1.6 Duron will be equal to 1.0 Athlon.
or in other words, consider Duron as Celeron and Athlon as Pentium series of processors. obviously making Athlon more powerful then Duron.
get Athlon Palomino core processor (started from 1500+) but actual clock will be equal to 1133 around. you'll get 266FSB, SSE Integers and 3D Professional extensions. and more power than AMD Duron.
