Are Nvidia done with dual GPUs?

Seeing as they tend to offer serious bang for your buck, and knowing how Nv like to milk it, is it highly unlikely we'll ever see a dual GPU from them again?

Edit: I don't count the Titan Z abomination, that's just not even a real world product from either a performance or VFM point of view.
 
That's what I thought too. Dual GPU on one board cards are usually lower clocked and worse performing, more expensive, and run hotter than buying 2 separate ones. They still however have exactly the same issues as any SLI or crossfire setup, so are a total waste of time, unless you only have one pcie slot.

Dual GPU's normal cost more or at lest the same amount as buying two single GPU's....

How much would it cost to buy two 290X + AIOs + brackets to mount them, compared with the £500 of a 295X2?

YOUR BASKET
2 x MSI Radeon R9 290X LE Gaming Edition 4096MB GDDR5 PCI-Express Graphics Card £239.99 (£479.98)
2 x OcUK Tech Labs 120mm Kraken Extreme VGA Cooling Upgrade Bundle - Standard - Black Shroud £70.27 (£140.54)
Total : £630.12 (includes shipping : £8.00).



Vs £500, not to mention the space and hassle needed to mount two seperate AIOs.
 
So running two 290Xs next to each other on stock cooling is a good idea? There's a guy on here posting about his single card hitting 91c and it's only bloody April, lol.

Some of us aren't deaf, there's no way I'd be running two 290s on stock coolers.
 
shake your head as much as you like, the basic facts are that two air cooled 290s don't offer the same cooling or audible performance as a 295X2, otherwise you're just comparing apples with oranges.

Like for like is the name of the game, two 290s may well be cheaper, but how much would I have to spend on top to get the rest of the 295x2 performance?
 
I think with the way an HBM gpu will operate, very small or simple pcb, effectively more area for the heatsink. AMD would have a massive advantage when it came to a dual gpu card in size. One thing I'm not sure on is if AMD could manage to use a secondary interposer to stick two gpus together to get on die communication, saving power and reducing latency which should bring a lot of benefits.

If they can do the latter it's likely anything Nvidia introduced would be somewhat embarrassed by what AMD could produce this gen. Even just on card size and design options AMD will have a lot more leeway than nvidia.

Another very interesting option when it comes to interposers and HSA compatibility is if they could design the gpu's to stick together and actively work as a single gpu with a single memory pool.
 
What exactly are the options for interposers, can you place them on the back of the PCB or anything? As I understand it they are essentially a giant but simple integrated circuit, so I'm thinking if RAM modules can be placed there then why not.
