>They said there was no benefit and produced no proof of that
Someone else already explained the cross-CCD latency penalty, and some shitty game engines proved it's bad to use both CCDs in latency-sensitive tasks.
A 7950X3D performs worse than a 12600K in Total War: Warhammer III because the engine's trying to use all available CPU threads.
AMD initially thought of releasing a 5950X3D with 2x CCDs with a 3D stacked chiplet; their internal tests showed the variant with 1x CCD was optimal for gaming.

If you're wondering why Warhammer 3: Total War seems to favor Intel CPUs, the game engine's old and janky as fuck.
It doesn't know how to properly utilize AMD's dual CCD CPUs.
If an Intel hybrid CPU has too many ecores (like i9s), the 1%/0.1% lows completely tanks.
Creative Assembly employees have been requesting management to invest the resources to unfuck it.
