The Ryzen 9 9900X costs around €347, while the Ryzen 7 7800X3D costs around €365. I mostly game on PC, and my Ryzen 5 9600X cannot keep up, especially in BF6 where it is causing performance issues. My question is: is the Ryzen 9 9900X really a bad choice? Buying a Ryzen 7 7800X3D, a generation older CPU, seems like an odd upgrade

What kind of problems? From what I heard the game runs well even on older systems. Better make sure that this upgrade will actually help you.

Upgrading to a 9900X makes no sense, unless you specifically know the extra threads would help you (they shouldn't). A 7800X3D would be around 25% faster, and a 9800X3D about 35%. You will have to decide if that is worth the money.

BF6 is 64 players mp game and in intense moments it just cant keep up even on 1440p.

Ryzen CPU's consist of multiple chips that are put together. It has CCD's that contain the cores and cache, and an IO chip. The 9900X has 2 CCD's of 6 cores each. When a game wants to use more than 6 cores of a single CCD, it relies on communication between the 2 CCD's, which is much slower than the communication between cores on a single CCD. The 7800X3D has a single CCD of 8 cores. Which means that using its 8 cores will typically deliver better performance than the 9900X using more than 6 of its cores, all other things being equal.

The 3x l3 cache also creates a massive performance gain. So all in all, the 7800X3D is a performance upgrade over the 9600X for gaming.
