Is there really any benefit in terms of power consumption at idle from the Sandy Bridge / Ivy bridge line to say the Haswell/skylake line? Looking at an I3 or low end E3 for a possible NAS project that will be sitting idle most of the time.
Hi T_Minus,Funny this comes up now... I'm working on a couple low powered nAS and desktop systems based on E3 v2, E3 v3, and both generations of the i3.
I don't think I have any SandyBridge CPUs left (e3/i3) to compare to, but they're tempting with what you can get them for... although I've seen the V2 1270s and 1280s under 200$ which I think is the SWEET spot for $/perf if you need high freq. / single core perf. I settled on the E3-1230 V2 for under $130, and I have a handful of i3s as well as the SUPER LOW E3-1220L V2 (my favorite E3 ever really) for the v3 I have a E3-1231 V3 in my test bench.
I'll let you know power #s when I build the V2 system today, and boot the v3 as it's already my bench complete system right now.
I wish v1 idled lower and/or we could get the E3-1220L V2 for <$100!
Is there really a difference in the idle usage of the L vs Non L CPUs? I thought the L ones were gimped on the high side to maintain the power envelope low.I have a stack of 1U ready to deploy, haven't done them yet... v2, and v3.
I did just finish swapping my home AIO to a E3-1271 V3 which will be down graded to a E3-1265L V3 I've mentioned in the "Great Deal" area a few weeks ago.
I'll post power numbers when I get it running again, just a couple software things left to finish... I know it will save power over the E5-2670 V3 it's replacing LOL!!
At least from my experience nothing in it, as you say gimped to now exceed maximum TDP to keep power and heat in check. I would only use them when constrained in heat generally.Is there really a difference in the idle usage of the L vs Non L CPUs?

How do you connect those anyway? Power Brick and matching adapter cable? Never figured that out - never looked very hard either to be honestIn theory even better than the pico psu would be the boards that take 12v (or other voltages) directly. SM has some sever boards like this (eg x10srm)
Arent those cables same as the the one used in the supermicro SYS200 AND SYS300 superservers?those are available retail.@Rand__ you just have to make up a cable really, can’t be that hard although I have not done that specific cable before... may tell you shortly as I was thinking to do one soon, just a little fustrating that those boards only has 4 dimm vs the scalable version that’s 6 dimm so 50% more ram but e5 v4 cpu’s are cheaper and more plentiful.
