Also if Sony and MS can redesign a far worse Jaguar APU and produce the result which we have on PS4... u think they cant redesign a far better and more enegy efficient ryzen apu to fit onto a tablet size device?? Bottom line is a system designed around close platform and ability to code directly to hardware will always be better than general purpose device based on the same hardware.

 

No one codes directly to the hardware anymore, no one writes in Assembly/Machine in 2017, there is no need for it.
But the good thing about that is... It's far easier to retain backwards compatibility and develop software and games.

With that... A Pascal based Tegra can provide 50% more performance for the same power over the Maxwell Tegra (Aka. The chip in the Switch).
And provide 128% more bandwidth. (The biggest game changer for performance at 1080P verses the Switch.)

A Volta based Tegra has already been demonstrated for a few markets like cars... And is set to double the Pascal based Tegra again and is using 16nm at TSMC.
There would be power/performance gains if nVidia shifted Volta Tegra to "12nm" as well of a around 10%...

In short, I doubt we will get a chip that is a Playstation 4 in identical capabilities for many years yet, but we can get "close enough" with hardware available today/soon.

"No body codes to metal anymore" maybe in games by third party development scene, and consoles hardware being off the shelf PC, but even the regular ps4 API has some amount of customization, and many third party games are still utilizing Low level API offered by PS. I'll be surprised if sony first party developers are not using low level API to write directly to the hardware.

regarding the hardware comments I m just pointing out the options of hardware available for a custom design, and sony being a hardware company have shown that they can make a potent chip for a handheld and console, and with a help of a custom API it is possible to achieve graphic fidelity on the levels of PS4 on a handheld, again case in point is PSVita that device was punching above its weight with its custom design SoC with off the shelf hardware compared to similar hardware in other devices such ipad and iphone 5 compared to cellphones now ps vita Still has some of the best looking games.

Look at doom on a two year old chip running on switch, I think Sony can better that
