use thuban for folding.
unless f@h can make use of xop/fma4, dont look at BD to outperform thubans FPU.

k10 has 128-bit fadd/ 128-bit fmul/128-bit fmisc.
BD has only one 128-bit fma4 for an FPU, thats it.
much narrower than dedicated 128-bit fadd/fmul/fmisc pipes in k10.

all they need to do is fix the process.
hit higher clocks and BD will be fine.

deneb 45nm started at 3.0, ended at 3.8.
bd +800MHz is 4.4 stocks. as the process matures.

Actually Bulldozer has a 256bit FMAC which is actually two 128bit FMACs and also has a 256bit FMISC which is actually two 128bit FMISCs

So, 1 256bit FMA and 1 256bit FMISC can occur per core cycle

1 256bit FMA is the equivalent to 1 256bit FADD and 1 256bit FMUL and a compare <-- optional

i was talking 128-bit fma per INT core.
any reference for the 128-bit fmisc? thanks!

do you have spare am3+ bracket+bkplate?

The MMX pipes are the FMISC pipelines they do all the legacy work except for x87 which is emulated on the FMACs
