AMD: Navi Speculation, Rumours and Discussion [2019-2020]

It depends on which is the perf/W starting point. Was it the 5700XT? Was it the 5700? Or the 5600XT? Or the 5600M with HBM made for Apple (2060 Mobile level in 50W)? Too many variables to have a definitive picture. Someone is saying AMD is targetting a 275W cards, now it must be seen, if it's true or not.

 

It's fmax card to fmax card.
Just an extension of their previous V64 vs 5700XT graph.

 

But IIRC the 5700XT was "a little" over fmax or am I wrong?

 

No it's just uncomfortably close to

 

Hm... I don't know. Do we have any estimates for how much HBM2 runs for nowadays?

I am still surprised that AMD haven't spun other SKUs (mobile or otherwise) based on the Apple Navi 12+HBM config. That thing is perf/watt beast.

I owned both R600 (2900 XT) and Hawaii (290X). Those things have a hot warm place in my heart.

 

So the only hilarious outcome I can see is if AMD is actually targeting using most of the perf/watt improvements to drive performance, rather than power savings and this ends up being more than a 350W card.

Edit: 300% 5700xt at 450W incoming.

 

Oh it's more funny than that.

I think Sapphire should try if just for kicks.

You'll hear the same perf target a few more times since N22/23/24 are AIB-only launches.

 

275W for just above 3070 performance sounds bad even for N22, though. Hopefully, he's conflating N21's TBP and N22's performance, lol.

 

It's odd that no one's leaking AMD's nextgen mobile plans.

Yeah.
Because it's not real.
There's a reason for no non-reference N21s anywhere close to launch.

No shit.
Anyone with half a brain still functional looked at XSX power rails, the usual MS OP ratios for PSUs, RNR SoC power at ~3.6GHz and thought really hard.

 

Dual stack HBM2E for 800-900GB/s from AMD's long time partner-in-HBM SK Hynix seems like a very strong possibility for Navi 21 at the moment.
We're also starting to see anti-HBM FUD around (it's too expensive for a $600 card because of stuff!), which further reinforces that possibility IMO.

 

I don't think anyone can ship 3.2Gbps HBM yet because otherwise we'd see it on A100 and MI100.

Yeah and backdrill PCBs with infernal custom memory aren't.
:^)
Some people have the weirdest double standards.

 

Maybe this is why NVidia is "scared"?

NVidia has had plenty of time to peek into every corner of its performance profile.

I'm keeping my fingers crossed it's $1000. Maybe $1200.

 

Mobile is over.
N22@90W locked is just warcrimes.

It's between AMD and Apple now.

I think they'll drop the top SKU at $999 for nice round number and the headlines it may generate.

 

The 80 CU's.... (not me)
but it is getting some discussion on Chiphell https://www.chiphell.com/forum.php?mod=viewthread&tid=2257320&extra=page=1&filter=typeid&typeid=223

 

Funne and their marketing () is shitlording.

and the teaser is a big nothing

Something Big is Coming To The AMD Battle Arena!

 

well my posts posted multiple times

Here is something new


""Correction, there's no 8GB model (afaik). This was lost in translation as we were also discussing how AMD will probably promote Big Navi having 16GB versus the 3070's 8GBs. Sorry for the confusion! - btw source also said an HBM version for consumer is not planned "

 

NVidia killed a load of techtubers and twitteratti with GA102. AMD appears to be cleaning up the dregs.

 

Coprocessor my ass.

They're knifing friends in AIB places, yeah.
