I can't really judge the accuracy of the rest of the article, but if they can't even get the names of the GPUs they're recommending correct, it's tough to trust the rest of their supposedly thorough analysis. Throughout the whole article, the author refers to the "NVIDIA RTX 40 Ampere series", which is wrong. The RTX 30 series is Ampere [1] and the RTX 40 series is Ada [2].
