Intel’s next generation Haswell CPU architecture is set to lower the bar even further on power efficiency by requiring only 10W of cooling. As the company’s mainstream processor, and replacement for Ivy Bridge, it is set to launch in the first half of 2013.
Haswell will be based on a new socket called LGA 1150, and is said to feature incremental performance improvements over Ivy Bridge. Further, Haswell CPUs will include one of three tiers of GT1, GT2, or GT3 processor graphics along with the AVX2 instruction set.
What is interesting about the recent report by The Verge is that previous rumors suggested that Haswell would have higher TDP ratings than both Sandy Bridge and Ivy Bridge. Considering Ivy Bridge has several 35W desktop models, and a few 17W mobile parts, the reported 10W TDP of Haswell seems to indicate that at least the mobile editions of Haswell will actually have much lower TDPs than Ivy Bridge. (It is not clear if detkop and non ultra-low-voltage (ULV) chips will see similar TDP improvements or not.)
The 10W TDP would mean that ultrabooks and other thin-and-light laptops could use smaller heatsinks and suggests that the processors will be more power efficient resulting in battery life improvements (which are always welcome). The Verge further quoted an Intel representative in stating that "It's really the first product we're building from the ground up for ultrabook."
While the lowest-power Haswell chips won’t be powerhouses on the performance front, with the improvements over Ivy Bridge to the CPU and GPU it should still handily best the company’s Atom lineup. Such a feat would allow Haswell to secure a spot powering future Windows 8 slates and other mobile devices where Atom is currently being used.
Just the fact that Intel has managed to get its next generation mainstream CPU architecture down to 10W is impressive, and I’m looking forward to see what kinds of devices such a low power x86-64 chip will enable.
Stay tuned for more Haswell news as the Intel Developer Forum (IDF) next week should be packed with new information. Here's hoping that the desktop chips manage some (smaller) TDP improvements as well!
