Haswell’s launch is a little disappointing, even though it does bring a small improvement to performance. When it comes to CPUs, we are a greedy lot, but Intel made us that way. When Intel launched Nehalem (the first gen i7), the performance improvement over its predecessor was roughly 20%-30%.
This was repeated with Sandy Bridge (second gen), which brought an improvement of roughly 25%. Ivy Bridge (third gen) did not maintain the pace, offering only a small ~5% improvement, but we forgave that, since it was just a die-shrink. Haswell was supposed to bring back the excellent OC-ability of SB, and also bring excellent improvements to performance as well as power consumption.
