PlayStation 5 architect Mark Cerny claimed in August that Sony’s next-gen console would have hardware-based ray tracing (“There is ray-tracing acceleration in the GPU hardware”) , but the reality may be a little different.
Hardware leakers have discovered new information pertaining to “Oberon” and “Ariel,” which are believed to be APU variants for the PS5. There is no indication of ray tracing (RT) or variable rate shading (VRS) in either.

1: Navi 10, means no RT, VRS etc
the one said VRS/RT is the one said L1 per CU = navi=Klee, or Tommy not AMD
2: (ARDEN) showed RT
if there is RT, it will showed up as HW feat
because XSX is RDNA2 pic.twitter.com/8hdoorFyJK
This is not the case for the Xbox Series X’s “Sparkman” and “Arden” chips. RT and VRS are mentioned for both, which seems to confirm that Microsoft’s method will be hardware-based.
The findings open up the possibility that the PS5’s RT/VRS implementation will be done via software. It’s pointed out that Ariel is a Navi 10 (non-RDNA2) part, which lends credence to the lack of hardware-based RT/VRS for Sony’s console.
Both the PlayStation 5 and Xbox Series X have yet to be revealed in full, but it is being rumored that they are very close in power. In a recent report, it’s revealed that Sony’s next-gen console is ahead in terms of performance, but the gap is expected to be closed before release.
