Thanks NTCompatible for the heads up on this review. Tom"s Hardware has posted a comparison between the 1,1GHz Duron and the 1,2GHz Celeron
Currently no CPU offers more performance for less than $150. AMD and Intel unveil their fastest low-cost processors for the bottom end of the market. AMD expands its Duron series with a 1100-MHz variation - Intel keeps up with the competition by offering the Celeron 1200 in the same class. One thing is certain at any rate; the top models at the beginner level were never to be had so inexpensively! However, both CPUs are equipped with state-of-the-art technology and, seen in terms of value for money, are absolute front-runners - you just can"t get more power for your money. Among these, the AMD Duron 1100 wins honorable mention: it only costs $102 and fits into all Socket 462 boards (Socket A).
In the all important age of getting value for your hard earned cash, We recommend that you check the review before deciding on what to upgrade your system to. AMD or Intel, I wonder.
