I am not a pro in the subject, but does it mean the data still needs to reach the bridge on cpu first? What I am thinking of now is that with DX12 there's already a direct access to SSD's for fastes data copy to NVRAM, why then couldn't this benefit of losing some hops whenever reaching for data that is already onboard?

PCIe latency is a few orders of magnitude lower than NAND flash read latency, so the extra round trip to the CPU's PCIe root complex doesn't matter.

Not latency, but bandwidth to the GPU, matters for asset loading. Can the GPU load assets directly from its own SSD, as the PS5 does, or is this just an SSD the processor can use as a "disk"?

surely that data copy would not be on the fly, it would be preloaded, SSD's ~8GB/s could not keep up with GPU's ~350GB/s

Yes, it does, although DMA means the CPU will not need to process it. It's like any other M2 drive in your PC.

nVidia generally disables/does not use ReBAR as it either shows no improvement or degrades performance. AMD may be a different story, but that isn't what this card is.

That’s very incorrect. Nvidia requires that every piece of firmware along the way be updated to support it, and won’t enable it unless they are. However if they are, depending on the game there’s definitely uplift.
