CPU Upgrade Advice.

[Alpine Scenery 1,609]

It will run faster if you upgrade the CPU since you are on a 3090, but how much faster will vary depending on your addons installed, the plane you are flying, etc...
This is because the addons themselves cause a slight change in CPU-GPU allocation balancing, as well as other things.
People tend to apply their setup and assume everyone is the same, but everyone plays the game differently with different addons, etc...

So it would be hard to say if you can get a reliable 20%+ increase by changing your CPU. 10% gain is easier, but upgrading the CPU might help with stutters regardless.

FPS is not the same as stutter-free though, I mean I can get 40+ fps and still have an occasional stutter. The higher the FPS the more power you have overall, the less chance of stutters, but it's not a direct proportional relationship. The FPS-Low number is slightly more tied into number of stutters, but even this is only an indicator of overall performance lag, not an absolute 1:1 relationship.

Brute force has value for sure for stuttering but it's neither necessary, nor fully effective, in eliminating all stutters/microstutters/pauses/etc. 

I believe many who are enamored w/ 60+ FPS are really seeing reduction in perception of subtle stutters thru brute force.  It breaks thru and still nails them though in the right scenarios, even though in between it's Nirvana.  My biggest detriment by far, are the presence of stutters of any kind.  Rock solid stutter-free 30FPS is shockingly fluid and I have it after a lot of experimentation and troubleshooting.   I'd love to be able to share what I see now w/ those not quite there.

I also believe now having gotten there in spades that it is very possible to have virtual complete elimination of all stutters in all phases of flight, and is true for me now even in the PMDG 738 at FT's KLAS and over KLAX.  The exceptions now for me are having T-LOD too high for what my 9900K/3080Ti can cope with so I have to be judicious with that.  But that's just flat out no big deal, visually.   This is where that new CPU *should* handily solve this shortcoming for me, and for me it's around +40% increase in single-threaded performance.   With Howard's 3090 it should be a little easier still to get there even at +20%.

I run a fairly hefty machine based on 32Gb RAM and a RTX3090. However, I think my week point is likely to be the I7-10700 which is boosted to 4.8Ghz. My question is, can anyone offer some first hand experience of upgrading from this processor to an I9, and if so , which version would see a worthwhile gain in performance for me? I am conscious if I am running at 4.8Ghz whether I can actually find a boost in performance by upgrading to an I9 (not sure which model) If so, can I get to 5.2Ghz without a big overclock? Help with this will be appreciated. Thanks guys.

you may have good luck over on the hardware forum here at AVSIM

Well if its a gain in performance you are after I'll offer you an out of the ball park suggestion. I see you use a 4K monitor. I'm going to suggest if you don't already have one to beg for, borrow or steel an NU6900 Samsung 4KTV and try MSFS and P3D at 24 and 30hz on it. The reason I say this is that this model number (and many other 4KTV's) have what is commonly known as a Judder Reduction filter which is controlled via the TV's on screen menu with the remote. When it is activated the TV interpolates a frame between each frame delivered by the graphics card. So, When you are setup for 24hz with vsync on instead of seeing 24fps on your display you will see 48. 24 generated by your system and another 24 generated by the Tv's hardward. Likewise for 30hz you get 60fps on screen. Its sounds remarkable and it is. But my suggestion is always try this before spending a bundle on hardware. Samsung 4KTV's are pretty ubiquitous. You probably have one in your own home or have a friend or relative who has one. It's an odd question. 'Can I borrow your TV?"🤪 but I bear wittness to the fact that it works extremely well. I have all the setting in MSFS more or less maxed out and most of the time I can maintain my FPS over 30fps but for me that's 60fps and when I cannot maintain 30fps (one the ground at big international airports in a 737 or an A320) I can maintain 24fps but for me that's 48fps. It sounds a bit like DLSS and it is. It does take a little tweaking to get the best results but I'd certainly suggest that anyone thinking of a $$$$$ upgrade owes themselves try it first. Its like playing Flight Sim hardware that doesn't exist yet.🤣 Anyone who has been around FS for long enough will get that joke. 😁

" L3 cache obviously reigns supreme here as the Ryzen 7 5800X3D is an incredible 20% faster than the Core i9-13900K. Here we see some odd performance trends with Ryzen 7000 processors once again, with the Ryzen 9 7900X inexplicably trailing the other chips regardless of how many times we retested. This suggests some game code tuning could be in order. "

Ryzen 7 5800X3D is the M4 socket. Newer AMD cpus will need the new M5 socket motherboards. And newer RAM. I would get a cheap B450A motherboard (M4), Ryzen 7 5800X3D, keep my present RAM, and save $1000.

Is AM4 x570S not a better option?

[Fielder 3,804]

I wouldn't care about PCIe 4.0 but 2 USB C slots is nice on this 570S for $200, might be a little better choice

If it were me I wouldn't spend the money going to an i9 on your existing board etc.  The gains will not justify the cost in my opinion.

If you just "gots to" upgrade now then as said AM4 (5800X3D) seems to be today's top dog.  However, that AM4 setup, just like today's top-line intel setup, is end of life.  AM5 comes out soon(tm) (to quote the inside joke from the PMDG forums).  But in seriousness, supposedly at or around the CES 2023 conference in January, the first of the AMD's AM5 hardware is supposed to be released, which could be just as good as the 5800X3D appears to be for us.  AM5 will be in place for several years.  During all of this, I don't expect Intel to stand idly by.

The Samsung TV thing just mentioned -- that's interesting.  Lately I've been wishing I had something that refreshed at a /higher/ rate than 60hz (in light of DLSS3) but going to opposite direction with Samsung's tech is interesting. 

New tech like DLSS3 and new hardware could be big for us because for years we wanted a lower refresh rate (like 30hz) as the hardware and software we used just couldn't maintain the framerate.  For smoothness we had to go for the low refresh rates.  Now today, we're seeing DLSS3 and better hardware and software, and suddenly we may actually benefit from high-refresh rate displays.  This tech is going to trickle down into average-level hardware over the next couple of years.

well ok I mean the 7800x3d then

[Alpine Scenery 1,609]

That is interesting, but I'm more interested in the AMD 7900xt GPU that will be announced on Thur - Nov 3rd.

I read it only has 20GB VRam instead of the original predicted 24GB, which is great because hopefully they'll reduce the price.
I might even be interested in a 7800xt depending on how it performs.

In all respects, the AMD 7900xt should beat the 6900xt by a sizeable margin, which means it's going to beat the 3080 TI / 3090 too, and it's going to cost a lot less hopefully.
Though rumors has it AMD might try to price at $1199, that sux if so. I really want it to be priced at $599, $799 max, then I'll bite and try one.

I think it's going to be a great card, but I don't think the price is going to be low enough to justify my cure for upgrade-itis.

Other testers shows the exact opposite!!

(Like Tomshardware etc.)

Also the 5800X3D is running DDR4 @3600. 

Pricewise 5800X3D still seems king for FS2020 

Here in Europe the 5800X3D is half the price compare to  the i9-13900K. 

Much expensive RAM and motherboard for the I9.  

I switched to the 5800X3D coming from a I7-10700K. 

Yes it's not the latest and the greatest (AM4)  but it can compete with the latest and the greatest!!

Bought second hand AM4 motherboard and new 5800X3D for les then 500 euro together  

RAM and cooler etc I could re-use. 

Only the i9 13 th on it's own is 760 euro here in Europe.  

New expensice ram and cooler and motherboard. 

The 5800X3D upgrade is a bargain

debated picking up the 5800x3d now or waiting for thr 7800x3d/7900x3d in q1. I decided to wait till q1 and upgrade to AM5 then when hopefully prices for motherboards will have also dropped a bit. going from a 5900 to a 5800x3d for me make no sense because everyday usage wise you are going backwards. I can wait 4 or 5 months for the latest and probably best performance. 

[Alpine Scenery 1,609]

Yah, 5800x3D + a new 7800xt or 7900xt would be the best bang for buck obviously.

Though any of this stuff will work, and some people aren't as price sensitive.
