CPU upgrade thoughts for my girls and crunching machines....

[phill]

I'm curious what you all think I should do... I'm in two minds at the moment,

1. Get all the latest the boards can handle (They are X370 and X470 Crosshair Hero's, 6 and 7...)
2. Just upgrade my crunching machines and put the 3900X's from them in my girls machines... (which has currently a Ryzen 2700 and a 2700X in)

So the question is really, what CPU would you replace a 3900X with? A 5900X? If I was doing that for all of them, that might be a little over kill, even for me as my girls machines barely game or push anything much, so I was toying with a pair of 5800X's... I did look at the X3D model, but that's another £100 on top and I don't think they need it or they'd notice it... (They each have a RTX 3070 card..)

I've seen the 5800X's for about £180 new but I'm looking at sales currently just to see what is going for the best bank for buck and such.. The reason for the 5900X would be the core count and since most of the machines in my home (aside from laptop and micro desktop) crunch, I'm looking at price/performance more so...

So, what would anyone do??.... I'm tried to come up with a poll as well that's not daft, but it's me and well, I think that's just all I am

Why upgrade at all then?

Why upgrade at all then?

Crunching mainly I think, more efficiency and so on. If I wondered it would be better to just grab two CPUs, I can upgrade my crunchers and then put the 3900X's in the girls rigs, I think that's a pretty good option...

Some Xeons sip power while having good crunch times. 2698v4 pulls 130-150w on 100% with 40 threads, however 5950x at 220w will take on two.

I think in my Dell R730s I have the E5-2684 V4 CPUs? Idle wattage for the server (each) is 290 to 300w... Put it under a load, 450w then... It's crazy. My Threadripper 3970X takes about 400 to 450w over 64 threads and I'm sure is twice the performance of the two Xeon's at the same power consumption....

The girls I don't think really need 5950's however nice it would be for my daily scores when I have enough solar power to run them all for free or if the electric is cheap or free, but the CPUs still aren't that cheap to buy either The problems with having multiple systems, its a bit costy lol

Get a 5800X and a 5800X3D. Make one of them gaming beast and the other value one.
5900X? No.
5950X only if they really need cores for whatever reason.

 

[phill]

I did wonder about the X3D CPUs but I wonder if the girls would be fine with a 3900X for the moment upgrading from the 2700 and 2700X they have in their rigs at the moment... Buy 1 CPU isn't so much a problem, but when I would like to buy 4... Price gets a little more erm, concerning

If your doing workloads the CPU can only do, spend the cash and get whatever gives the highest perf. That is unless you need the thread count instead.

 

[Toothless]

5950x chips with PBO off/auto sips power and still gives good clocks with all 32 threads. If you can find sales those would be best. Like 150w max.

 

[lexluthermiester]

My vote was Other.

For gaming, the 5800X3D is the CPU to have. It simply the all around best value. The 5800X is also very solid and not expensive. Either of those CPUs will last several years for gaming type tasks.

For crunching however, you should consider a ThreadRipper or at least a 5950X/7950X. These are greatly batter at compute tasks.

So the question is really, what CPU would you replace a 3900X with?

I personally wouldn't. That would work fine for gaming. If you've already got it, use it!

My Threadripper 3970X takes about 400 to 450w over 64 threads and I'm sure is twice the performance of the two Xeon's at the same power consumption....

This! Since you already have it use it for compute tasks!

Voted 5800X3D (or 5950X), the 5900X isn't worth it IMO. With the latest AGESA, the C6H is a solid board, give that thing a treat, cheers

 

[freeagent]

I vote 5900X because I have one, and a 58X3D.

 

[phill]

Thanks all for the great advice and options I've made a choice, saw something, shouldn't have bought it and got stuff on the way

For reference, I've the following CPUs....

2 x 1700X
1 x 2700
1 x 2700X
2 x 3900X
1 x 3950X
1 x 5950X
1 x 2950X
1 x 3970X

Now I've not included the Intel CPUs that I have (some in servers as well that I use to crunch on) but after reading your comments I've gone the way that I think won't be the optimum in gaming performance but believe me when I say, my girls don't get close to games actually needing a 1700X at the moment.... What my plans are for the moment, is to swap the 1700X for what I've bought, put the 2 3900X's (from the two Crunching machines) in replacement of my girls two CPUs (the 2700 and 2700X) and then use the newer CPUs in the crunching machines as I figure that the efficiency/IPC/performance etc. would be better off with the crunchers than my girls machines... They don't really get used much but the crunching machines get used every day with the RTX 3080 they each have I do crunch on my girls machines but I feel the step up from what they currently have to the 3900X's, it will be a decent step up and will net me some nice Brucey bonuses when I get some sun and can run them altogether Can't wait to show you all my choices but thank you all for the help and advice

I vote the 5900X, especially since Amazon has them for under $300 for Cyber Monday. I have one myself.

 

[AusWolf]

Do the girls game? If so, a 5800X3D is a no-brainer. If barely, then a 5800X is a cheap but good upgrade. If not at all, then why upgrade?

For crunching/BOINC, I tend to look for lower power consumption, not efficiency. WUs get completed on time either way, but with a lower power bill.

Just my two cents.

2. Just upgrade my crunching machines and put the 3900X's from them in my girls machines... (which has currently a Ryzen 2700 and a 2700X in)

I would do this with the 3900X's and just go with the 5800X's in your crunching rig.

 

[An0maly_76]

I vote 5900X because I have one, and a 58X3D.

So which one are you using THIS week?

 

[Deleted member 229121]

If you're not gaming skip the X3D - ball out with a 5900X or save yourself a few bucks and go 5700X.

 

[freeagent]

X3D

 

[P4-630]

If you're up for a challenge, try something different..... I present you the Chinese threadripper...

 

[A Computer Guy]

I choose other. This question may be blasphemy but are e-cores good for crunching? They've got to be good for something right?

 

[Bobaganoosh]

I'd vote 5900X or 5950X. You already said gaming isn't the main target so I'd skip the X3D. I'd also skip the 5800X. It's a good CPU, but it's hot. It's often hotter than the larger chips because it has more power per CCD. The 5900X and 5950X spread the heat to two CCDs, which gives more surface area to dissipate heat and they thus are easier to cool. I've known multiple people who had to use over-powered aio's to cool their 5800X even though it's such a low power chip just because it can't get the heat out of such a small area.

I don't do crunching, but used to F@H, and I'm assuming you're going to just run them at max power (and heat), so that's what I based my answer on: getting the most out of that power/heat.

Which isn't to say the 5900X doesn't pose its own cooling challenges. However, mine hovers around 72C under gaming loads, idles around 34-39C. I have a huge tower air cooler in a decent case with six 120mm fans though.

Which brings another consideration to bear. Does the case have enough airflow for a 12-core?

I first cooled my 5900X with a Noctua NH-U9S because the cooler I had and was going to use (can't remember what it was now) was too tall to allow me to use my 200mm fan at the top of my CM HAF XB Evo case. I needed something and it worked, but heavy loads were low 90s (when transcoding) and low 70s when gaming on a cooler not designed to handle that much. The point to my little story is that you don't need a big air cooler, but you need something better than the little NH-U9S and temps should be good.

My case just has the intake fans pushing cool air through the rad and then the rear 120mm and top 200mm exhaust.

A short while later when funds were available I moved to a H100i AIO and temps sit around mid 70s when I'm transcoding and idles at 31C.

Buy 5600(X) for everyone, and only think about 5800 series and higher stuff if you can't wait for 5700X3D/5500X3D release next year.
