Heya... does anyone know how well/better the AMD Barton CPU does with UD cure for cancer or other Distributed computing platforms?

I know that UD likes FPU most of all, then Mhz, then memory bandwidth (up to a limit). So how important is that extra 256k of cache?
*curious*

Just my 2 cents
My 2.0 celeron 128k is = too my 1.3 celeron 256k
counting 2.0 has pc2100 - 1.3 has pc133
I tested a p4 2.4 but it used pc133 and that slowed it
a lot,
2.2 celeron 128k with pc2100 = too P4 2.4 512k with pc133

OUCH. yes. sdram will hold your system back.. especially with a p4's architecture.

I noticed with AMD systems that 133mhz sdram was did hinder performance of UD.
150Mhz sdram gave moderate performance boost.
Interestingly when i changed to a efficient DDR system (KT333) the performance benifits of upping the ram stopped.

E.G. 133/133 gave just as much performance as 133/166 or 166/166. Memory bandwidth was completly satisfied with 133mhz DDR, the rate determining step being CPU power.
