AMD High Bandwidth Memory Official Slides

[CommandMan7]

The way things are looking, the 300 series will be a lot cooler stock due to low voltage but will run into a thermal wall when under overclocks due to less surface area.

[captain cactus]

I'll be hyped. A bit.

[wpirobotbuilder]

But will they actually make something high end with this, or just do something with dinky apu's?

The 390x is supposedly coming with this memory.

 

If I don't see this resulting in a triple-GPU card, I'll be sorely disappointed and ready to riot.

 

Out with the GDDR space-hog, in with more GPUs on the same PCB!

Agreed. Think of the advantages for HPC by having the same memory in less space, and more GPUs in the same board. nVidia can't do more than two high-end GPUs in a two-slot form factor, even in their Grid cards.

I wonder what kind of performance it will offer over non HBM cards.

[Facety]

Hmmm.....interesting....

 

I want to see the real world performance difference between GDDR5 and HBM and how it 'stacks up', eh eh   ....ok I'm done

[Guest Kloaked]

You're out of luck.

@That Norwegian Guy

 

The card wasn't released. GG.

[mvitkun]

You didn't say released lol, you said

If there's ^{(contraction of there is)} ever a triple-GPU card

and the EAH3850 X3 Trinity was, and therefore still is.

But if you want to back out and show us how little your word is worth then by all means go for it.

Since you're going to keep going with it, you're taking this out of context to begin with.

I could have been more specific, but I wasn't so your conclusion could be drawn, but I was more referring to what OP and Norwegian Guy was talking about, which is the contents in the OP.

Okay fine.

3DFX's Voodoo line had dual gpu cards, triple gpu cards, and even quad gpu cards.

And those were all released.

You're not understanding.

I was responding to a comment that was directed at the OP which are about the new Radeon cards.

[Syfes]

Nice, maybe soon they'll be able to fit something more powerful than the R7 250 on a low profile card. Something in the same category as an R9 270x would be nice. Somehow I doubt it, unless they can produce a chip that's much less power hungry, but still now they should be able to fit it on the PCB at least

[mvitkun]

So with the radeon triple gpu card you weasel out by saying it wasn't released ^{and we should all know you meant a card that was released because} , and with the Voodoo triple gpu card you weasel out by saying you specifically meant radeon.

[Briggsy]

The question is if 390 series will have delta compression, like NVidia's 900 series. In that case, 4GB is more like 5GB on a 290 series. Either way, we will see 8GB versions, if people can wait/wants to pay more for it.

 

GCN 1.2 has lossless delta compression as well, same as Maxwell's. AMD first introduced it with the R9 285.

Exactly, but will they dedicate the transistors to it, now that bandwidth is not in any way, an issue? I don't know. We will see next month

Do you even context? I've explained it twice now.

I didn't say "If there was ever", I said "If there's (there is, in case you get that confused too) ever" as in what subject we're talking about in the OP.

So, if there is a triple Radeon GPU that comes out, such as a 395x3 or whatever they decide to call it, then I'll do it. I'm not weaseling out as you say.

New Voodoo 5 6000 anyone? tiny HBM package could allow four GPUs per PCB AMD pls. 

[Briggsy]

I don't think it's something they can disable per say, and if they could it would cost money to redesign a chip to have less efficient compression.

[Blackie Sheen]

Do you think they need the water cooling due to the fact of less surface area for cooling due to the inherent design of the Hbm?

Manufacturers could still make longer pcb simply to hold a longer cooler without having it completely used

That looks gigantic

Sadly it was never made mainstream. Some test samples were made and only a few survive. The bridge chip died to ESD which killed a lot of them.

They are unique as a concept, but they wouldn't have even gotten DirectX 7 support when Nvidia and Ati cards of the time had it, so they wouldn't have sold anyway.

[RexinOridle]

Those stacks look like they will have some cooling issues.

If only Nvidia did the full takeover to keep them alive. But i don't think Nvidia would have kept that project.

 

All it take is one AIB partner and quad CrossFire on one card will be amazing and completely unnecessary.

it's still a higher SA to Volume ratio, so cooling should be easier.

Memory chips running at such low base clocks shouldn't get warm
