Well big Navi is a vague term for me - will the 58xx XT be the same core as the 59xx XT or will there only be a 58xx? I can see a 60 CU about part being less than 300w but anything higher as in a 72 CU part and up??? Would require HBM2 or 3. Will AMD compete with the Titans? They tried with the FE but I think they failed while it is a powerful card in its time.
As for ray tracing support I am not sure how AMD is going to handle that - chiplets do make a lot of sense in that respects, add in some physics hardware, sound, encoding/decoding and keeping the GPU more CU orientated would be very interesting design change. Yet unless this hardware is available to the lower tiers - it won't push ray tracing into the main stream. As for RTX in comparison I consider it a failure so far but does establish a base to build upon which I am sure Ampere will turn up the performance and hopefully make it a very desirable usable feature which right now it is not. So if AMD has a Ray Tracing, physics maybe, encoding/decoding chiplet that is used from top to mid and even lower cards that does ray tracing right - main stream will probably happen. I just don't see that this year.
For this year big Navi may just be a 60CU 384bit memory bus part, no ray tracing - I see that as most likely. Next year AMD I see will have fully functional ray tracing that actually would be worth while, if anemic as RTX I would just pass on it.
In the mean time the 5700 XT Lisa Sue is kicking ASS!
