Dual E5-2680 Low PPD?

I turned up my first dual E5-2680 host and it's getting 252K PPD on 8101 (16:46TPF). I confirmed with turbostat that all 32 cores are running at 3.1GHz.

I have it configured with 8 4GB 1333MHz sticks of ECC RAM.

I thought I had seen quad E5-4650 systems hitting close to 1M PPD, so I figured this system with half the cores, but a little faster clock, would be somewhere around 400+K PPD. Is my PPD pretty standard for this setup?
 
The 1 mio PPD I have seen were with 8102 and 8104 and with 8101 it was 666k PPD.

For your reference:
My dual E5-2687W does 8101 TPFs in 15m13s (it is currently running 8101)
 
BTW, forgot to mention. The relationsship between TPF and PPD is non-linear.

I noticed an 8105 WU got 353K PPD. Not bad for a dual-CPU rig. :)

Nope not bad at all.
High end Intel 2p can generally compete with a low-mid end AMD 4p box (no oc).
Of course the Intel solution generally costs more...lacks overclock-ability...
but uses less power.
 
Its not that bad if you compare the spicy versions...
The performance and power efficiency are there...

I have two retail E5-2680's and four spicy. The client with retail CPUs is pulling an average of 279W while the two clients with spicy C0 CPUs are pulling an average of 295W. The only other difference is the retail client only has 8 DIMMs while the other two have 16 DIMMs.

Think the DIMMs are worth 16W or is part of the difference the spicy CPUs? Any bets?

2w ea. I wouldn't be surprised... what DIMMS?
