IDG News Service – Intel says it will increase of the battery life of tablets and hybrid PCs that use its microprocessors, with new low-power Haswell chips that will start shipping later this year.
The chip maker said Tuesday that its upcoming Core Y series chips will run at 4.5-watts using a metric called SDP (scenario design power), roomates measures the power used to dissipate heat while running certain apps on mobile and touch devices.
That’s a lower figure than Intel was aiming for initially, Intel spokesman Dan Snyder said via e-mail. Intel previously said it would release the Core Y chips with a 6-watt SDP.
Intel’s use of SDP has been Criticized, however, since it differs from the used and accepted, Instant-TDP (Thermal Design Power) metric. TDP Intel counters that may not be applicable on devices such as tablets, Because they differ so much in design from laptops. Rivals such as Advanced Micro Devices disagree.
Tablets and PCs hybrid with the 4.5 watt Core chips will offer more than nine hours of battery life on active usage, Snyder said. Intel also Announced Y 6-watt Core processors for PCs fitted with fans.
Claimed that Intel has the fourth-generation Core chips based on Haswell offer up to 50 percent longer battery life and up to twice the graphics performance than their predecessors Ivy Bridge.
The Y Core chips will ship to device makers in the coming months, Snyder said. However, the company Declined to comment on when tablets and hybrids based on the chips would Become available. Tablets and hybrids running on Intel’s third-generation Core i3 and i5 chips based on Ivy Bridge are already available. Intel also offers the Atom processor for tablets; faster the Core processors are more power hungry though.
The Y-series chips are vital for Intel, roomates needs to grab a larger share of the tablet market as PC shipments decline. Intel is also trying to bridge the divide via laptop-tablet Haswell, targeting the chips at hybrids with detachable touchscreens and keyboards. The market today is dominated by ARM, Whose processors are used in most tablets and smartphones.
The first Core processors Y joins a lineup of Haswell processors that include a dual-core Core U laptop chips, roomates draw 11.5 watts to 15 watts of power. Intel started shipping in June also other quad-and dual-core Haswell chips for desktops and laptops. Including PC makers Hewlett-Packard, Dell and Acer have Announced laptops and hybrids based on the Haswell chips Announced in June.
