AMD Rushing in Ryzen 7 9800X3D, Expect Product Launch Late-October
Facing poor sales of its Ryzen 9000 "Granite Ridge" desktop processors, and with the spectre of Intel's Core Ultra "Arrow Lake-S" looming, AMD is rumored to have given its desktop processor roadmap a shakedown. The company is working to rush in at least one of the three upcoming Ryzen 9000X3D series processor SKUs. The Ryzen 7 9800X3D is a successor to the popular Ryzen 7 7800X3D. It pairs the new "Zen 5" microarchitecture with 3D V-cache technology to boost gaming performance. AMD is allegedly rushing the 9800X3D for a late-October launch. If this chip meets its performance targets (of around 15-20% over the 9700X), then AMD hopes it could take the edge off Intel's Core Ultra 200-series.
Launch of a Ryzen 9000X3D series product-stack became inevitable when AMD confirmed that the "Zen 5" CCD has silicon-level preparation for 3D V-cache (such as TSVs over the region with the on-die L3 cache that interface with the stacked L3D silicon), however, it was expected that the non-X3D Ryzen 9000 series, such as the 9700X, would perform close to the 7800X3D in games, giving AMD room to launch the 9800X3D in Q1-2025. Prior to the 7800X3D and Intel's 13th Gen Core "Raptor Lake," the Ryzen 7 7700X nearly matched the gaming performance of the Ryzen 7 5800X3D, and so something similar was expected of the 9700X. Of course things didn't go to plan, the 9700X fell significantly short of the 7800X3D in gaming, resulting in mixed reviews and low sales.
The 9800X3D won't be the only chip from the 9000X3D series, there are also the Ryzen 9 9900X3D and new flagship 9950X3D planned, however, zhangzhonghao, the user behind this leak, says that the dual-CCD processors will do something different to the 7900X3D and 7950X3D to attract the class of buyers that wants both flagship gaming performance and productivity performance competitive to the Core Ultra 9 285K. The user did not elaborate on what these "new features" are, but if we were to guess, it's likely that both CCDs on the processor get 3D V-cache. The 9900X3D and 9950X3D are on-track for a Q1-2025 release.

There’s two.
AMD never said 9000 CPUs were for Gaming as a first reason to buy one. There are clear architectural differences between X3D, G and X/Non X CPUs.
In theory 7900X3D is great, the problem is the tread scheduler which runs it as a simple 6 core in many games making it perform like a regular 6 core with 3D cache making it inferior to 7800X3D. Look at BG3, Cyberpunk, plague tale, Mirage, watch dogs, HM3. In some games it performs great when scheduler works great and slightly above 7800X3D, but they are the minority it seems.
It is good that we are both satisfied. And if you do productivity, 7900X3D will be a better choice.
The only saving grace I can see for the 9900X3D is if they add 3D cache on both ccds and mske them run at same speed so you can ditch the tread scheduler. In that case it will probably outperform 9800X3D in many cases except when cross ccd latency gets to high. This option however will raise it's price quite a bit :/
Hopefully, the architectural issues (like inter-CCD latency) don't bleed over into the 9800X3D, but I and many others aren't holding our breaths at this point.
The inter-CCD latency has vastly improved with AGESA v1202 (180 >> 70-80) for 9000 but yes there is a latency inherently and by design when you have multiple core dies on same package
2nd
A single CCD CPU, like the 9800X3D will be, won’t suffer from that latency
