Is upgrading from a Ryzen 9 7900X to a 9900X3D worthwhile with an RTX 5070 Ti?

I built an AM5 system with a Ryzen 9 7900X as a temporary processor and am considering replacing it with a Ryzen 9 9900X3D. The system also has an RTX 5070 Ti and 6400 MHz memory. Given the rest of the hardware, would the extra 3D V-Cache provide a noticeable gaming improvement, or would the upgrade be difficult to justify?
Answers
The 9900X3D would improve performance in some games, but the difference probably won’t be noticeable across the board with a 5070 Ti. The biggest gains tend to appear in CPU-limited games that benefit strongly from extra V-Cache, while GPU-limited games may perform almost identically. It may be better to keep the 7900X until you can identify a specific game or workload where the upgrade makes a meaningful difference.

QuietMarble18: Games such as Cities: Skylines 2 can be heavily CPU-limited, so extra cache might help in certain situations, but the benefit depends on the workload and settings. For Tempest Rising, there isn’t enough general evidence to assume a major V-Cache advantage.
