MS Executive says Devs will need to learn how to work around Slower SSD on XSX

Not sure if its that simple Don.. From what I am hearing, the RT Tech in the XSX might make a bigger splash than the one in the PS5, and considering the XSX offers more powerful hardware across the board it might be more than just pixels and framerates, but maybe better lighting, shading and higher textures etc. The PS5 will offer quicker load times and faster draw distances however I am still in the "Wait and see" approach with the PS5's super hyped up SSD because from what we saw at the PS5 reveal, nothing looked like the XSX couldn't render better. But will "wait and see"

Im hearing the contrary then. People are saying that they dont know if the RT cores in the RDNA2 are tied to the compute unit or are separate. If they are tied to the CU then the XsX could see big improvements as it will have core RT cores and more CU's, but if its not the RT cores will be a fixed number that both consoles will have and clocked faster on the ps5 and will better performance. The XsX could use the extra compute power  for ray tracing but it wont outperform the dedicated RT cores. 

This. We don't know which way the RT cores will go in Big Navi. We need to wait on more detailing.

Sure thing, RT could be proportional to the CU count, exactly the same for both consoles or PS could have more for all we know. That is something that will need more deep dives to be sure.

But if anyone have any source for the RT count on both consoles that would be great.

Anyway the UE5 demo didn't even use these cores on PS5 even though Epic said it was tailor made and optimized for PS5 for 6 months.

Could go in any direction.

AMD could make the RT cores a function of the amount of CU's. I.E. Like with the TMU's where you have 16 TMU's per CU.

Or AMD could just arbitrarily throw a huge number of them onto the silicon like 1024.

Or AMD could simply build out it's CU counts and add additional hardware to accelerate RT tasks on the current shader pipelines.

Although it's been stated "cores" implicitly prior, so it's likely one of the top two scenarios.

As for Epic. They were never going to 100% optimize their engine for a technology demonstration on an engine that is unreleased and unfinished for a console that is unreleased and unfinished.
There is still performance and optimization left on the table.

I would have liked Epic to have leveraged the RT cores to bolster the global illumination in the demo for a real generational step forwards in lighting.
