Are Durons/Thunderbirds faster at cracking than classic Athlons?

No....The best speedup for the Athlon/TBird/Duron series is the 4.63 client of RC5....Assuming you are talking about RC5? The other projects I'm not sure about!

Good Luck!

😀

Sorry, I should have read your Stats in your sig!
 
RC5 client is not heavily dependent on a large cache size so one can obtain the same performance between TBird, Duron, and a classic Athlon.

As Engineer said, be sure you use the latest version of the dnet client. There is a significant performance increase between the latest version and previous.
 
Cache is not a factor in RC5, from the benchmarks people run it appears only 2 things are important: clock speed and chip architecture. Despite their varying cache speeds and sizes, Pentium Pro, Pentium 2, Pentium 3, Celeron, Celeron 2, and Xeon processors all have the same correlation between clock speed and cracking speed. Why? They all use the same basic P6 architecture. Same goes for comparing Athlons, Thunderbirds, and Durons.
 
Actually, I'm seeing an eency, teency tiny speed difference here. As luck would have it, I have two of the same speed at the shop right now; a TBird 700 and a Classic 700. The TBird is doing about 30K more. Both are on ASUS K7M motherboards. But, the systems aren't identical accross the list, so there could be other factors at play.

That's a 1.26 percent difference Russ...between the different system setups and statistical error, I'm not sure if that would be a large enough difference to declare a definite advantage for the TBird. It would be interesting if you could get them on the same board and allow each to run a large number of blocks to see if it's the system or processor that is causing the variation.
 
Russ I tend to agree with you. I did not bother to mention it since it is such a small difference.
Using the numbers Engineer gets with his TBird 1000 and my numbers from a classic Athlon at 1100, it appears that if Engineer OC'ed his TBird to 1100 he would be some small percentage ahead.

Since TBird does have an on die cache this is believeable.

If you compare SETI between TBird and a classic Athlon the improvement on the TBird would be significant.
