Althought the consoles may have 8c16t, they're also a gen behind (zen 2) with limited clock speeds to keep them under a specific power envelope. From the numbers we've seen the 6c12t 5600x should smash that. I think it just means game devs will start programming for X threads instead of 1, or 4 like we have today. They'll become more scalable. None of that removes the fact that at any resolution 1440p and above the bottle neck is still going to be the GPU even if you've got 2x3090s. For gaming you just need "enough" threads and then the highest IPC and lowest latency you can get which at this moment appears to be anything in the 5000 series lineup.
