I'm not sure what to trust out there on the internet. I've seen "Intel gets 4.9 ghz on air" mentioned in one article, and another article speculating that only one core was active and operating during that product demonstration. Other articles mention that the multiplier rate is way up, over 40 even to 45 with the FSB dropped to 100 MHz. It just seems too foreign to me and I guess I just can't get used to seeing those numbers in the specs that are published online.
Even more articles are suggesting that "getting to speed X" on air does not mean that you can get to "X + Y" on water or other deeper cooling methods. That implies there is a plateau that you hit and then that's it, you can't overclock being that, even if you had an absolute zero cooling system.
Have I just been reading some bad internet press? What are some of your expert opinions on the matter?
