I hope there will be a followup publication about that version.

There's been a fair amount of R&D around assisted encoding, using HW encoders for coarse motion estimation, frame type decisions, that sort of thing. MCW saw about a 20-25% speedup in x265 using that, which wasn't really worth it in the end. If the Gen2 processor is better suited to that, perhaps they can combine some higher level algorithmic tuning to get a bigger share of the potential efficiency of codecs.

However, the way they've leaned into optimization for memory bandwidth would preclude much low-level tweaking. But maybe a faster hybrid mode as mentioned above? Maybe try encoding each frame different ways on different processors and then synthesize the data for a final pass?
