Both are from 2015:

That Broadwell-cpu is an exception. It is the only series for the desktop where Intel produced capable integrated graphics. Btw, it is also a very strong processor.

But it was released immediately before the next cpu generation was released. It got no real marketing, and support for it was abysmal – some to many games just produced a black screen with it. Based on its performance and pricing I'd have liked to recommend it, but given its socket and its support issues that was almost never a good idea.

Normally you'd compare the A10-7870K to the integrated HD graphics of a Skylake or Kaby Lake cpu, it beats those easily.

The R7 GPU architecture is not from 2015. R7 came from 2013 with the 200-series of AMD GPUs, and was the second generation of GCN.

Not to mention the few available Intel parts with those GPUs cost an arm and a leg.
