5800x3D vs 5900x
5800x3D vs 5900x
Low quality settings are the best way to evaluate CPUs, as higher resolutions push them to GPU limits and don't truly reveal CPU boundaries. These tests often forecast future performance with stronger graphics cards even at higher resolutions. A 3800x might match a 5900x with a 3070 at 1440p, but a 3090ti will show the gap. Likewise, the 5800X3D is likely to beat the 5900X in most cases. I mean most, since some games depend more on frequency and others on cache. If you're happy with your 3800x results, it doesn't make sense to upgrade now—your current chip will soon be outdated. If you're fine with your stats, hold off another six months for a 13th-gen Intel/Zen4 and revisit then.
You'll likely see some improvements, particularly in the lower frames. The extent of the benefit varies based on the game and your preferences. And determining how valuable that change is depends on your own expectations. If you're already consistently achieving over 100 frames per second, can you tell if the jump to 120 or 130 is significant for you?
I'm searching for the future. My plan was to purchase the best CPU for AM4, and I'll likely keep it for a few years since upgrading to the next generation isn't feasible. Unless it boosts performance by about 10-20 frames per second, it won't be worth it. Edited May 2, 2022 by William2345
If you can improve and sell the 3900x to cover the expense of the new CPU, then it makes sense.
The project is at 3800x, I’m ready to sell but it would cost about $250 extra. Edited May 2, 2022 by William2345
I can't really answer your question. It's up to you. Personally I would just wait to upgrade to the next best thing. I get a feeling the 5800X3D might prove to be a big weird later on. It has a cache advantage over the other chips in the lineup, but it has a frequency disadvantage, and cannot be overclocked. I have a feeling it will play better on some things and worse on others. I think that as the chips age, they'll be about the same with neither one being that advantageous over another. For that reason the 5900X might make more sense since it's just cheaper. But...again I would just wait and get the shiny new when it's available. If you are looking to spend $300 net now, it's possible in a year or two, $300 could buy you mid-range performance that is better than what you could buy today. An example from history: Let's say you had a Ryzen 5 2600 + B450. You could have: A. Bought a 5600X: $300 slot in to an older B450 board. B. Waited a few months and got an i5-12400 for $165, and a $100 B660 motherboard for $265. A would have got you better performance in the here and now, but B would have given you about the same performance for less money, plus you get to keep your older R5 2600+B450 system for another use.
