i dont think a 160bit bus would happen but a 10gb card would be possible. although stranger things have happened
what was the last 128bit bus car?

160 bit is awkward precisely because of the memory configuration implications.

They squeezed bus widths on the 40-series cards and the 4070 has a 192 bit bus whilst the 4060 is 128 bit.

Logically you could see them leveraging the faster speeds of GDDR7 to reduce the 5070 to 160 bit but this would then dictate memory configurations of either 10GB or 20GB which are too low and high respectively.

3GB modules would help and permit a 15GB card which would make quite a lot of sense but these won't appear in time for the 50-series.

4060 8GB says nvidia don't care about downgrade :o

I presume you refer to this as a downgrade relative to the 3060 which had 12GB. Funny thing is, the 3060 only had 12GB for the very reasons stated above, namely the 192 bit bus dictated multiples of 6 memory chips so it was either 12GB or 6GB and the latter clearly wasn't enough, even for NVidia. If they'd been able to release a 3060 8GB model then I'm sure they would have.

When I said 10GB was too low, I was talking in the context of a 5070 class card.

Well they also "downgraded" with the 3080 which had 10GB compared to the 11GB of the 2080Ti and 1080Ti before it.

Even still, I'd frankly be amazed if they tried to sell a 5070 10GB in 2024/25 - the press would crucify them.

Yeah. Just can't see it. Bare minimum would be 12GB and even that in 2025 for that class GPU is too little. Needs to be 16GB really.
 
Considering AMD is exiting the high end GPU market at least in the near term, Nvidia has the entire high end market to themselves. They could release a 5080 10GB for a grand and a 12GB one for 1.5 and it would still sell. One thing is for sure, the 5090 pricing is going to make the 4090 look like a budget option now that AMD is not here.

For example the 4070 has 12GB because its 192 bit bus dictates multiples of 6 memory chips, so they use 6 2GB modules. The next step up would be 24GB which would be too much for a xx70 series card.

The success of the A770 suggests otherwise. Of course such a card would eat into sales of their professional cards

It won't be though because the only practical way of doing 16GB is with a 256 bit bus and that's problematic both because they reduced the 4070 bus to 192 bit from the 256 of the 3070 and also because, if they gave the 5070 a 256 bit bus, what do they do with the 5080?

What we'll likely get is the same bus widths and memory sizes for the 5070/80/90 as their 40 series predecessors.

What NVidia should do is:

5090: 24GB on a 384 bit bus
5080: 20GB on a 320 bit bus
5070: 16GB on a 256 bit bus

Agreed, that is what they should do. Let's see what they do do :p

How about let play guess the prices :cry:

5090 = £1799
5080 = £1299
5070 = £799

I did put in higher prices at first , But i then edited it because i noticed Nvidia did drop the 4080 £1199 launch price to £999 for the 4080 super

Maybe they noticed the 4080 didn't sell very well at £1199

They did release an 8GB 3060 later on, with the memory bus slashed to 128-bit. It performs significantly worse than the 12GB model though thanks to the resulting cut in bandwidth.

I'm setting the prices high in my mind, but nothing stopping them from charging more than they should for the 1st 3-6 months... and see if enough people bite or not, before reacting.

Then again depends what we find out about the upcoming cards, may be very little reason to upgrade to one outside of a few select titles, unless a ton more suddenly get ray and path tracing coinciding with the launch...
