Today I became my AMD 9900X3D combined with my excisting 4090 RTX on my excisting 670e Aorus Mainboard.

PBO activated Positive 200MhZ

SMT ON

SVM OFF

Curve optimized just quick and dirty for the time being with negative 20 at all cores 

Driver puts the SIM on CCD0 wich has the X3D Cache, NO optimized OC at the moment. 

32 Inch 4K screen or

Varjo Aero 4K resolution as well

All testing with DLSS Quality

-----------------------------------------------------------------------------

MSFS2024

My testcenario is inibuilds OMDB GATE F20

Clear skies

iniBuilds A350 Engines running all systems on

TLOD 150

OLOD 150

Everything at Ultra raytracing on

DLSS Quality mode

FrameGen OFF

AI Traffic all OFF

7900X3D - 50 FPS

9900X3D - 60 FPS BUT BUTTERSMOOTH at panning and taxiing. After takeoff quikly 75 FPS

+10 FPS

Turning FSLTL on with roughly 80 injected planes does nothing to this chip in MSFS2024

With TLOD 75 at ground via DynamicLod I get 70 FPS. While flying around Dubai with TLOD 150 my FPS is between 70 and 75

With TLOD 75 at ground via DynamicLod I get 85 - 90 FPS. While flying around Dubai with TLOD 200 my FPS is between 70 and 75

In VR:

Flying in EUROPE is smooth again and EUROPE, especially above Germany, was a bigger stutterfest with my 7900 X3D and TLOD200, now with 9900X3D scenery loading is smooth and I can maintain 45 - 50 FPS in VR with FENIX A321, TLOD 200 and everything on High in MSFS, FSLTL ON. At EDDF I could maintain 45 FPS in VR )Varjo Aero, running 4k resolution and 60 injected AI planes via FSLTL-

-------------------------------------------------------------------------------------------

This Chip runs on the same temperatures at my and (Watercooled 60 - 70 Celsius in a 20 Celsius room)

Both sims run much more smooth, most noticable uplift in FPS and Lower Frametimes in MSFS2020. MSFS2024 has its smaller LOD loading issues when approaching heavy scenery airports (like inibuilds EGLL and OMDB are). But still the performancegain is noticeable FPS and frametimeswise. 

In VR my FPS are lower then on 2D but I can maintain 45 FPS at least in both sims when using Auto FPS with TLOD Base 75 and 200 at 2500 Feet upwards without any issues.

For me the Chip is a huge upgrade, allthough the price EUR 670 is very high. For me it was worth it, but that is just my opinion and my passion I think. 😉 

 

I need to test different BIOS settings as well. This new CCD management has also some new BIOS entries like LOW Latency modes etc. I haven´t tried them out yet.

Marcus

Thank you very much for your summary Marcus.

I look forward to any future comments you have regarding this CPU.

I currently have the 7800X3D and are thinking about an upgrade. FPS is not that important to me but smoothness is.

Does this CPU have a dual chiplet architecture?

Something is not right about getting 60 -65. I have an ultra with only TLOAD 200 and OLAD 150 locked at a steady 90 FPS.

Looked at price on Amazon, close to $900.00 and only 2 left in stack.

At 4K? Unlikely.

Yes, 4 K indeed. Something is missing in there. Also -20 on curve. Another important factor could be the power settings in Windows; please check this, even if it's 9950x3d

You have to check and see if the 3D is turned on. Core parking is not automatically activated unless you install as a fresh copy of windows. If not you must turn on in BIOS along with an updated version of AMD adrenalin software. If you go to the task manager, you should see it running under the process tab. I got one hell of a video boost when I activated core parking

Yes CCD 0 and CCD1. But the CCD0 Chip Cores are Overclockable. With Curve optimizer set to negatives it hits easily 5.7 GhZ on the Cache Cores, wich are all the 12 cores. So you are able to get this 128 L3 (2x64 MB) cache AND high clock speeds.

My 7900X3D had 64 MB cache on the second CCD chiplet, called CCD1, and flightsim but there was no cache on that chiplet. Now, with 2x64 MB cache spreaded over 2 Chiplet, CCD0 and CCD1, you always use cache cores and are able to use high clock speeds.

Hmmmm...I need to check things then. Thanks for the headsup

Framegen off? 

Its possible most likely that I tested this with the CPU heavy IniBuilds a350,wich is very heavy on the FPS when switching to outside views. 

Every other plane has higher outside FPS compared to cockpit FPS, Not the A350. 

I will test it with asobos Boeing 737max.

Core parking is active. I checked that with the 7900x3d already but will recheck it. Via the resource monitor I see the 6 parked cores when MSFS is in focus on the first 6 cores. 

What have you actived in the Bios at the CPPC (dynamic preferred cores) setting? Driver, Cache or Auto?

I don't believe you need to do a fresh install of windows, especially if you're coming from another X3D CPU. IF the AMD 3D V-Cache Performance Optimizer Service service is running, the software is doing its job.

CPPC dynamic preferred cores is set in my bios to "driver".....in the resource monitor I see the parked cores when switching from msfs to Ressource monitor quickly.....

And my powerplan windows is set to balanced.

That services (2x services wich named almost equally) are running.
