Another thing to consider is what YOU want out of the card. If the only thing you consider is performance, then the above post from BMD is fairly accurate, probably. 4 SM is not that big of a deal, but the OG 4070 Ti is afforded a higher PL and that probably will translate to 10-ish% differential with the 4070S. However, I personally prefer cards that are not oversized behemoths and, seeing how it was the case for the 4070 Ti, I would think that the 4070 TiS will feature only massive triple fan, triple to quad slot solutions. The only way to get something reasonable would be the FE in this case, and that isn't available everywhere. That annoys me, I would like something more compact, install and forget, so I am looking at the 4070S in this regard, seemingly plenty of choice for compact-ish cards. And the 220 watt TDP is fairly easy to cool.
This is all a long way to say that I am too lazy to install the support bracket that came with my Torrent.
