I am considering buying a prebuilt  PC coupling a Ryzen 5900 series with NVIDIA 3090 graphics card. I do not think I need the 5950X. Two options then are the 5900 and 5900X. According to an article I read I quote:

"Ryzen 9 5900 is essentially the power-optimized version of the Ryzen 9 5900X. The Ryzen 9 5900 retains the same 12-core, 24-thread design with 64MB of L3 cache as its counterpart. Unlike the Ryzen 9 5900X's 105W TDP, the non-X model is restricted to 65W.

With a stricter power limit, the Ryzen 9 5900 obviously arrives with lower operating clock speeds. The processor has a 3 GHz base clock, which is 700 MHz lower than the Ryzen 9 5900X. The boost clock, on the other hand, didn't suffer a huge reduction. The Ryzen 9 5900 easily boosts to 4.7 GHz, only 100 MHz lower than the Ryzen 9 5900X."

The 5900X costs $300 more than the 5900, which is substantial.

Does anyone have any advice on a compelling reason to go with the more expensive 5900X for flight simming (P3D and eventually MS2020)?

 

Thanks,

In my opinion, that's like buying an expensive Ferrari (RTX 3090) and saving money by using lower rated tyres. Besides that, MSFS/P3D/DCS/X-plane might use more cores in the future, then higher all-core clocks/TDP capable CPU will be needed.

Thanks, I like that analogy. It’s only $300 more, and over years of use, the cost differential is minimal for increased flexibility for the future.
