RTX 3080

[starsarethebest9]

So I am thinking getting the RTX 3080 i have the Corsair AX1000 will that power supply work with the RTX 12 pin that is required? 

[FloRolf]

yes. There will be adapters from dual 8pin to 12pin.

Also, custom designs are supposed to ship with dual 8pins on the card instead.

Yes, adapters are included. From the other thread:

to everyone who is wondering what cables you will need , it has been confirmed that it will come with an adapter and it will need 2 8 pin connectors

The 3080 should ship with an adapter in the box. 

Corsair will probably manufacture a new lead for their PSU's that you might be able to purchase at some point.

Thank you both.

Ah good, strongly thinking of a 3070 here.  Be more than enough performance for me at 1440p 165hz. 

 

Main concern was my EVGA G3 650.

No NVLink for 3080 founders edition? Is that correct? Could other manufacturers still provide NVLink?

I'm assuming that since I have a mini-ITX case (NZXT H1), I need to avoid the FE style cooler?  Theres like half an inch between the GPU and the back of the motherboard.

Nope, only 3090. Multi-GPU for gaming is dead.

Was planning on using it for deep learning workstations. Guess I'll have to go with multi 3090 then.

Ah I see. Well, that use case is what the 3090 is aimed for as a Titan-esque card from my understanding (although I understand the massive price gap makes it less attractive perhaps).

If I can get 4x Titan for $1500 a piece damn was it worth the wait ...

You don't need nvlink to do multi gpu deep learning.

How do you pool memory otherwise?

Depending on what you're doing, data-parallelism is pretty painless and achieves pretty similar results. Otherwise, there's no actual "memory pooling" happening. Trying to fit a batch size bigger than a single card allows would lead to a OOM error. You can read about it here (take a look at the comments too!).

 

You might also want to wait for the RDNA2 releases to see if nvidia releases a Super/Ti variant, maybe those will have one or two nvlink bricks, along with more vram.

I may not have the luxury to wait as the investment has a given timeline. But thank you kindly for the link I am reading it now.
