I'm very suspicious of questions posted about brand-new products. I admit yours is one of the better-written ones I've seen, but Super User gets a host of awful questions about whatever new technology was just announced, even if it won't be released for months. Super User is not a product review site, or a discussion board, and most of these new-product questions are more appropriate for one of those.
Your question's title asks if the new product "performs better" than the older tech, and the question body goes on to ask why the older tech wouldn't perform as well. It has that subjective smell to me. In particular, you state the new tech seems "at a glance" to do what the old tech does, which sounds to me like marketing fluff.
So that's my take on the overall class of questions, and why in particular I think it applies to your question. Thanks for asking this question, though. If the community or the other Super User moderators reopen it, I'll take this into account when reviewing questions in the future. I'm happy to get the community's feedback on it.
