All manufacturers have shown their RTX 3070 design, at Palit the same for the GameRock and GamingPro, however another SKU is in the making as they published the news and photos of the new GeForce RTX 3070 JetStream Graphics Card, and it does look nice in all black.
Palit posted this on Twitter it seems, but have a peek. The RTX 3070 JetStream graphics card has a nice dark design with subtle lettering and dual-fan cooling solution. The card is short and thus will have a small PCB. Sitting in the middle of the top side is the dual-8-pin header, and that's why I say that the PCB is small, as the connectors always sit at the end of the PCB.
We already had a chat earlier today with Palit, their product samples are slightly delayed and will ship later this week. We'll try and have this one reviewed by next week then. The announcements for AIB RTX 3070 cards will be Thursday.
