Hi all! It has been a while and my output is low due to heat in my area. I wish I could crunch year round but energy costs and heat are keeping me from doing this in the summer. I wanted to ask, in your opinion, what is the most efficient and cool running crunching processor you know of?

My baseline is two PowerEdge r610 servers, fully populated with old xeons. I am looking to replace those with one efficient cruncher (single processor). My ppd will be lower by consolidating but it is better than dealing with those beasts!

A real low power/high yield solution is a 1800 in a decent x470 board running Linux. You know this thread of course. This leave you with plenty off options to upgrade to at least twice the output provided you can keep the VRMs cool.

I'll put my +1 for undervolted Ryzen 7 1700 or 1800. The only other power-efficient alternative may be Xeon D-1541, but those embedded boards are super-expensive and will definitely be slower than Ryzen.

Power efficiency of Zen 2 is good, definitely improved over previous generations, probably due to the 7 nanometer production process. What caught our attention was multi-threaded energy usage, which measures how much total energy is used to complete a specific task—it takes into account not only power draw, but also time required to complete an operation. Here, the Ryzen 9 3900X claims the top spot as the most energy-efficient processor we have ever tested. Temperatures are a bit high, though, with 79°C, but all the performance has to come from somewhere.
Just say'n. Also, Intel "T" processors are really good as well.

I've always wanted to see some numbers from the Xeon-D's.

Multi-threaded performance is crazy, considering it's a 45W part. On passmark it's listed at only 20% slower than Ryzen 7 1700. I've always wanted one(even now when it's a bit outdated), but the price is still steep. I think now it may be cheaper to build an entire Ryzen 9 rig, than getting a D1541 board alone (both Supermicro and Asrock variants are priced at ~$1000 or so)

I've only got my 6700k plodding along @ 4.0ghz 1.2v atm (seems weird to me setting vcore to less than 1.4v! :laugh:), an undervolted ryzen would definitely be more efficient but this isn't too bad at 65w package/55w cores. 52c average. I still have to stop it on the really hot days, not because the hardware is hot but because I am! lol

Sorry for abandoning this thread. I've been quite busy. I was thinking ryzen was the way to go. I also don't want to break the bank so that is another plus. I am certainly not married to a manufacturer so I will look into the 1700 or the 1800. Thanks for the tips!

EDIT: Speccing out a 1700 on pcpartpicker. Any power supply recommendations? I would like it to be somewhat efficient. Also, for a 24/7 cruncher any cooler suggestions?
EDIT2: https://pcpartpicker.com/list/MwQxnH hopefully no egregious errors here but this is what I was thinking.

That would be an amazing crunching rig in terms of power efficiency and value. Personally I'd try to step up to a B350 board for a bit more control over clocks, but can't really argue with a $60 A320. Should be able to handle a 1700 with a downdraft cooler. And I was going to suggest going for a lower wattage psu, but looking at the price you might as well go with what you have.

I think when I upgrade my main rig to a 3700x or 3800x I'll move my 1800x to my HTPC and let it crunch away at say 3.3ghz 1.0v 24/7, I wonder if i could get it away with a passively air cooled setup hmmm.

@infrared I think I may take your suggestion on the board because I will most likely be buying the 1700 used. I may take a whack at putting up a WTB in the proper section to see if I have any bites when I am ready. If not, there are plenty of fleabay listings with good ratings. If there is a reason I should not do this, please let me know. I agree with the PSU statement that it is a bit OP but a good price.

I'm so slow....
The A300 motherboards will not support the 3xxx series of processors. I'd suggest something in the B450 range such as ASRock B450 PRO4 for $5 more after MIR. Deal ends Thursday

If this is a dedicated crunching box, a 750 watt PSU is WAY too much. My 1700 pulls 131 watts from the wall with a gold rated 450 watt PSU.

$270 for a 1700 is nuts (they're most likely running out of stock and the price is actually going up). Newegg has the 2700 for $201, and that comes with a cooler - therefore $110 cheaper. If you want a cooler that will be quieter than that, the Scythe FUMA (there's the Rev B and the newer version 2) does a great job at a great price. The fan in the middle of the FUMA sits so low that it blows air at the VRM's.

As I found out the hard way recently, you'll need more than 8 GB of RAM for a 16 threaded system. 16 GB should be fine, and I'd look at DDR4-3000 or 3200. As always with Ryzen, make sure the RAM is on the motherboard QVL list.

To me, the problem with a "too large" PSU is that the low loads that you'd be dealing with put the PSU in it's lowest efficiency range. Then I looked at prices. I forgot, when something new is introduced to the market, PSU prices always go up. I'm always looking for deals that are about $0.10 per watt, normally after a MIR. On July 3rd, I posted in Hot Buys that the Seasonic FOCUS Plus Series SSR-550FX 550W could be had for $52 after a $25 MIR. Now it's $96! (I actually like semi-modular PSU's for this application)

You'll need some sort of video card, at least to set it up. You can always set it up to remote in later.

@thebluebumblebee That is a good point about the PSU. I will downsize to 450 gold. I am also going to bump up the RAM to 16 as suggested and if my A+ training taught me anything, I will check the compatibility list lmao. I am seeing some good deals on the b450 boards too so no problem there. This may be a few weeks off at least, but I am getting more and more serious about it. I should probably invest in a kill-a-watt too just to see how inefficient some things are in my house lmao

This chart is so interesting for what we do.



Which brought about this statement:
Power efficiency of Zen 2 is good, definitely improved over previous generations, probably due to the 7 nanometer production process. What caught our attention was multi-threaded energy usage, which measures how much total energy is used to complete a specific task—it takes into account not only power draw, but also the time required to complete an operation. Here, Ryzen 7 3700X claims the top spot as the most energy efficient processor we have ever tested.
So, the 3700X is more efficient than the 2700 which is in turn more efficient than the 1700 (had to dig for that last one) Of course, $330>$200>~$100 :laugh: (The 3700X at $330 would be a no brainer against a 1700 at $270)
Also, you have to be careful with out of the box support for the 3000 series CPU's for 300 and 400 series motherboards.
