While the smaller cards may look like better price/performance at first, there tends to be some non-linearity to it as well as some extra consideration. For a single rig of just 2 GPUs, it's quite possible that the lower end GPUs do continue to make sense. For rigs with more GPUs, you need to consider the price per "density" as well. If you go with more of the lower end cards, you run into a limit on how many can be put into 1 system effectively and end up having to build additional systems, which means additional cost to continue scaling.
This is the speed I'm getting on a 4070Ti Super AI TOPS right now:
-----------------------
* Hash-Mode 1000 (NTLM)
-----------------------
Speed.#1.........: 144.2 GH/s (14.89ms) @ Accel:128 Loops:1024 Thr:256 Vec:8
And on the MSI card:
-----------------------
* Hash-Mode 1000 (NTLM)
-----------------------
Speed.#1.........: 143.2 GH/s (15.05ms) @ Accel:1024 Loops:1024 Thr:32 Vec:8
So a bit above the 133GH/s, which may skew the numbers a bit.
If we use your numbers for a second:
620€ for 92GH/s (4070 ASUS Turbo)
vs
830€ for 144GH/s (cheaper 4070Ti Super)
vs
1000€ for 144GH/s (AI TOPS)
This gives us:
6.73€/GH/s for the 4070
5.7€/GH/s for the 4070Ti Super
6.94€/GH/s for the 4070Ti Super AI TOPS
So while the AI TOPS variant is indeed a little worse due to it's price, the cheaper price you have for the 4070Ti Super is actually better than the price you have for the ASUS 4070 Turbo. Still, as mentioned, in this case you're right that the smaller GPUs may end up being more cost effective, especially if you aren't planning on scaling to more GPUs later. If this were a larger rig, however, like 8-10 GPU, the 4070Ti Super AI TOPS or the MSI variant are ideal due to their density, power, form factor, and price. The only major problem now is that their availability is potentially declining as they are phased out for the 50 series cards.
>Ok, so as 3.0 x4 is the same bandwidth as 4.0 x2, all of the mentioned boards would be fine, perfect.
I don't know about this. While the lane configs you mentioned _might_ be ok, I wouldn't count on them being _physically_ possible. Most consumer motherboards these days are not built with multi-GPU as an intended use case.
