Windows tablets hold within them an implicit promise: To deliver the full Windows 8 experience in a svelte tablet form factor.
\nUnfortunately, the ambitions of Microsoft and its partners have thus far exceeded reality, largely due to processor power issues. Even the lowest of low-wattage Ultrabook chips simply sip too much juice, forcing manufacturers to house their hybrids in cases full of fans\u2014a compromise that has left Windows tablets and convertibles thicker and louder than the ARM-based tablet competition.
\nNo more. Intel announced Tuesday that new Core Y-series Haswell processors capable of fitting in thin, completely fanless designs are inbound \u201cin the coming months.\u201d
\nWhile Intel had previously announced its Core Y-series chips would run at a scenario design point\u2014basically, an Intel metric for the power draw during sustained workloads\u2014of 6 watts, the newly announced processors will dip all the way down to 4.5W SDP. (6W variants will also be available.) That 1.5-watt difference between the two is the difference between needing additional cooling and a potentially fanless design, according to Intel.
\n“\u201dI think there is a real market need for a fanless tablet or 2-in-1 with PC-level performance,\u201d says Moorhead.”
\nTablets and hybrid PCs with the 4.5-watt Core chips will offer more than nine hours of battery life on active usage, Intel spokesman Dan Snyder said via email.
\nDon\u2019t expect to see crazy performance from such low-powered Haswell processors, however.
\nWhile the new chips will be able to boost to higher performance for short periods thanks to their 11-watt thermal design power rating\u2014a \u201cworst-case\u201d power metric that measures the maximum energy used during heavy workloads\u2014a large part of Intel\u2019s ability to bring the cooling and power requirements down so far lies in underclocking the processor. Sustained boosting above 4.5W would likely strain the cooling capabilities of a fanless chassis.
\nEven still, a low-powered Haswell processor will blow the pants off both ARM chips and Intel\u2019s own Atom CPUs, performance-wise, bringing true Ultrabook-like chops to a truly tablet-style design.<\/p>\n

Haswell tabletPCWorld (US)Intel\u2019s Haswell-based hybrid reference design, as shown at CES 2013. It\u2019s skinny.
\n\u201cI think there is a real market need for a fanless tablet or 2-in-1 with PC-level performance,\u201d says Patrick Moorhead, president and principal analyst at Moor Insights and Strategy. \u201cThis is exactly where Intel\u2019s new 4.5-watt [chip] comes into play\u2026 Even though the 4.5-watt Haswell will be clocked lower than the 6-watt version announced at Computex, it will have significantly higher performance than BayTrail.\u201d
\nWhile Moorhead expects production of low-watt chips to ramp up sometime in 2014, Intel says the first round of energy-sipping Y-series processors will be produced in limited quantities. It\u2019d be a shock if those chips failed to show up in a Haswell refresh of Microsoft\u2019s Surface Pro tablet.
