Hi,

 

For my "new" Unraid server I have the choice between the following CPUs / Hardware: 

 

i7-4790 in a Dell Precicion T1700

i5-7500 in a Dell Optiplex 3050

 

The i7 comes with hyper threading (8 vs 4 cores), the i5 is much more newer and supports a higher ram speed.

I am using no classic VMs, but Docker containers (about 15).

 

Which CPU would you prefer and why?

Depends...

Both CPUs are very old - but i would take the "more cores CPU" 👍

RAM-Speed is not relevant on Intel-CPUs and it doesn't matter for unraid...

But that's just my opinion

Just one thing to mention:

The i5 has a modern iGPU - this makes HW-Transcoding for Plex much more powerfull.

So in this case i would take the i5, if HW-transcoding is a thing for you.

good point, currently I don't need HW transcoding, maybe in future... I will keep that in mind.

Thats very important - take the advantage of this "more powerfull" iGPU.

The iGPU on the i7 is way to old and doesn't have a good quality compared with the HD630 from the i5.

The question is now, what is more important - CPU-power or iGPU-power

I think this could even help when using nextcloud and its "preview generation" for videos/photos (which I am already using). The longer I think about it the more I tend towards the i5

I'd take the newer processor.

In addition to the much faster RAM and newer GPU, it's also cooler running and more efficient (14 nm vs the older 22 nm lithography)
