don't disagree.
but in the OP, he did phrase it as an open question for PG to comment on.

They have not, so he is just refining his calculations as best he can with the limited information he has. :wink:

Well - as for the 2.5x there is also some uncertainty as to what it applies to. Best case or Worst case? (We know performance can vary a lot depending on what forces and physics are turned on). Old Gromacs (pre-4.6) or new? OpenMM 5.0 or 5.1? (both have seen substantial perf increases in recent revisions). I would not recommend using the number as fact and then accusing PG of being unfair with points if the math doesn't line up (I am not saying you all are - but someone will). At this point all I would be confident in saying is that Gromacs is much faster than core 17 running with opencl on the CPU.

I appreciate the healthy criticism regarding my spreadsheet, it is well deserved. I'd like to remind you about the disclaimer I put into the spreadsheet itself, though:
HOWEVER, keep in mind that ultimately
THIS SPREADSHEET IS FOR AMUSEMENT VALUE ONLY !!!
I never intended it to be gospel, nor expected anyone to take it as such. It's just a few facts a picked up here and there, then mashed them up to create one big factoid. As bruce pointed out, it merrily dismisses way too many subtle factors to be truly accurate.

Let's just say I got the urge to brush up my mad spreadsheet skillz, and call it day, shall we? I apologize for drifting off topic, which is posting OpenMM 5.1 FAHBench results instead of speculating (too much) on them.

Napoleon,
There was no intention to criticise your spreadsheet, I just wanted to know where the factor was coming from.

Updated the first post with Veix's information.

7im, are those results Single Precision or Double Precision?

GT430 is DP capable, but it's so very, very, very slow:

Oops, didn't see that option. Here are the DP cuda numbers, after about 10% each... GT 430 again.

Explicit Solvent DP: 0.9343 ns/day
Implicit Solvent DP: 1.72 ns/day

I know there's already 780 results from Anandtech's review, but I figured I'd share mine anyway:

GTX 780 SC (967 MHz core that boosted to 1124 MHz during the FAHBench run, 3005 MHz memory)

ASUS GTX 760 2GB (GTX760-DC2OC-2GD5) stock settings: 1006 mhz (versus stock 980mhz), 6000mhz VRAM

In FAHBench it boosts to 1175mhz. Completed a live WU without error yesterday although the car squeals, like every single GPU I've tested with FAH in the last 4 years or so. Anandtech shows the Explicit single/double at 29.3 & 4.5 which is roughly the same as my results:

Explicit single: 30.09
Explicit double: 4.57
Implicit single: 115.32
Implicit double: 6.18

Like everyone has said, it's in the same ballpark as the GTX 660 Ti.
