver even lower power with the great performance that our processors are known for is as fundamentally significant as when we shifted our development focus beyond sheer processor speed in 2001. As a result, you'll see our customers delivering sleek and cool convertible designs, as well as radical breakthrough experiences across a growing spectrum of mobile devices.'

Those mobile devices will, naturally, include those built to Intel's pet Ultrabook specifications. With reduced power draw, system builders will be able to increase battery life without changing the weight or size of the laptop, or make it smaller without sacrificing runtime.

Perlmutter's announcement wasn't just about the power savings Haswell will bring to the Core family, however: details of the integrated graphics technology which will join the Haswell CPU cores on the fourth-generation Core processors were provided, promising double the performance over existing Ivy Bridge-based chips.

Combining the reduced idle and lower peak power draws of the upcoming 22nm Haswell processor cores with the next-generation Intel HD graphics technology will be key, Perlmutter claimed, to producing next-generation ultra-mobile devices. Compared to Ivy Bridge, a Haswell chip can run at roughly the same performance in just half the power envelope - a fact that will make OEMs sit up and take notice.

The biggest change for Haswell, however, was announced by Kirk Skaugen in a presentation following Perlmutters: a shift to include the platform controller hub into the same silicon as the central and graphics processors. This is key to the power savings promised from the fourth-generation Core chips - although Skaugen also hinted at other power-saving features which are being kept under wraps until closer to the 2013 launch date.

During his presentation, Perlmutter also discussed the shift to 'perceptual computing' - a system whereby the user's intentions are interpreted through a variety of human-like senses, rather than through a keyboard and mouse. Key to this shift in usability, Perlmutter naturally claimed, is the Intel Perceptual Computing Software Development Kit, due for release later this year. Aimed, of course, at Intel Core-based devices, the SDK will provide gesture interaction, facial and voice recognition as well as augmented reality capabilities for developers.

10W ... oO ... ultra low power office computer incoming :D

As pleased as I've been with the past few generations of Intel gear I can't help but wish AMD had something to match in the performance stakes.

Sure, it's a while till 2013 but I'm not gonna hold my breath.

this is what I like about competition (ARM), since ARM is really the grand daddy of low power processors, Im pretty sure it forced intel on focusing in the power draw their processors. yey progress :)

Could be good for office pcs

so will we see a big jump in speed or just low power consumption? it doesnt really seem to mention the actual speed of the cpu just mentions better integrated graphics and low TDP which for me wont be worth hanging about for in terms of a desktop cpu, laptop on the other hand... does this mean no need for a separate gpu in a laptop now?

Wonder if they used thermal paste or solder this time...

Haswell will be good for ITX!

Funny how Mr.Halfacree does a perfectly decent precis job this time, when it's the beloved, infinite and wise i. Check out the silde-show at Anandtech though; boring as ditch water but what the hell. Intreasting thing missing from precis though; IPC. 10% over Ivy, according to the i-infinite wise. [excepting fmac3 I suppose] 10%! How utterly poor. It seems to me the i-god may regret not sacrificing a bit of profit next year and going for quad low end and hex-core midrange. If AMD doesn't screw up again with Steamroller, Intel could be in a world of hurt, with only Ivy-E/EP holding their incredibly dense low volt heads above water.

Why thank you, you're too kind!

Well i'm torn now. Was going to get a 3570k with liquid metal tim under the heatspeader. Now im just thinking of keeping my I7 920 for a bit longer then going haswell.

I agree with your thinking. Not worth upgrading your current CPU till you see the Haswell in action.

Well this looks really interesting, this will be great for office and smaller builds :)

This, a prodigy style case and Hyperspin 2.0,Netflix and steam would be a killer combo for the living room.

It's funny though, back when first 5V Pentiums came out almost 2 decades ago they were considered extremely hot (in terms of power consumption rather than performance) yet they were ~15W chips. Intel actually had to lower the operating voltage (to 3.3V) AND move to a smaller production process to raise the frequency ... but noadays small double digit wattages are considered suitable for portable use, sometimes even without forced cooling :D

I'm not really interested in puny mobile devices - what I want to know is "will there be high-end, 8+ core Haswells" :-)

True, that reminds me of my first time opening a computer, there was no heatsink on the CPU back then :D.
