Look when Intel will make a 11 nm cpu, they will be able to create one that has 16 cores running 32 threads at more than 5 GHz at a maximum TDP of 65 watts. That will be enough to keep all apps and processes running without delays. Then I will be able to play Hearts, send an email, receive an instant message, watch a video, check penny stocks, keep my antivirus, antispyware, firewall running and cure cancer. I hate it when I'm trying to cure cancer but my cpu is too slow and I have to delay curing cancer in order to keep playing Hearts.
Computers for 99% of home and corporate users are already fast enough. There's no point to increasing speeds and performance of cpu beyond just doing it for the fun of it. 6 cores and 12 threads is enough to do anything you want to do. If you're experiencing delays, it's caused by your software's bloated coding, not your cpus. If you don't know that, forgetaboutit.
