[WCCFTech] AMD Dual GPU ‘Hawaii-XT’ Card Codenamed ‘Vesuvius

[OCGuy]

I think this one is legit from them. I think we're going to see the first reference VC that has a closed loop for cooling.

So worst reference cooler in recent memory for the single, to the best for the dual?


We won't see a dual card until 20nm.

 

[Haserath]

Vesuvius, eh?
Might as well call your main board Pompeii then.
I suppose there is 5% more performance in dissipating the heat across twice the area, and thus getting slightly more efficient cooling and therefore less temperature and higher efficiency. Because more power isn't available, unless they go ahead and ignore the PCI standards, and make this a 350-400W card. Might be best to make it 4-slot and put a big tower cooler on there...

Lower clocks and lower volts. A 300W card could deliver 60% more performance over a 290X.

There is still plenty of room for them to deliver performance. The 290X averages 240W in games and peaks at 280W. The standard was ignored for the 6990. If they deliver the card, they'll deliver it with performance at any cost...

Curious how quadfire would do with two of these.

Ironically, these volcanic islands chips are really going to be living up the their names... Probably should have called this chip Tinakulahttp://www.volcanolive.com/tinakula.html instead

Doesn't need to be spec for OEM compatibility. Just a limited run special ed, with a water block on it. Full bown 3x 8pin connectors, ample room for massive OC. Will sell out ASAP if they do it. There's already a lot of enthusiasts putting R290/X on water, this is nothing out of the ordinary.

Ok, let the speculation begin:

---------Pin Power Clocks Noise SPs Noise Heat 1080p 1560p EyeF 4k

R9290x2: 3x8 425w ?/900 =290X 2816 50Db 85-90 100% 100% 100% 100%

GTX790: 3x8 400w Titan's =680 2880 44Db 75-80 104% 98% 94% 92%

I will definitely be in the market for one or two of these (assuming my 1300W PSU can power two plus the rest of my rig which I'm starting to doubt). Just finishing the CPU bit of the new build and waiting for aftermarket coolers for the 290 to arrive BUT this looks very interesting.

I'm sorry but at 300W for one card I seriously doubt they will even try for a dual.

Power use didn't stop them from coming up with FX9590 and 7990. So I woudn't put it past them.

This time it's different, the dies are bigger and VRAM is bigger. The only way they make a 2-GPU 290X is if they push the power envelope to 400W+. It just doesn't seem worth it with 20 nm scheduled for a year from now.

I dont want to throw my chips too much into this Rumor but given their history I wouldn't put it past them. Even if its a limited run of cards.
Also we all know that putting Wattage aside with even remotely non reference cooling the cards keep cool fine. ( see overclockers website forums).
I have no doubt that cooling wise its doable.

Why do they keep calling it an overheating problem. It's the design spec to run at that temp from the factory.

It is designed to throttle at that temp. "The factory" had no idea what the reference cooling design would be when engineering the chip.

They don't pick a throttle temp and then engineer the chip around it.

Actually, you can. The ref design basically leaves no performance on the table, whether its power use or temps. Also it doesn't throttle, I don't know how you can say it throttles if it is still boosting even when it hits 95c. Throttling would be if it goes below the base clock, it doesn't do that.

You can pick a point and have it stop boosting when it hits that temp. Just like GPU boost and Intel's Turbo.

The way powertune is works sounds to me like the knew exactly how much cooling they had available.

There is no advertised base clock. The card absolutely throttles. "Stopping boosting" is semantics, and I hope it is sarcasm.

The base clock is 727Mhz while the boost clock is the max clock it will reach.

Nvidia does it differently by advertising a base and minimum boost clock then has the clock go as high as possible with no set maximum.

Technically speaking, anything above 727Mhz is extra.

Wrong on all accounts, but that is for a different thread I guess.

So if there is no base clock how is it throttling? semantics or not. You are incorrect sir.
