There is probably no good answer to your question. These benchmarks are also fairly old and primitive by modern standards. Frankly, I don't think that much can be learned by looking at them. These ridiculously high frame rates mean that the GPU is doing very little work per frame, so the performance-limiting factors could be things like synchronisation or frame scheduling, which will show themselves very differently in a real-world game or app.
For general gaming benchmarking, right now there is only 3D Mark Wild Life Extreme, plus a handful of games (BG3, Metro, Resident Evil). To get a better picture one would ned to look at that.
If you work with scenes that need this much RAM, sure. But what game would that be?
