As they say, supposedly you get 3.2gb/s on the P4's "400MHz" bus, 4.2GB/s on the "533MHz" bus and 6.4gb/s on the "800MHz" bus. In reality, however, a "533MHz" bus (actually 133MHz) gets about 2.5gb/s. 4.2Gb/s theoretical, 2.5gb/s actual, thats 59% efficiency. Take the true 200MHz/400DDR bus of an AthlonXP running on an Nforce2. Whats the Max Theoretical you can get? 3.2gb/s... what is the actual bandwidth? 3.2gb/s. Plus the memory latency is MUCH lower on an Athlon board. :) Looks like Intel is continuing it's marketing BS again.. If you want to see how much a 200MHz (400DDR) bus helps an AthlonXP checkout my companies webpage, go to the benchmarks section. All of the blue results are stock speed (133 & 166fsb chips), the red results are the pretested chips running 200fsb(400DDR).
