It has been some time since the Pentium 4's were the top of the line, and as I am sure many of you remember, Intel's fastest P4 was 3.8 Ghz. Although it was very inefficent, you have to admit that it was clocked very high. When do you think we will see non high-end consumer chips that reach 4Ghz? I realize that Intel redesigned their chips to be way more efficient when they moved to the Core archetecture, but also lowered their Ghz numbers by quite a lot (even though they were faster than their higher gigahert counterparts using the older technology). Thoughts? edit: 2014, we now have a 4.0GHz option in the new iMac!
