RX 6400 was also close to the best case performance. Previous tests showed it being frequently outperformed by a GT 1030, while using over 200 watts of power.
Considering this card was very much a novelty with no selling points at all, it would surprise me to find out that it was actually produced in bulk. IIRC it was also priced at something like $260 until recently.
I have to wonder if these cards just didn’t sell at all, and they’re dumping what stock remains? The whole product release seemed more like an attempt to establish their name (show that they actually have hardware, and are putting work into developing it), rather than release a viable product.
I’m pretty sure the intention of that quote is, “I will not be satisfied by merely succeededing, I must see others fail as well.”
