Haswell to Bump Active Battery Life ~50 Percent, Increase Standby Time 20-Fold

New chips take voltage regulator module (VRM) off the motherboard for the first time, into the package
As Intel Corp. (
) continues the wind-up towards the launch of its latest generation of Core processors powered by the 22 nanometer (nm) architecture refreshed
, details about the chips' performance continue to trickle out.
I. Power Improvements Galore
In addition to monstrous performance, Rani Borkar, corporate vice president and general manager of the Intel Architecture Group, promises that
will be Intel's most efficient CPU yet. The second-generation 22 nm node is expected to deliver around a 50 percent bump in active battery life, Mr. Borkar said in a pre-
as low as 10 watts TDP
is expected to cut that down to a mere 7 W TDP.
If that's not enough to impress buyers, Intel's new chips are supposed to bump idle and standby life by as much as 20-times over
, meaning you'll be able to hibernate a machine for weeks or months even without plugging it in.
The key to
's gains is a new "smart" power controller unit (PCU) that monitors every part of the chip -- from the graphics to the CPU cores to the I/O units. The PCU can dynamically regulate power allotted to each part of the circuit as needed. This contrasts decades of past designs where clock speed (and power driving it) was often wasted on idle units.
Haswell cuts core power consumption via a new smart power regulator, brings the voltage regulator module inside the package for the first time, and offers more efficient interconnects.
supporting chipsets also offers improvements on the power electronics front, featuring a leaner voltage regulator module (the motherboard component that converts the higher board voltage down to a lower voltage level usable by the microprocessor die). With
the voltage regulator is integrated inside the chip package for the first time (removing it from the motherboard), which will allow for smaller motherboards.
That should be helpful to Microsoft Corp.'s (
push for 7-inch and 8-inch Windows 8.1 tablets
. The explosion of this lower-priced segment helped propel another struggling tablet platform -- Google Inc.'s (
) Android --
from a bit player
to a serious contender, with designs like the Samsung Galaxy Tab, Amazon.com, Inc. (
) Kindle Fire, and ASUSTek Computer, Inc. (
Nexus 7 tablet
The 7-to-8-inch segment offers lower prices due to the smaller screen size. The form factor was popular enough even Apple, Inc. (
begrudgingly jumped on the bandwagon
with the iPad Mini.
II. Windows 8.1 and
-- A Winning Duo?
The new Intel chip will also have embedded DRAM (memory), which should help further cut down on external components in small form factors.
that the GPU will have 128 MB of dedicated DRAM in some variants. The new chip also offers faster interconnects, another factor helping it hit the 7 watt envelope.
Intel has already shared that
cores' revamped on-die graphics processing unit (dGPU) are expected to
increase performance between 50 and 300 percent
, depending on the model. Intel has, for the first time, offered a distinct branding for its dGPU, dubbing it "Iris". Demos showed Iris
handling popular RPG/slasher/spellcasting game The Elder Scrolls: Skyrim
with with ease.

More details of the new chip are expected to come out in two weeks at Computex, which runs June 4-8 in Taiwan. A number of OEMs are expected to show off
based designs. More designs may pop up at Microsoft Corp.'s (
conference, which will be held June 26-28 in San Francisco, Calif. At the conference Microsoft is expected to offer up a Release Preview of Windows 8.1, the free revamp to Windows 8, which Microsoft hopes will win back critics.
In many ways Intel and Microsoft's fates are tied together. Q1 2013 marked
the worse percentage drop in PC unit sales in history
. But both companies are hoping that the market reacts strongly to
+ Windows 8.1
ultrabooks, hybrids, and tablet computers.

Actually, windows is the primary OS for most AEC CAD/BIM and Graphics applications. A relatively small percentage of Architecture firm run Macs, and almost none run Linux/Unix. Construction is pretty much entirely windows based, with the exception of mobile device access which is actually dominated by iOS, not OSX or any desktop OS. That said, there is a strong trend starting towards windows 8 for mobile devices in AEC - time will tell if it sticks or not, but many companies are mid-pivot in switching to that platform and the rest are testing it.
Also, 4K is great for boring documents and particularly spreadsheets on large-screen monitors. Most of our estimators and accounting staff deal with MASSIVE spreadsheet or table based applications daily, and they all love their 27 or 30 inch monitors because they can see more of their spreadsheets. Give them a 52" 4K screen and they'll worship you - literally. I'm quite sure they'd build little alters out of post it notes and aluminum foil from their brought from home lunches...
Your stereotypes are more accurate for graphics design work, or custom manufacturing CAD solutions - but the primary producers of the "defacto standard" software products for creative and CAD work sell a much higher number of licenses of windows applications than they do of OSX applications. There are of course exceptions (particularly those that only offer OSX versions) but for most of the cross-platform solutions this is true. So, either you're mistaken or creative and CAD types with OSX or Linux boxes are also thieves and steal licenses thus skewing the counts...

Perhaps in your singular place of employ, they use more Windows. But industry wide? Lol. No. Trust me, I know, until just last year, I was in unix workstation sales. It is very industry dependent, but across the board, serious workstations do not run Windows.
Secondly, no, a 4k screen would not be good for your bean counters at all. Windows does not have resolution independent fonts. And until it does, it will be horrible on high-res screens. All your fonts will be so tiny. Sure, you can set them to larger sizes, but then send your document to someone with a normal screen, and it'll be all out of whack. This is a Windows OS deficiency. OSX and Linux already have resolution independence. Microsoft is, as usual, the slow kid in the neighborhood, always last and always playing catch-up.
