Intel says its Haswell Xeon E3 will have a 13W TDP

And a GPGPU with full OpenCL support

CHIPMAKER Intel has revealed that its upcoming Haswell Xeon E3 processors will have TDP ratings starting at 13W.

After Intel announced it is sampling its Avoton Atom chips fabbed on the firm's 22nm Tri-gate process node ahead of HP's Moonshot launch, the firm revealed a few details about its upcoming Xeon E3 refresh. The firm said its Xeon E3 range will be updated to the Haswell architecture and have SKUs with TDPs as low as 13W.

Intel said its Xeon E3 processors will be updated to Haswell sometime in mid 2013, meaning it shouldn't be too far behind the firm's consumer launch of Haswell on its Core branded processors. The firm is expected to show off its consumer Haswell chips at Computex in June and already had working silicon being demonstrated to journalists at last month's Game Developer Conference.

Intel's Xeon E3 will also have integrated graphics, with the firm confirming to The INQUIRER that it will support full-profile OpenCL 1.2 and will be same as on the consumer Core branded Haswell parts, though there will be two versions of the GPU. The firm's decision to include a GPU in some of its single-socket Xeon E3 processors is a further indication that the firm is slowly warming to GPGPU and in particular OpenCL.

However Intel's revelation that it will be producing a 13W Xeon processor is really the most important disclosure as the firm continues to bring its full x86 architectures such as Ivy Bridge and Haswell ever closer to the single-digit TDP range. It should be noted that while Intel can bring the chip's TDP down to 13W, unlike system on chip (SoC) parts like its Avoton Atom chips overall system power will be higher as fewer components are integrated on die.

Intel didn't say when its Haswell Xeon E3 chips will arrive but its mid-2013 mention means the firm is pretty comfortable with Haswell and its process node, which though being 22nm won't print out the same transistors as its 22nm Ivy Bridge chips. The firm knows that 2013 is vital as many ARM vendors circle for a piece of its server pie, and Intel isn't waiting around, with Haswell Xeons turning up in a matter of months and dual-socket Ivy Bridge EP based Xeon E5 chips pencilled in for the third quarter. µ
