This! 

While the new Ryzens are indisputably strong, they are still hamstrung with the OC limitation that has plagued AMD for decades.  Since this is a flightsim forum, we anxiously await any Zen 3700x/3900x owner showing us how their new CPU performs at 5.0GHz all cores.  We'll just wait... surely someone will be able to get their Zen2 up to 5.0GHz all cores...  surely...

Two things:
1. Your core voltage on your linked picture showing CPU-Z is missing.
2. Your core voltage from your CPU-Z benchmark signature, set at 5.6Ghz is 1.536v at only 64°C.

You must be running an impressive cooling setup on a renowned hot chip (delidded?) that reviewers on YouTube would make videos of.

For us mere mortals, your test results are irrelevant, as most of us only have good air / AIO water coolers.

1. Cpuz XOC

2. Thats on my OLD 8700K , only for fun it need that voltage for 5.6ghz (not stable) its a 5.3ghz chip it worked at 5.4ghz htoff at 1.42v , 64C its only a minor load when cpuz validating.

End of questions you seems not belive this benches

So.....no test in P3D?  I wonder why.

Maybe because they are not generally available yet.

[pgde 571]

Westman -- there is a firmware bug that has been identified concerning OC'ing the new Ryzens. A driver/firmware fix is expected in a few days.

A firmware update is not going to solve the heat problem you can try and push it to 5ghz but I would have a CO2 extinguisher handy

Who cares! 5.0GHZ is only needed on low rez monitors or dated programs like P3d/FSX.

No reviews have identified a heat problem with the new Ryzens. Where did you see this? I have looked at Guru3D, Gamers Nexus and jayztwocents and all have said that AMD has finally addressed the heat issue and they run cooler than a 9900K.

[pgde 571]

And, clock speed is not the only determinant -- note the following IPC test -- https://www.guru3d.com/articles_pages/amd_ryzen_7_3700x_ryzen_9_3900x_review,9.html

The difference between a 9900k and 3900 is only about 5%. Much of that may be due to driver/firmware immaturity.

It will be interesting to see how P3D performs since all benchies that I have seen comparing single core performance indicates that the 9900K is only about 5% or less faster.

They won't do 5ghz. Der8auer said he was only sometimes able to achieve 5ghz on liquid nitrogen. Don't expect more than 4.4-4.5ghz manually overclocked on the new Ryzen chips.

 

Also in response to some others - posting Cinebench scores is absolutely pointless for flight sim comparisons. it's a highly multithreaded workload that tells you almost nothing about how it will perform in P3D and X-Plane.

Also, Ryzen chips lose performance in single-threaded workloads very quickly as you move down the lineup, whereas the Intel chips maintain about the same single-threaded performance. The 9600K, 9700K, and 9900K will perform identically in P3D and X-Plane, and most other games.

You're on a flight simulation forum so... this is the place where people care! 😛

I know it's testing XP11 and this is a P3D thread, it does give a guide to sim performance.

Thanks to @filou for bringing this to our attention over on Orbx's forums.

In line with other gaming benchmarks, the 3700X is down 6% - 14% and the 3900X is down 8% - 17% on the best Intel chips.
Clock speed advantage on single thread-dependent programs is still giving a performance lead to Intel.

As I'm on a Zen 1st gen CPU, I could see a 31% (or 11 FPS) boost from going to a 3700X for £319.
To go better than that would cost me at least an extra £60 for the CPU plus another £160 for a motherboard change. So an extra £220 to change to Intel (£540 total).

The take away from this is: If you're on any of the 8700K, 9600K, 9700K or 9900K Intel CPUs already, stay where you are.
The gain is only justifiable if you're looking at moving from an I9-7xxx series to a 9700K or 9900K, or a 1000 series to a 3000 series Ryzen.

Thanks for the Link

all intel I9 x299 have the same IPC at equal FRQ in this tests the difference is the all core boost clock

the same on 8700k to 9900k .

all I9 x299 Overclock to the 8700 std range and with Htoff in the 9900k std frq span for them overclocked 50-55fps in XP11 

8700k,9600k,9700k,9900K  at 5.0-5.3ghz depending quality of the chip and cooling and how much you feel comfortable to push the cpu 57-60fps

amd 3700-3900 have a very good ipc if you do the mesurements at same FRQ but lack of OC holding them back , hope they sort it out.

I am on 2 minds about this. Intel chips overlcock according to factory documentation to 5ghz. 600mhz higer then the AMD's. Cool sorted.

But you cant then go quoting 5.3ghz and call that a solid number if its up to the silicone lottery and how far you're wiling to push your CPU past factory specs.

Also, these chips haven't been on the market for even a week. Their still getting updates & fixes. And the new Ryzen master overclocking , alows you to share settings with other people, given time to mature, I am sure we can get better overclocking results.

That being said, I am not going to overclock, having a 3 hour P3d flight ruined because of overheating, or my radiator fans screaming for hours for 4 extra fps is not worth it. If that your thing, enjoy by all means, but I prefer stable, reliable and quiet.

Intel 9900k all core boost is 4,7ghz , 5.0ghz thats on single tread app , not in the sim

have you read the Intel factory specs or only locked at max single core boost like amd 4.6 or was it 4.7ghz thats correct 5.0ghz

Iam very impressed of the IPC AMD have manged, clock for clock wise cross my fingers that they can mange 4.8 all cores soon
