The new processor series codenamed Haswell is here to replace the Ivy Bridge series. There is a significant performance improvement, that's for sure, but is it enough to warrant changing from Ivy Bridge to Haswell?
I would have to answer that question with a no. It is not worth it if you want to upgrade your PC to play games, or simply for general everyday tasks. On the other hand, there is a great improvement when it comes to the encoding tests, which would help many people out there. For those who want to upgrade and replace something older than the Ivy Bridge series, it is all based on the price and one's needs.

All in all, after looking over all the results of the benchmarks, I am, to be honest, not that excited about the Haswell series. I do not know why, but it may be due to the low overclock we achieved. 4.2 GHz is ridiculous; it takes me back to when Clarkdale processors required 1.5V to reach 5 GHz. Still, I hope that my retail processor's poor overclock was a result of bad luck and nothing more.
