if this were true. all home computers would instead be "supercomputers" meaning multiple single core processors.
but EVERY hardware developer on earth knows better. and is using the hyper threading now.
if you think you know better then the entire industry, then you should write some emails.
I seriously have no idea what you're talking about; the industry uses more than one core because it wants to make the most out of the current processing power we
can produce, and adding multiple cores is the way they can get more processing power.
I'm not saying that using more than one core is a bad thing; in fact I agree that it's a great thing to do; I'm merely stating that according to the facts, if one theoretically had a 20GHz single core processor, it would outperform a quad core 4.0GHz processor.
