Need advice on CPU upgrade

[JG_deserteagle540]

Dear,

 

Could somebody help me with some advice on my CPU upgrade please?

 

When I am playing off-line in QMB/AQMB and a lot of planes are selected the fps start to drop to 80 / 90 fps, because of CPU limitations.

So I am thinking about upgrading my CPU to an AMD 5800x or 5900x or a 5800X3D.

 

My currents specs are:

CPU: AMD ryzen 7 3800X
RAM: DDR4 32GB @ 3200MHz
GPU: RTX 2070 super
Game settings: High/Ultra
Playing: off-line 
Monitor: Alienware AW3418DW  WQHD 3440 x 1440p @ 120fps

A RTX 3080Ti is underway and will be installed soon so all game settings can be put on Ultra.

Which CPU would be great for playing off-line ?

 

Thanks in advance,
Mark

I'm close with a 3900X, 32 GB of PC3600, 3080 12GB on a 750W PSU. The PSU appears to be working OK ATM but I was worried it was at the edge for this card after bumping up from a 2060. I'd be looking at that to push the 3080Ti, maybe go at least 850W.

My power supply is a 850 Watts Cooler master Plus Platinum series. Should be enough I hope.

In gaming and Il-2 as well, from the CPU's you listed, the 5800X3D is the best performer. 

 

Check these in game results:

That extra cache of the 5800X3d makes a difference in game, compared to the regular Zen3 chips.

For non gaming applications the 5900x is a better buy.

More than enough I reckon.

 

In fact:

 

This is about the 3070, but I think most of us really are running way too powerful PSUs. My 550W Seasonic Focus+ FX Gold has no trouble with my rig (i5-12600k, RTX 3070) but would probably be deemed way underpowered if GPU manufacturers are to be believed.

@Jaws2002, so the difference between the 5800X and the 5800X3D for the 1080 test is about 10 fps and for the 4K test about 4fps.

 

Thanks for the advice.

I will buy the 5800X3D  CPU

As long as you have a high quality PSU (GOLD standard or better imo), you can get away with a lower rated PSU.
The cheaper ones can be very inefficient and cause brownouts under high load (esp when u run them harder for an extended time, and the really cheap ones don't even have a rating).
The main reason the say higher than you need it to cover these cheaper quality but higher rated PSU, because when pushing a psu nearer the limits the efficiency of the PSU matters a lot more. The harder you run the PSU the hotter it gets (lower efficiency means more waste heat, and cheaper quality componets are likely to fail in time)

Ideally you want to max load far lower than max rating of the PSU so it runs relatively cool and will last longer.

FYI: Your PSU is a GOLD standard one.

Rated PSU for the 3080TI is 750W, (850W platinum rated is more than enough , unless u are overclocking the CPU/GPU, massively)
That GPU draws about 350 watts under load(itself) and max load for a RTX 3070 is about 240 watts.

I'm running the 5800X, and a 3070, 64GB RAM - 750 watt PSU.

Running DCS and IL2 full-tilt-boogie...couldn't be happier.

I got tired a long time ago of arguing with people who think they need 1000 watt PSU's - 

[=RS=Stix_09]

Ya not many setups need more than 750W.

[BladeMeister]

One thing that can be said for running a higher watt PSU is that a PSU which runs the PC's, under load(gaming, benchmarking, video editing), constant watt usage closer to 50% of the PSU's total capacity for output insures that a PSU will run more efficient % wise and cooler, bear the constant load easier and handle any(albeit rare) wattage consumption spikes with ease. Most likely this same PSU will last longer although I have ever had only one PSU literally go bad and that was over 20 years ago and it was HEAVILY used for over 10 years. Just use a computer component assembly wattage calculator and then if you desire, depending on your wallet, go higher than the calculated need with a gold or higher efficiency rating. More power is not a prerequisite, but sufficient power is.

Oh yeah, no doubt about cheapo, ketchup-and-mustard type PSUs. The last pre-built PC I ever bought (back in late 2000) came with one of those and when I upgraded that thing's GPU the second time (Radeon 9700 to GF 260 IIRC), I managed to fry the PSU. Small wonder, really, since I just looked up the specs for that PC and it originally came with a GF 2 MX.. ?

... whose TDP is listed as "unknown" on techpowerup, but the 9700's was 37W while the 260's was a whopping 182W... lol. Damn, I was stupid back then...

 

 

I do have to wonder if that kind of ultra-cheap PSU is even still a thing 20 years later for gaming oriented setups.

I had a 1200W platinum power supply die on me and it took down my motherboard.. Now i "downgraded" to a 1000W Titanium??

What do you have that requires you to use  a 1200w PSU?

[Jaws2002]

I didn't need 1200W. About seven years ago my 860W PSU died. The only decent quality PSU that if found locally was a 1200W cooler master, so that's what i bought. 

When that one died, two years ago, I ordered a Corsair AX1000 to replace it. 

 

Power supplies work best at around half their max power. My 3080TI was sucking, alone, 450W before undervolt. Add to that a 360mm AIO, a 5950X, PCIe gen 4 drives, plus the rest of the stuff...I exceed 600W under load.

A bigger PSU can never hurt. Much better than the alternative--having too small a PSU. It's not like the thing DRAWS 1200W itself, it just has the ability to provide that much. I think that's something that's often times misunderstood. Always a good idea to have at least some overhead of capacity above what your projected draw might be. 1200W might be overkill but if that's what you could get at the time, it is what it is. You're fine.

Agree with that up to a point. If you look at the Power efficiency of power supplies, They are the most efficient and most reliable, somewhere around middle.  IF you have way too big PSU for the load, then it will work most of the time in the bad area of the efficiency curve.

 

This is my PSU:

We're talking about a difference in efficiency of a couple of percent-points. Here's my PSU's curve:

 

 

 

Even if my system would draw 95% of available power, I'd still be at 90+ % efficiency with this thing (I do use proper, 230V current ).

 

 

Doesn't make any sense IMO to go and buy a totally over-sized PSU, paying a hefty premium for it. Use a decent power calculator (preferably one that isn't maintained by a PSU manufacturer.. ) and if you need the added peace of mind, add 50W to its recommendation.
