The only hope I see for folders here is if the gromacs folks can optimize for the new SSE instructions. But those guys can take quite a while to get these optimizations done due to the needed reliability of submitted results. Maybe these Bulldozer chips will do well in the multi-processor boards.

Even then, with these power numbers....
I've completely stopped GPU folding. With Donkey McDinkey's new power plan, I figure I might as well save money now by eliminating the extra power consumption right now.

Realistically though, a used I7 970 or one of those E5645 server chips would be far better investment than bulldozer.

Seriously, though - Bulldozer's failure to keep up in single- or lightly-threaded applications really oughtn't come as much of a surprise to anybody. It's failure to keep up in multi-threaded applications, though, is an absolutely shocking finding that undercuts the whole raison d'Ítre of Bulldozer. here are my takeaways:

It's a poor chip for ordinary users; It's a poor chip for gamers; It's a poor chip for crunchers; and, from the indicators that hint at SMP performance (wPrime and Cinebench), It's a poor chip for servers. In sum, Bulldozer has failed to appeal to ANY market at all, not even AMD's traditional stronghold in the budget category. AMD has pulled some fail over the years, but this has got to be the most epic of them all!
I guess I'm not that disappointed that I recently lost patience and invested in an I7 2600k running at 4.7Ghz.

I guess just like Phenom II was an improvement over original Phenom, we can now look at PileDriver as being the next step for folders.

Really this was not a surprise to me. Whenever AMD has "delays" it seems like something is "wrong".

Blah. I guess my next server chips will be Opterons lol.
