Maybe, but regardless of what bench you use to measure singlethreaded performance. Cinebench, CPU-Z, web browsing, superpi etc. The results are consistent.
A large cache is helpful because it can be used preferentially over RAM, which in Zen's case, is a higher latency transaction than it is on Intel. As is the core to IO latency, or core to core, for the multi CCD chips, whether this platform generation, or previous ones. Gaming, and other real time tasks, like low latency, and they like high ST performance. Whether that low latency is achieved through faster frequencies, or by fitting things in cache rather than RAM, doesn't really matter. Except you can't fit everything in a ~100 MB cache. Hence why I have to correct people who say RAM speed doesn't really matter on X3D, because it does. I've tested it.
Good luck getting below 60 ns latency in AIDA on Zen though, I've got 57 ns but that took lots of effort.
The point is, ST is always relevant, a large cache is sometimes relevant. Like running out of RAM capacity, it makes no difference whether you have 32 GB or 64 GB of identically clocked RAM for performance, if you're only using ~20 GB of it.
In my experience, online games scale better with frequency, not cache size. Might be something to do with their unpredictability compared to singleplayer games.
A funny thing is the non X3D chips actually have better AIDA RAM latency than the X3D ones, because they clock higher.
I got 55 ns on my 5950X and 58 ns on 5800 X3D.
Raptor Lake with a good memory controller you can go lower than ~45 ns.
