Upping the clocks and doubling the GPU compute units would make a significant impact. It would be the equivalent of going from a 6600xt to a 6800xt. That's also assuming no performance improvements to AMDs RT implementation.
Doubling the GPU compute units is a change in architecture. They did NOT do that last gen at all. They didn't touch the board design GPU.
Also dedicated AI ML is not needed for RT, unless you are referring to upscaling technology in which case RDNA 2 already suffices as it has DP4a support (XeSS) or can just rely on FSR 2.0 or TSR, which is like 80% of the way there already.
Are you trying to go on record like most of the console warriors here implying that there is no more requirement to advance GPU performance because the games that are out are underutilizing the hardware? Please say you aren't in that camp. I have yet to see any game on the console running at
native 4k/60FPS with any sort of
heavy duty RT - which would be a sound argument if there is proof of such a game. How much GPU design you think would be needed to make the Matrix demo run from 1080p/30FPS to native 4k/60FPS? Certainly not a PS5 Pro.
The above arguments could have been made against the PS4 Pro as well, and yet it happened.
Previous generations aren't a guarantee of future requirements. Have you ever heard of this before when buying stocks that are risky? "Past performance is no guarantee of future performance". Why do a lot of you guys think requirements, costs, design, etc.. are completely 100% linear in time? I don't understand this logic.
It seems a lot of the console warriors on these boards shoot for the moon whenever something new hardware-wise comes out in their respective camps. And 100% of the time, it's shooting way too far. I don't know if you guys actually believe you'll one day get a supercomputer at the price of $500 or if you are just creating an illusion of getting such luck. The PS4 Pro, despite being 2.3X the performance of the PS4, was not a brand new architecture that advanced gaming for the last part of the generation. It's results spoke for itself - just some added pixels and options for performance/quality for the most part without anything else special. It was afterall only a $100 more.
