AMD Ryzen 9 7950X3D or Intel i9 14900KF

And despite the 7800X3D only going to 5 Ghz, it tends to beat the 14900K at up to 6 Ghz, in benchmarks.

I see it score way lower in these. Not sure which test is the most relevant to DCS though.

Despite its troubles the 14900 still seems to be the king here. I also see these performance bug reports where the 7800X3D is getting 25FPS vs 120+ for the Intel  something is certainly wrong there I’m sure.

Cinebench is a synthetic benchmark that focuses a lot on parallelisation. It basically scales 1to1 with the number of cores. Completely unrelated to gaming performance. The other one I don’t know.

For a good representation of DCS performance you should use Heaven Benchmark, which also happens to be DX11.

Yeah, the 7800X3D is a poor CPU if you run important software that does a lot of work in 1 big batch. But as I've explained above, games are almost never like this, because they have a very limited time to draw a frame, and then start over doing the calculations for the next frame. So it's a lot of short jobs. The X3D-CPUs work very well for those.

If you don't game, and run the big batch (often called 'productivity' software), then the 7950X and 14900 are indeed the fastest.

And if you do both, then the 7950X3D is a very good compromise, that sacrifices a little in both, but is still very good at both. And the 14900 also works fairly well for those use cases, if we ignore the degradation and the power usage.

There are people on this thread with Intel too but the OP is using the 7800X3D  FWIW I get 120 FPS on that test miz and that’s GPU limited, didn’t test what I’d get if I removed that

Yeah, pretty sure I had looked over that last time you mentioned it.  Admittedly didn't read the whole thing, but IIRC it wasn't just AM5 CPUs, there were Intel CPUs too.

So it's not an exclusively mysterious issue with AMD CPUs; the 7800X3D is still currently the best CPU for gaming, and the Intel 13th/14th gen CPUs are still prone to destroying themselves

Yeah that’s why the report is so puzzling

It's really not that puzzling (unless you're a 14th gen Intel CPU owner who insists on looking at it as some sort of proof the 7800X3D has issues running DCS lol).  Probably worth considering there are lots of people running DCS on a 7800X3D without issue.

The thread also mentions other CPUs, including at least some Intel models if I'm not mistaken.  So it's misleading to suggest this mysteriously indicates much of anything about the 7800X3D alone.

Great thread!!

I'm bottlenecking on my current setup, details below!

Just been quoted this as the best update for DCS.

ASUS PRIME X870-P WiFi - PCIe 5.0, 4x M.2, 2.5G/WiFi7, 8x USB-A, 2x USB-C         £249.98

AMD Ryzen 7 9800X3D, Zen 5, 8 Core, 16 Thread, 4.7GHz, 5.2GHz Turbo, 120W     £479.99

64GB (2x32GB) Corsair Vengeance 6000MHz [Black]   £194.48

Corsair iCUE LINK H100i RGB - 240mm Liquid Cooler   £99.98

Total £1096.43

I would appreciate any good advice based on the above before I pull the plug on it.

Regards

Personally I would go with a 320mm AIO if you have room, which is what I did, I also ditched Asus for MSI but I am running a 7800X3D for a year now so your 9800, which is the obvious choice along with the 64GB Corsair RAM which I am also using, may need a different board for poss overclock, I haven't researched it.  If you are buying from Scan they are pretty trustworthy, been using them for many years. Dropping to a B650 could save a hundred quid, but I haven't done that research like I said, just fed up with being ripped off for features I don't need.

Thankyou...which MSI board please?

Yes I do trust scan very impartial advice, rare these days.

MSI AMD B650 TOMAHAWK WIFI AM5 DDR5 ATX Motherboard LN129282 - MAG B650 TOMAHAWK WIFI | SCAN UK

Is the one I bought, but that was a year ago so may be there is a better alternative, I have used Asus for quite a few years but that was for overclocking Intel chips, I didn't need all that control so tried a change. It does boot slow as it checks the RAM each time but you can switch that off. It works for me with my 7800X3D.

 Thanks all ordered, Went for the 360 AIO.  build in progress.

Motherboard installed all set up and starts OK.

The computer was originally a UKGC build and came to me ready to run, following the move onto the new Motherboard ,Window (10pro) wont allow loadup with my original Profile.

Any ideas where I can go from here anyone......there are options but Im not savvy enough to understand them

Regards

OK Sorted the boot Drive was not the primary drive in the Bios!!!
