AMD has higher IPC (instructions per clock) than Intel generally, so clock speed number does not compare exactly.
Brand new Ryzen 5000 beats Intel single core performance even below 5ghz, finally after so many years being behind, Ryzen 3000 is generally 10% slower single core performance to Intel but better value for core count. Threadripper 3000 (TRX 40 sTRX4) is same single core performance to Ryzen 3000 but scaled up to get get 24 - 64 core cpus amazing for productivity if you need it for work. But for simracing complete and utter overkill. Maybe if you do video editing its worth getting, but even then a 16 core 3950x is far more sensible choice for that.
Why are you thinking of going for TRX40, sTRX4 though? That is Threadripper not Ryzen, and as above is only really worth getting for productivity. There is no news on Threadripper 5000 coming out, maybe sometime next year, I mean its currently dominating its market segment over x299 so no real need to.
I think you may mean Ryzen AM4, a B550 or X570 motherboard with a 5000 series CPU (5600x 5800x and 5900x all being released on the 5th of nov) will be the fastest CPU on the market for gaming until Intel Releases Rocket Lake next year and there is doubt it will be as good as they are going to use the 14nm process but on a new architecture.
