Tuning the CPU - 8GHz possible, need more time to figure out settings

is piledriver slower than bulldozer in 1M? I see a lot of high freq results that should be faster than they are.

Yes, it is. You need ~300-400MHz to compensate the bad performance.

Thats about right in my book.

 

- At 7.81GHz, Bulldozer could do 11s flat (really good efficiency). Massman is running 180MHz faster, yet scoring 281ms slower.

 

- I did 11.076s@7.782GHz on FX-8120 (not great efficiency). Massman is running 200MHz faster than me, but .2s slower.

 

- On Bulldozer, there are only 4 SP1M submissions above 7.9GHz, but all four are under 10.8s: http://url.hwbot.org/10PpQZt

 

So basically, at the same frequency of 7.9-8GHz, Bulldozer was about a half second faster than Piledriver in SP1M. With the right efficiency, 11.281s sp1m should be doable on bulldozer around 7.6GHz.

 

Really though, hardly anyone bothers running sp1m or sp32m on bulldozer or piledriver under LN2. No one has even ran sp32m on Piledriver above 7GHz.
