Question AMD Ryzen 7 5700X3D or Ryzen 9 5900X?

[_D3vThoR]

I have found those CPU pretty much at the same price, the Ryzen 7 at 242 euros and the Ryzen 9 at 250 euros. I was checking on the main differences between those two CPUs and one of the main choices to go with the Ryzen 7 is because it has a bigger L3 cache (96MB vs 64MB). It also has 6.67 MB/core more L3 cache per core and offers a supports for ECC memory. On the other side, the Ryzen 9 is more powerful and has more threads/core.

Considering as per above, and adding that I am using my PC for gaming and productivity and soon I am going to switch from 1080p to 1440p (wide screen), what are your thoughts? Which CPU should I pick since both have the same price? I am definitely more keen for the Ryzen 9, but never say never as there might be something missing and I want to be sure I am going to make the right decision.

PS: my MoBo has a B450 chipset and AM4 slot, so the ultimate upgrade I can make it is a Ryzen 5000 family as the 7000 family is not compatible. Thanks!

Gaming or “working”… non gaming uses.

For gaming the 5700x3d
For primarily other uses plus a little gaming.. the 5900x

Check to see what the 5900XT is going for, if available. In spite of its nomenclature, it is a 16C/32T CPU and is only ~3% slower than the 5950X.

The X3D is more productive in game loads. Keep in mind that moving up in res transfers more load to the graphics solution so you may be able to tell little difference on CPU side outside of your productivity tasks. I would like the final say on that to folks who have tested them.

Thanks both for your answer. Just to provide more information about what "productivity" I was referring to, I am using my PC for gaming but also for video editing and 3D rendering, that's what I was referring as productivity.

I am aware that going up in resolution will be more a GPU business, but I was also curious to know if on the CPU side this increase will take any effect or not.

Anyway on the paper I can clearly see that the 5900X is more powerful, but what I want to know is how a L3 cache and 8 cores is better than having 12 cores and less L3 cache for gaming Vs any other situation

You need to keep in mind that the 5700X3D is really a gaming CPU. Unlike the new 9000X3D models, the 5000X3D and 7000X3D chips had the extra-cache die on the top of the CPU die, so AMD had to decrease their max boost frequency to prevent overheating (the new 9000X3D processors have the cache die at the bottom so they don't have this issue). That means that the 5700X3D is really not good for productivity. I mean, the 5700X is already not a productivity chip, and it's X3D counterpart is even worse.

And if you expect to play at 1440p you won't probably see much difference in games anyway, but you will definitely get a huge boost in productivity tasks with the 5900X (it's still quite a powerful chip).

Thank you @JayGau for your detailed answer. I'll go with the 5900 at this point, even because, I mean, how much of negative difference I can feel in videogames compared to the 5700X3D? I am currently playing with a Ryzen 7 2700 without any issues, so at this point I guess it all depends on the type of videogames.

Jumping from the 2700 you will feel a big difference. Unless you use a 5700x3d you won’t have a point of reference to feel any deficit.

The 5000 chips are a huge improvement on the 2000 series chips.

I think it's a no-brainer. Whichever you choose between the two, you gonna get a massive improvement in both games and productivity as compared to your 2700, but the difference in games between the the 5700X3D and the 5900X at 1440p will be marginal, while the 5900X is far superior for productivity.
