Expectations for AMD8700G

[MadMonty]

I would like to upgrade the CPU of my current system (AMD 5800x + RTX4090). I've already realised that the AMD 7950X3D has no real advantages over the 7800X3D respectively that the price-performance ratio of the 7800 is significantly better.

But now I read that the new AMD 8700G CPU is due to be launched at the end of the month. There are no benchmarks yet. What is your expectation / opinion compared to the 7800? Will this be another noticeable step forwards, or is it just cosmetic?

PS: Of course, the upgrade also means a change of mainboard and RAM...

absolutely no expectations until GN post their reviews ... speculation is it will be faster ...

I would say it will be worse in gaming then 7800X3D.

I'd be shocked if it were even 15% faster than your 5800X.

You have a 4090.  I would avoid any G suffixed CPU.

AMD 8700G is an APU, worth it for those not going to use a dedicated GPU.
It does have very good performance if looking at the leaked benchmarks, and it does have a few interesting (non-gaming) new features, like the Ryzen AI neural processing unit (which accelerates AI workloads, for those in that field). 

But it's not something really worth upgrading to if the use case is gaming. Not (IMO) if coming from 5800X, and not for someone using an RTX4090 24GB (fastest GPU today).
In your case, you want a processor with 3D V-cache.
The 5800X3D can be an option if interested in remaining in AM4 platform, making a simple and direct CPU swap only.
Or the 7800X3D if thinking about upgrading platform, with AM5 (X670/B650) motherboard + DDR5 (6000 CL30) memory. More expensive but biggest boost in performance.

8700G will be slower due to higher TDP and lower PBO Headroom and no VCACHE.

as other have mentioned already, it's an APU with 1060ti level GPU on board, but throwing 2 full size processors on one substrate (CPU+GPU), especially when running sims like DCS, you'd hit thermal throttling significantly easily.

Thanks guys. After further research 

 

AMD 7800X3D

64 GB DDR5 6000 CL36

ASUS ROG STRIX B650E-F

 

is already on it´s way. Should be a hell of a system...

 

Hope that CL36 vs CL30 does not constitute an impairment

Sounds like a fantastic system, @MadMonty.

When you enable XMP (after you're sure the CPU is good and stable, of course), it might be worth spending a tiny bit of time seeing whether your DDR5 sticks can be tweaked a little further.  I've just gone from 32gb with really timings to 64gb with very loose timings, and I've gotten nearly all the lost speed back purely with a bump from 3600mhz to 3800.  Memory tuning is hell in my experience when going beyond this, but for a couple of evenings of gameplay and a night of stress testing, I think it was worthwhile.

Congratulations again on your new system!

Just received and installed everything. I kept my old windows 10 and had to reinstall some drivers and Ryzen Master (showed a 6 core cpu before reinstalling).

After all, I am not that impressed in DCS. While having like 30% more performance in Cinebench R23, I hardly notice improvments in DCS with VR(G2).

 So is the 7800x3d just also limited with  current DCS or are there any hints what I could look for…

There is no point for no one to buy this apu at all. Another cheaper cpu with a dirt "cheap" gpu will do a better job. The gpu part of the apu is way faster than other apu's so you can play games at 1080p with low settings on it, but thats it. For pure cpu power buy something else.

Run DCS in full screen at your monitors native resolution. Perhaps also confirm that you're running the multithreaded exe. It should be the default behavior if you're on the latest version and launch from the updater shortcut, but its possible that you may have an old shortcut directly the ST game exe. The 4090 still isn't really all that amazing with a G2 in DCS, but I know the full screen thing can cause some obvious stutters, and the performance would be noticeably worse in ST. I experienced the former building a squad mates 7950x3D and 4090 system. I have the same with a 7900XTX, and happy with the performance at over half the cost. Also using openxr toolkit might offer better results in general.
