Graphics 22/23 GPU Thread - RTX4000 AND RX7000 Series

Now, we wait for review NDAs to expire...

 

Really interested in how well MCM works here, essentially Crossfire on package, hopefully compatibility is no issue, nice price, sounds like it's going to come in under a 4090 in performance.

 

I would assume preventing the massive inherent problems of crossfire / sli is the reason that the main part of the GPU is still very much monolithic with only some specific parts being moved to chiplets.

 

Ah I see, not had a chance to sit and watch it yet but it seems it is GPU die and cache dies, so likely no multigpu issues as it is one GPU, I thought the MCM approach was going to be multiple GPU die.

Should they do a dual GCD then it would be Crossfire like, I wonder if this approach will ever be taken.

 

Yeah its basically one GPU die + multiple cache and memory controller dies.

 

I see the reference models have no venting in the IO plate. So they dump ALL of their heat inside the chassis?!

I'm assuming/hoping these are just render oopsies.

[edit] nope, no oopsies - deffo a solid rear plate.

 

How much energy _really_ escapes via the IO plate? It seems better to allow some than none, but I have been skeptical about how much of a difference it makes. If it were a large difference, surely every card's fin layout would be lengthwise rather than widthwise, as they'd score better temps and more units sold?

 

Personally, I'm a fan (har har) of lengthwise fin layout. It makes possible for better passive cooling using a fan at the other end, it also blows a lot of hot air directly out of rear IO, finally it doesn't heat up M.2 drives by blowing heated air over it, yet there will still be some air from edge of GPU fans over the M.2 drives.

nVidia FE method also works well. Clear paths for all the air to flow.

There's mention that the 7900 ref cards have temperature probes near one of intake fan. Suggesting it will read out card's ambient temperature. So the concern that all the heat will be trapped in a hot-box has been considered by AMD......... one would hope.

 

This is not AMD's big card. Not yet.

 

Bad news for wallets - Both Scan & Overclockers have 4090 AIB cards in stock right now!
Worse news - £1825-2180

 

The AMDs should cost half that. I say should, because scalp+gouge=BS, but yeah....

 

i think $999 equates to £1100 once vat and other bollockry is factored in...

So I'd expect the AMD pleb spec model to be that and partner cards to be £1200+

 

Yes. At least that.

However, that is still cheaper than the 4080, and it should be a good chunk faster.

 

3DMARK just leaked. They are 50% faster than a 3080, whilst being 100% more expensive.

 

Makes me sad to see EVGA are gone from the game, that 4090 is a thing of beauty.

 

Jay got a working one.

 

If you put a GPU like that, in a case without adequate airflow, you're an idiot.
