How long until a ps4 level $400 hybrid is possible?

I'm pretty sure this will be possible using Tegra Xavier, scheduled for Q1 2018, so in few months (probably). With 512 cuda cores we're talking min GTX 750 performance, so very close to the base PS4, but without clocks, bandwidths etc it's hard to say.  I'm not sure about the cost though.

Xavier's TDP is in the 20-30W range, way too high for a hybrid console, which can stomach only up to 5W (give or take) without getting too hot or draining power too fast. Also, most of it's power comes from the Tensor cores, but Videogames don't make use of them (hence why Volta is a pure HPC card with no consumer models).

With some custom design, you can however probably reach about XBO power right now with a 14-10nm chip without consuming too much. But since such one would need to get designed first, it would still take about 2-3 years until it's release.

In 7nm, a PS4-level APU with about 5W TDP is possibly feasible if one looks what Raven Ridge can pull at 15W TDP, but I wouldn't bet on any earlier than this for a technological feasibility of a PS4 hybrid for less then 500$
