Let's see... cards that I've owned which were mentioned in the article are the VGA Wonder, the A8-3500M, the HD 4870 1GB, the HD 7970, the R9 Fury and RX 5700 XT. I've also owned an EGA Wonder and HD 5870 (not in the article).
I don't understand why Sami focuses on the two places where the 1st-Gen APU was least successful, in the low-power (Brazos) and desktop (Llano A8-3850). Brazos was was designed to compete with the Intel Atom in Netbooks which were kinda cute-looking but extremely limited in capability. They were so bad in fact that people stopped buying them and extinction set in. Desktop Llano wasn't really competitive because with an unlimited amount of electricity, the efficiency of Llano was overshadowed by the fact that it couldn't keep up with a lot of high-end discrete cards.
Where AMD Fusion really shined was in the mobile Llano platform because it an incredibly efficient and solid-performing IGP, the Mobility Radeon HD 6620G. The A8-3500M and its rival, the i5-2520M were like two sides of a coin. The Intel APU dominated in CPU-intensive workloads while the AMD APU dominated in GPU-dominated workloads.
They weren't equal sides of the same coin though. The A8 was "heads" and the i5 was "tails" because the A8 was far more balanced and therefore more versatile than the i5. While the A8 was slower in CPU-intensive tasks, it could still perform them to completing, it just took longer. However, in a lot of GPU-intensive tasks, specifically games, the i5's pedestrian HD 3000 IGP was completely useless. Several games that were playable on the A8-3500M were completely unplayable on the i5-2520M, assuming that they would even load.
Back when Tom's Hardware was good, they did an extensive 23-page review of the A8-3500M. They mistakenly called it a desktop-class APU (it's mobile) but it's what convinced me to buy my old Acer A8-3500M craptop. It's still decent for most tasks today, 9½ years later:
