Anandtech published The Haswell Ultrabook: Core i7-4500U Tested
A quote from the article:
I don’t think I had a good grasp on why Intel’s Haswell launch felt so weird until now. Haswell less than a month after the arrival of a new CEO, and it shows up a couple of weeks after the abrupt change in leadership within the Intel Architecture Group. Dramatic change at the top is always felt several levels below.The Haswell Ultrabook Review: Core i7-4500U Tested @ Anandtech
To make matters worse, there are now four very important Haswell families that need to be validated, tested, launched and promoted. There’s desktop Haswell, mobile Haswell, ultramobile Haswell ULT (U-series) and Haswell ULX (tablet, Y-series). The number one explanation I’m getting for why we don’t have a socketed K-series SKU with Crystalwell is that everyone is already too busy validating all of the other variants of Haswell that have to launch as soon as possible.
