Review Zone heeft een 15 pagina tellende Athlon vs PIII comparison online gezet. Hier heb je een hap uit de conclusie:
Now for the recommendations. Clearly enough, the Athlon is the winner here, and we strongly recommend the Athlon 600MHz and the Athlon 550MHz when considering their price and their performance. The 650MHz version is the most expensive out of the lot, because itís the fastest processor available. Naturally, if $950 isnít a big deal for you, the Athlon 650 is the best choice for you. However, if you currently own a BX motherboard and are looking at the cheapest upgrade without having to spend more money on motherboards, you can either opt for a 500MHz Pentium III since itís now $270 or a Celeron 500. You may as well go over the 500MHz mark if you haven't already, rack up some horsepower for postmillenial demands on computing power.
Thanks to the EV6 bus, the future of Athlons on multiprocessing systems looks very promising as well. Once the 100MHz system memory bottleneck is lifted, the Athlon system will offer support for PC-133 SDRAM or faster. At the moment, Athlon boards offer Ultra ATA-66 support and AGP 2x, while AGP 4x support will take a bit longer to arrive on the scene. More interestingly, not only has the Athlon has been designed in a way to scale the processor all the way up to 1GHz but whatís more, the current 0.25Ķ core seem to even scale up to 700MHz+, so it wonít be a surprise if AMD comes up with a quick 700MHz Athlon based on this core.
