QuotePark explained that Samsung successfully shrunk down the RDNA architecture in the first-gen product as the company was "focused heavily on minimizing heat, because mobile devices do not have fans like gaming consoles."

Smartphones can have fans. But if that is a non-starter for mainstream Galaxy phones, I bet they could find some way to upgrade the passive cooling for more $$$.

Qualcomm: No AV1 until 2023, needed to buy Nuvia to have a chance of competing with Apple.
Samsung: Impressive chaos in the Exynos division, won't even commit to using its own SoCs in flagship phones.

Hopefully the AMD collaboration bears some fruit. Try putting it into a laptop or mini-PC.

QuoteFor instance, in our tests of the Xclipse 920, we found that Samsung's offering was up to 30% slower in 3D Mark Sling Shot Extreme with Unlimited graphics than the Adreno 730.

Pretty cherry picked example because you also found that the Xclipse 920 performs 30% better in GFXBench Manhatten.
But yeah on average across 16 benchmarks it performed 9% worse than the Adreno 730 GPU according to your own comparison charts. This would be a much more valuable and balanced statement in the article.
