Can AMD Ryzen5 3500u (4 cores, 8 threads) run adobe premiere pro & photoshop properly?

Forget about that APU for Premiere Pro. It scored worse than even a five-year-old dual-core Intel CPU with its integrated Intel HD Graphics 520.

And even for Photoshop, it still scored half as much as even a five-year-old quad-core CPU.

And all this is because Adobe programs do not like low-end Radeons at all even in OpenCL mode, as evidenced by the GPU score and live playback score being so poor.

I think that will depend on what you are editing
