I have an Athlon and it has a LOT of settings to tweak to get full speed. Interestingly, my Motherboard's setting for "highest performance" does NOT achieve that high performance. Other settings *must* be adjusted. Without these adjustments, the Athlon can't even keep up with a P-3 at equal speed. WITH the adjustments, the 1.4 Ghz Athlon is very competitive with the Intel P-4 at 2Ghz in my own tests, with my own testing program. (Besides costing quite a bit less, of course!) The second point which concerns me is that your test program may inordinately penalize a computer if it has only the 256Megs of memory that the Athlon had in this test. Assuredly, one of these (and maybe both) is the explanation you seek. Dave
