Worth upgrading from i7-940 to i7-4770

[venture996]

I have 7 cameras, a total of 16mp of video. Currently run BI4 on an old i7-940 and while it runs great (stays at 10-20% CPU), I know its an energy hog. I can get a free i7-4770 with 8gb of memory (getting retired in my office). I think this would support H264 decoding on the motherboard, and I believe it would be a lot more energy efficient. Any opinions on this based on experience??

yes...you are tossing money down the toilet by using the old 940

Thank you, took all of 2 minutes and I received a definite answer. Much appreciated. I supposed I should order a WD Purple drive to hold the clips.

You should be okay with the standard drive that is in there... But if you're installing a larger Drive definitely go with the purple...

I was just looking at WD purple drives, and Amazon sells a new gen ($50) and old gen drive ($62). Anyone know the difference?

i have had a purple drive for less then a year.
Server been off for a few months.
Used the disk only for recordings not more, and it suddenly broke down.
Got a warranty disk in return but who knows when it will break down.

been years ago that i have had a broken disk.

yes, very large sample size you have there...posts like this are useless.

$12......sorry, I couldn't resist!

I don't know the real diff, both surveillance-rated (high duty cycle, high-write workloads, lower power & more) , same cache size, same warranty. You'd have to study specs sheets side by side, I guess.

Probably not worth wasting time on, both are WD and are Purple...I'd go 'new' and enjoy a Blue Moon 12-pack or a 8 oz. top sirloin with the savings.

Ok, thanks for the help. I'll move the system over in a few weeks, while I'm enjoying my beers.

Better optimization. Buy the new one.

So I made the switch today, it was very easy. IdI estimate I'm saving 125 Watts of power. Turns out the boot drive is an SSD, so I used the original 1tb sata drive for clip storage. And I found an nvidia video card in there too, which I pulled out. Even setup remote desktop so I'm running headless now.

Only thing I haven't tested yet is the 264 hardware decoding. CPU isn't very busy, so I'm in no rush.
