IL/MC performance

[Quisarious]

Just wanted to add some further info...

I had noted before that my e5-xeon rig did relatively better (based on TPF's listed in spreadsheet - https://docs.google.com/spreadsheet/ccc?key=0Aspl6-RkaxtFdHdTdUdmUjhWalpXWVZ2S2xvejBDcHc#gid=0 ) on 8101's compared to 6900's.

I've noticed the exact same thing with IL. I know the speed of the IL FPU arrangement is quite dependent on the type of load applied (since it has its own scheduler). Perhaps there is something about the new 8101's that works better. It's interesting the same phenomenon occurs with the Xeons...shrug.

Anyway, some data:

I have 4x6282 with turbo on (base 2600, all core turbo 3000). On 8101's the cores run 2680-2720. On 6903's they run 2740-2770, on 6904's they run 2750-2800.

TPF's as a percentage of Patriots 4x6190's:

8101 : 105%
6901 : 119%
6903 : 118%
6904: 120%

It's the same pattern when I compare to other people's 6100 times (so I don't think it's the case of Patriot's machine throttling on 8101's, unless all 6100's have that problem...).

I think the conclusion was that 8101 likes the memory bandwidth. That's what Intel and IL have better than MC.

Look at also my numbers with 4 x 6166HEs at 2.34GHz; I have 30 sec better TPF on 8101 compared to Grandpa's 48 core MC system at 2.475GHz: https://docs.google.com/spreadsheet/ccc?key=0Aspl6-RkaxtFdHdTdUdmUjhWalpXWVZ2S2xvejBDcHc#gid=0
That's only because my OC'ed system memory is operating at 1386MHz, 7-7-7.

My 6172s and 6272s in 4p basically reverse their relative performance on 8101s as well although the 6272s have less of an advantage than the 6172s have on 690x. I'm just hoping I get something other than 8101s pretty soon. That's all I've had on my 2 4ps for the past week, for instance. It does make a pretty consistent PPD.

given the mix of WU's you all see-which seems to be a decent mix of 8101s-and that predicting the future is generally hard would interlagos be a worthwhile purchase? Let's say 400 per chip vs 500 a chip for 6176's?


PS: Hi all. I'm Van_Arnam on the lists, got to about 170M w/ GPU folding by early 2011, been semi retired during my internship which is now almost done. looking to buy some 4p setups and have been lurking for some time here...

As a relative newb here myself, welcome and you are in exactly the right place to sort out 4P love. That's what brought me here, but the community is why I've stayed. Time to get [H]ard!
