Simple 2.4ghz Collinear Antenna How Can I Compare My Old Computer Speeds With The Ones Currently Being Sold?

How can I compare my old computer speeds with the ones currently being sold? - simple 2.4ghz collinear antenna

Is it possible to compare the processor clock speed of an old P3 (2.4 GHz) with a modern dual-core much more effectively? I do not think it is so easy with the words 2.4GHz dual-core processor is two times faster than a 2.4 GHz single-core. Right?

I am a little old fashioned. I want a unique reference number which may, at its head as the old P2, P3, P4 chips classifications as "Itanium, Centrino, and 75 different types of Pentium M". This is just confusing as hell.
