I never said it was a good idea, or would result in a good product (consoles are budget systems).
The Dell laptop can be configured down to a 1300 USD price-point, retaining two GPUs (one with ~2.5TFLOPs), and a high speed Intel CPU.

You would probably only need a GPU of around 800-1000Gflop to match the Playstation 4.
Provided it has sufficient texture mapping, geometry and render output pipes.

AMD's Ryzen APU's with a 12-25w TDP would fit the bill, the caveat then becomes bandwidth, which the APU's obviously lack.
GDDR5 tends to be fairly power demanding.

Yeah, my solution is stupidly overpowered for what would be demanded from it.
GDDR6 and HBM 2 offer more bandwidth per watt, compared to GDDR5: they will be nice to have in laptops and similar devices.
I doubt Sony would want to include expensive tech like HBM in a portable console, assuming they have a desire to target the masses like Nintendo.

Finding a way to store PS4 games on a portable device will probably be the most challenging problem to overcome.
SSDs are obviously pretty expensive for the capacity they offer, and who would want a hand-held device with a HDD in it.
Then again who would want a portable console with:

• Active cooling, that requires the device to have an air vent.
• Roughly three hours battery life (running AAA games).
• An SoC that launched in 2015.
