Athlon 64 FX-53 2.4 Ghz 1 MB

Intel P 4 3.4 3.4 Ghz 1 MB
Intel P 4 3.4 3.2 Ghz 1 MB
Intel P 4 3.0 3.0 Ghz 1 MB
It is clear from above that the Processor Frequency of the P 4 remains much higher than all the Amd Athlon processors? Intrestingly it is even higher than the the Athlon FX 53 and 55.Don't you agree that one should consider all these thing before taking a correct decision?
Dosen't the 1 Ghz frequency difference between Intel P 4 3.4
and Amd Athlon 64 3400+ gives the edge to the P 4 3.4?

Time and again people are confused with the frequency illusion creation by intel ....though people should understand what is reality behind this hype created by intel .......best way to clear ur mind is to read the White paper given by AMD on their website ...here is link :
http://www.amd.com/us-en/assets/cont...epaper_v12.pdf
if u find it difficult to understand ....here is the simple deal ....i will try to elborate it a little
performance is given by the product of IPC (instructions per clock or as better said in the white paper as work done per cycle ) and frequency i.e,
performance = IPC * Frequency (*=multiplication)
initialy due to architectural difficulties it was not possible to increace or decreace IPC .........IPC being constant performance was proportional to frequency.....the higher the frequency the better the performance ....
but due to advancement in technologies and new fabrication processes it was possible to play around with IPC ...while pentum 4 (as white paper suggests ) choose to reduce IPC ...they have to increace frequecny .....for better performance ......but AMD choose with better optimization between two parameters ...and with its innovative "Quatispeed" architecture it was possible to increase both the parameters frequency and IPC .....that was in AMD athlon 4 processor ....but innvotion in the architecure continues ....and latest was 64 bit computing and the IPC and frequecy thing remains ...which made computing more easier and all in all better performance (how 64 bit computing made performance better is another issue and i m not dealing with it here coz u r more concerned with frequency here !)
so we get better performance coz here both IPC and frequency has increased .......unlike intel which running for frequency myth !
