Or.... they know something about the ventilation and its efficiency that we don't...

Yeah there is that, but I am not sure what the downside of exhausting some of the hot air out of the back of the case would cause.

Yeah I am not sure why they have done that, hopefully it's just a testbed and they correct it for the real card.

There is no rear exhaust because the way the fins are stacked lol.

what node is it going to be on?

7nm? TSMC process, same as 5700xt. but it has to be 100% quicker.

Thought you were comparing to Nvidia. The 5700xt is only a 10 billion transistor gpu. In the scale of things AMD could triple that and still have a smaller gpu die than Nvidia. You really shouldn't use the 5700xt as an example of whats possible on 7nm at tsmc. To get a better look at what's truly possible have a look at Nvidia's Ga100 chip which has nearly twice the transistors of a 3080 chip. Now AMD will go no where near ga100 but there is so much space for them to move into it's hard to believe they can't bring the heat if they want to.

So those screws on the left and right are real. This might actually be HBM based.

It might be,but RGT says its a 256 bit memory bus with 128MB of cache. It would sound risky if true.

Yeah, that's not making sense. AMD hasn't provided any official specs yet so we will have to wait and see what the Uarch for this 6900 actual is.

Due to the cost of HBM I can't see them doing that for a 3080 competitor...now if HBM got them on the 3090's tail it could justify going a bit over the 3080 cost (but not too much)

Maybe there are two models using the same GPU - one using GDDR6 and the other HBM2??

Very possible. It's not clear how many skus AMD have right now and when they will be released. But from all the rumors so far I count 4 of them.

It makes me wonder whether AMD are just releasing conflicting rumours on purpose??

Hope this is an early mock up. Not liking the lack of rear ventilation.

The ventilation is where it needs to be, the hole around the gpu. Might well have an aluminium backplate to draw heat away from other components.

I believe so, they've done it before. And it's been said they are doing it now.
Now where the performance will actually land is anyone's guess. There are 2 possibilities that's been floated "rumored". Is that these cards are indeed powerful.
Or
They have these next gen games so well optimized for RDNA 2 that even a potato will shine.

It will be interesting to see how things develop.

So far there is little to give him credibility - his "exclusive" leaks have been way wide of the mark and his more correct information has been presented after the fact when it has broken first by other sources.

That's pretty much the impression I got. To me, it sounds like he just tells people what they want to hear, says the info is from a reliable source, then maybe backtracks slightly.

Usually when people say info is from a source that has been 'right before' with no other details, it's highly dubious.

Yet, you here the phrase again and again.

So who thinks big navi can get close to the 3080 now that we know how it performs? What kind of specs are we talking to achieve that?

Good looking :cool:

Genuinely no idea.

The silence is deafening

No, no, I was comparing it to AMD latest GPU aka 5700XT.

Here are the RAW facts ladies and gents:

Let me brake it down for you lot.

Big NAVI needs to be 100% quicker than 5700XT in 4k to LVL with 3080. FACT
( 4K its where this will be fought. not 1080p 1440p )

Right. So.

Big Navi has to be 100% quicker that "fine wine" 5700xt just to LVL. 3080 never mind beat it.
Big Navi has to be 90% quicker that "fine wine" Radeon VII just to LVL 3080.

Both Radeon and 5700xt are already on 7nm TSCM

Which let me tell you right now is a pipe dream. Sorry lads. Aint going to happen.

I tell you what will, probably happen.
We will get a bastardised 60CU from Xbox with RDNA2.
Improved efficency + tweaked Mhz, and now you are probably looking at a 50% uplift over 5700XT.
Which should put us in and around 2080TI/3070 with 16gb of ram, good cooler and now you are talking.

Thats a good card, price it right. :=)

And i just might be interested.

Just dont paper launch that succa on OCT 28 AMD>

There is a rumour (of course) that AMD are "leaking" conflicting information in order to track down where their leaks are coming from.

I expect 120-130% higher performance from RX 6900 XT than the mid-range RX 5700 XT.

for a 80CU it will probably be 150% with 220W
