Ok lets settle down there is no clock for clock arguement anymore and there can never again be one. Once intel releases the p4s with the 800mhz bus even AMD will be lost and so will intel simply because there will be no way to compare the 2 anymore.
As for which is faster clock for clock AMD wins in every case period form 1ghz and up. In PR rating vs P4 clock speed again there is some faulty info floating around here. From 1500+ to 2400+ palamonie and tbred the XP wins and yes i know this is debateable but it is a proven fact that a 1600+ and a 1.6ghz intel the AMD will win. But once AMD changes its PR ratings with the introduction of 333fsb. Past 333 fsb the bartons are way off period so dont even think about them but the 2600+ is abotu the same maybe alittle worse than the p4 2.66 past that it only get worse for AMD but the performance is still only measurabel in fractions of a percent.
But again it all matters on what you are doing with the CPU a rather crude analogy is a dumptruck might have 250 horse power and a ferrari might have 600hp but if you want to haul something you would go with the dump trunk. In more AI intensive games the AMD wins in more graphics intense games the P4 wins. As far as applications go many apps are and never have been truly optimized for athlon processors simply because the workstation world has never welcomed AMD cpus so most applications other than simple office applications the P4 will when.
Also your friends may have been refering to the earlier athlons like the tbirds which were AMDs golden age they had no PR ratings and at equal clock would kill a p4 in everything.
