High end all in one emulation

I came across this video about a high end all in one emulation hamdheld. It claim to emulate PS2/PS3/SWITCH/3DS/GAMECUBE/WII/XBOX games. It seem to good to be true to me. I wonder if this is legit
and better than downloading emulators and play from our computer ? Kindly share your point of view.

The emulators won't come with the device, I presume you will have to download them yourself
The specs are certainly not bad, 4 P-cores and 8 E-cores at those clocks could certainly run most of those emulators just fine
I worry that it only uses integrated graphics, but there is a Thunderbolt 4 port that you could connect an eGPU to so I'd say the device is legit, at least on paper
