Is there an accepted rule, like a "passmark/camera" ratio, that you should strive for? I am considering used i7 laptops to run BI, and would like to know if they have enough crunching power. I understand they are more expensive than equivalent refurb desktops, but I find the low power consumption and integrated screen attractive.

Laptop is a poor choice... Modern desktops are very efficient, idling at 16 Watts and using between 30 and 50 Watts depending on your load..

Ok thanks. My wife is running an Optiplex 9020 i7-4770 SFF right now, I can plug it in the power meter and see what it really draws. Once I drill out the side panel to help the cooling, maybe she gets an upgrade ☺.

Should be fine as long as it has 8GB RAM. Unless it's a newer generation, most laptop i7's will only be dual core however.

With that said I currently run 7*8MP cameras on a second gen i7 (and host a couple of VMs on the same box), I had to upgrade to 16GB RAM in order to fit everything in. Admittedly, this is a desktop, albeit an old one -- Dell 790.

I average 60-70% CPU consumption and around 14GB RAM utilised (3GB of which is VMs).
 
Well I placed the Optiplex on the killawatt, no screen, 170 watts. Now there is a 66w Radeon 8570 gpu on there, but still at exactly 27% cpu utilization, that's still 100+ watts. A bit more than I want to consume on a continuous basis.

Its your card. They are very inefficient. These modern systems draw 16w at idle to about 80-100w maxed at 100 percent cpu. There are many threads discussing tested power usage, you will see that your numbers are way off because of your card.
 
So you re saying that it consumes more than the TDP rating of 66w? Once it becomes free for use I'll pull the card and check again. The only other thing I have in there is a sata and ssd drive. IIRC these don't amount to much. I'll even pull the DVD drive if i have to :)

yes, or your power supply is defective or very inefficient. The other possibility is that you didnt measure accurately or properly.
