Flawed logic as usual, RDNA 1 dosen't have built in RT cores, AMD doesn't want to go the exact same route as Nvidia, which included dedicated ray tracing cores and would rather use a mix of dedicated and non-dedicated hardware to give devs more flexibility.
next gen console wont have RDNA+, logically next gen leads to RDNA 1 - GCN for an easier Backward comp
not going to answer that r600 and EUV, all i'm saying is consoles cost around 400 -500$ and due 2020 don't expect too much.
Pure conjecture on your part. Deal with the evidence for once.
Xbox and PS5 both have hardware raytracing, which isn't just shaders as RDNA 1.
No one said anything about AMD hardware being equal to nVidia's RT cores, I'm sure there are many ways to skin the preverbial Raytracing cat.
Also backward compatibility with GCN means didlly squat for the xbox as long as MS stick with direct x, I'm also sure a few Sony patents mean they don't particulally care either.
Literally all MS and Sony have to do is pay for these chips to be made now, design is all done or being finalised now. All in all, based on 100 million in sales your unrealisitic, for a console, $600~700 PC 8 core CPU and Navi GPU combo, cost $100 at most, per chip.
I am not saying Xbox and PS5 will be tflop monsters, they probably won't be clocked high enough for that kind of performance, but they will certainly not be RDNA 1 and your reasons for believe it will just don't add up.
To break it down simply:
RDNA1 = No hardware assisted raytracing
RDNA+ = Hardware assisted raytracing
Xbox and PS5 = Hardware assisted raytracing.
Even if it is not RDNA+, it certainly isn't RDNA 1.
It's unlikely AMD designed 3 different hardware assisted raytracing projects, 1 for MS, one for Sony and one for themselves. It's likely that they are IDENTICAL solutions to the same problem.
Surely you can see the point here? or are you that blinkered in your belief that you are right you cannot accept what I am suggesting is probable.
You could well be right, I accept that, I am just pointing out to you evidence and more dot connecting that is more compeling than your arguments, that indicate you are in fact barking up the wrong tree.
You say don't expect much, but I'm affraid I do, AMD has form for giving console makers first dibs on technology, so expect something that is likely to be released in the summer next year in the PC space to be the minimum tech level in the consoles.
