We don't have to speculate. If you look at the actual tweet from Firaxis, they are recommending a Ryzen 9 5950X which is a 16 core/32 thread CPU or a i7-14700f which is a 20 core CPU (8 p-cores and 12 e-cores). So they are recommending more than an 8 physical core CPU for 4K/60 High (the specs for lower resolutions/framerates are a lot lower) Maybe a newer (AM5) 8 core/16 thread CPU will be equivalent. Like the 7700X is 8 core/16 thread but has better single core performance than the 5950X. Just depends on how well the game utilizes the extra threads.
