As none of you really like going to foldingforum I thought I'd copy this over.
The debate on the benefits of hyper threading for F@H has raged back and forth as long as I have been folding and I saw it mentioned yet again recently but I have never seen anyone test it out. As I have just had to rebuild my 3rd rig I thought it would be the ideal time to do a couple of tests.
The rig consists of dual E5-2670 retail xeons, Asus Z9PE-D16 mobo, 18gb of ram, corsair AX760 psu, a usb2 flash drive running the [H] folding appliance v9 with the kraken. The WU used is P8823, R0, C3,G254
HT on.
Idle power 87w
Folding power 312w
tpf 2:31
PPD 139k
HT off.
Idle power:- 83w
Folding power:- 260w
tpf 3:46
PPD 73k
So that's a tpf that's 50% quicker, 90% more PPD and only 20% more power. Looks like using HT is definitely a must to max performance.
I know its only one wu but I'm not about to start dumping WU just to run tests, i'll run another test in a few days and see if a different WU shows any difference.
