I think this is why you mostly see these cheap articles called out as being ideal for gaming rigs where you're highly likely to be adding a dedicated GPU anyway. Even a low end card like a $120 RX 570 is going to be 600+% faster than the built in Intel GPU:

Even for video editing the math might change a bit since modern video editing apps can leverage GPU for rendering.
That said, I agree with the folks who say that AMD releasing desktop chips built on Zen 2 with built in GPU cannot come fast enough.
