Synapse Design is a company responsible for AMD’s chip floor designs. Synapse recently announced new GPU tapeouts, including two 28HPM silicons (this was discovered at Anandtech forums).
The first one is relatively large chip, 500 sq.mm+. The 28HPM is as powerful as 20nm SoC architecture, so this might be the new Radeon flagship GPU. This processor would run at 1GHz frequency, and according to the source, it will not feature HBM (High-Bandwidth-Memory).
The second GPU is 350sq.mm+ silicon. There is a good chance that this particular chip is actually Tonga. We did confirm that Tonga is almost as big as Tahiti, 350sq.mm sound reasonable.

This is all for now. We are currently expecting more information about Tonga, mass production starts in two weeks. We should see more leaks somewhere in August, so stay tunned.

Extremely ballsy move from AMD/ATI to go back to giant monolithic dies. It's about time they brought back their A game: go big or go home.

But honestly since they're both stuck on 28nm, there's no other option but to go big.

Totally Agree - will help put price pressure on Nvidia big dies too

 

[jackstar7]

If they can put together a stock cooler that can handle it, then I am ready to buy when this hits the shelves.

It would be epic if AMD decided to (1) bifurcate their GPUs into non-compute heavy and compute heavy for professional markets (2) ditch the inefficient blower type coolers in favour of open air cooled goodness, or even better a 120mm AIO LC.

Imagine a 500mm2 AMD gaming chip without being dragged by DP compute with a 450-600W heatpipe cooler with 3 fans, similar to the Gigabyte Windforce 3X or Sapphire Tri-X?

It's probably too expensive for AMD to design 2 separate chips by removing DP from their 390X at this time since their professional dGPU market share is still too small to be able to fund R&D for separate gaming and professional dies but one can hope. However, the move to an open-air cooler should be seriously considered. Otherwise, without liquid cooling, I am curious to know how AMD will be able to cope with the power consumption of a 500mm2 die (if true).

NV released 7900GTX with an open air cooler and it was a good one even for way back in the days.

Despite the praise NV's reference coolers get, they are still far inferior compared to an excellent open air cooler, we are talking a 19-20C difference.

Titan Black Reference = automatically regulated via BIOS = 87C at 3420 rpm, maxed out manually = 77C at 4280 rpm
vs.
Gigabyte Windforce 3X installed on the same card = automatically regulated via BIOS = 78C at 2040 rpm, maxed out manually = 58C at 4271 rpm

I think AMD really needs to think of going open air cooler since it's a win win for temperature and noise levels and a gamer with a modern case should have no problems coping with a 250W TDP open air GPU:

If the stock cooler is decent, this thing could be competitive.

No doubt the open air would get the job done better, but I remember reading something a while back where AMD was asked about this directly and they basically said they have to use blowers on the reference cards due to OEM requirements

I believe I read that too in one of the AT reviews. I wonder if going 120mm AIO LC would pose a problem though since most cases should have a rear exhaust opening for the radiator. A single 120mm is good enough for 295X. It would do wonders for a 500mm2 AMD single chip.

Absolutely agree. I think that is the route they should take.

 

[Attic]

I like leaving the improved cooler versions to folks like Sapphire, Gigabyte, not sure the term for these guys.

I like the options this generates and it drives competitiveness for cooler efficiency. Sapphire Tri-X is amazing and somehow the PCS+ cooler on the 290/x still doesn't get the respect it deserves (as good/better than tri-x for temps vs rpms)

I'm really impressed with the AIO hybrid cooler for the 295x2. I could see that being the option. But there still needs to be straight forward rear exhaust setup and who better to do this than AMD, they just need to improve it.

That sounds familiar as well. I doubt AMD would go AIO for higher volume card. If open air cards are out of the equation, then designing a better blower card would be their best bet. After their lack luster Hawaii reference cooler I think this would be an opportune time for them to instill more confidence in their reference design. If Nvidia can do it, then there is no reason why AMD can't.

While the reference EE cooler Nvidia uses on their GK110 cards doesn't leave a whole lot of thermal headroom for high overclocks, it's still an amazing reference cooler overall. As subjective as it may seem, it's really a cooler you have to experience to appreciate.

 

[Haserath]

What AMD needs to do is fix their cut outs and port placement on the back of their blowers. Move the Dvi ports like Nvidia and switch to this:

If only Dvi could get phased out, such massive connectors for what it can do.

AMD still needs to put some effort into improving their reference coolers. They got hammered in reviews because of it, and that leaves a lasting impression. People still post here thinking that Hawaii is a power-hungry volcano, and while it is not the most energy-efficient design, better cooling helps it out a lot.

 

[BFG10K]

You're missing one critical point: open-air fails for multi-GPU because the top card overheats. The 7900GTX's TDP was just 84W so it didn't really matter.

Neither vendor will release a 300W / 500mm2 flagship with a cooling solution that doesn't allow them to be combined.

 

[PliotronX]

[alcoholbob]

If AMD releases this 500mm die soon after gm204 nvidias lineup could be quickly marginalized until they have titan 2/gm200 ready.

 

[master_shake_]

as unpopular as it seems i would honestly like to see high end cards come with a clc as a stock cooler.

think of the overclocking potential.

Bleh, I wouldn't want that at all. If it's got a 120mm fan on it, I would also have to get an adapter to mount it in my case which only has 140mm fan mounts. Also, in terms of aesthetics, IMHO, those things are ugly as sin with that thing dangling off.

Give me a great air cooled card. I get decent temps with a pair of GTX 780 SC ACX on a Z77 Sabertooth board.

Edit: I do see your reasoning though, lol.

The problem is that open air coolers are terrible for multi-GPU. :/

 

[SlickR12345]

Great, we are likely going to see 2 high end chips from it and then we'll have a mid range line probably later.

It's the 5800 ultra.

[Vesku]

Highly doubt AMD will have two separate monolithic dies, one gaming one compute, not even Nvidia does that. Could happen with the smaller die I suppose but it would go against AMD's heterogeneous compute strategy.

Stop presenting your speculation as fact. That's a bad thing to do, but you do it all the time. Do you even understand the difference?
