This seems like a misnomer. This seems more like rendering API architectures more so than GPU-architecture.
Which is still important: Immediate mode vs Tile-based is a big shift in overall style. And GPU-hardware is designed for particular software architectures (because the CPU will be inevitably invoking calls in a certain pattern).
But it'd probably be more accurate to call this blogpost "Rendering Architecture Types Explained" moreso than "GPU Architecture". A modern GPU running DirectX 9.0 or OpenGL 2.0 would still be immediate mode for example.
