Of course it is, so was 533 and 400. 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).
