Digitimes are reporting that Intel's anticipated refresh of the Haswell line of CPUs is set for May of this year, slightly ahead of previous expectations. The new CPUs - made possible by a more mature process leading to better yields and binning methods - will be comprised of 20 SKUs ranging from the i7-4790 at the top down to low-power and Celeron variants.
Exact details of the refresh aren't public knowledge but we should see an increase of a couple of multiplier bins at the top end. Complementing this release will be H97 and Z97 motherboards, with chipset shipping to board partners such as GIGABYTE beginning in April for a tandem release.
Unfortunately it looks likes those seeking something in the enthusiast overclocking bracket may need to wait a little while longer as unlocked K-series CPUs won't be available until the third quarter, coinciding with the expected release of Intel's Haswell-E server/workstation class model line. The latter should also be the first desktop platform to make use of DDR4 memory, shown off at CES last week.
