On RTX cards, the bulk of DLSS software runs on Tensor co-processors.Ray Tracing will be the consoles' Achiles heel this generation. Spiderman at 4K30, with non reflective Ray Tracing, is an early sign the PS5 will struggle with Ray Tracing, especially in open world games.
The consoles lack a hardware based DLSS solution, like the RTX 30 series, so ironically it's the consoles which are "brute forcing" 4K, while the 30 series on PC can fall back on DLSS and AI upscale to 4K, while doing full Ray Tracing and post effects.
XSX and BiG NAVI can run tensor math via ML dot math feature within CU's stream processors. ML dot math feature's resulting datatype is different from RPM feature.
Tensor math requires mixed-precision
PS5 has hardware checkerboard support.
