Wow. Yeah. That's as huge as I would expect it to be. And to think this is what a high-end card used to look like:

But I would still bet it will be up to hardware companies to decide whether to go beyond a stock 4 GB memory.

As for power consumption, well, we have PowerTune to more or less keep things under the 300W PCI-e supports, so no wonder it doesn't go that higher.

@haxxiy: All the 290X are/were big. VRAM chips take a lot of space, and with the GPu being so hot, they need big ass coolers with as many fans as possible

Luckily HMB will make them smaller... but that will bring other problems.

I guess I just didn't expect them to look like Titans or Quadros. Even dual GPUs used to be smaller...

Either way, 4 GB seems to have  been confirmed now - http://arstechnica.com/information-technology/2015/05/amd-confirms-4gb-limit-for-first-hbm-graphics-card/ - I'm not sure that's too nice since the top cards are supposedly $849.

Oh, AMD. Why do you do that to me? .-.

4GB will be bad news.

Who's going to buy a $849 4GB GPU when, for a little more, you can buy a card just as fast but with three times more memory and the extra eye candy bits that Nvidia brings to the table?

If true, AMD's 3x0 series will be DOA.

Yeah I was just coming in to post that info : http://www.fudzilla.com/news/graphics/37790-amd-fiji-aims-at-849-retail-price

It's going to be a disaster. I was excited to see that an 8GB card was on cue, but of course it's just a CF on a card deal, so games can only use 4GB :(

The stupid thing about this is that a pair of 970s or 290s will absolutely murder it for cheaper. And a pair of 8GB 290s will slaughter a 390 in eyefinity/4K.

So the market for this 390X is :

(1)- People with a ton of $$ that only want a single GPU (dual top-end GPUs are only useful for beyond 1080/eyefinity setups, and 4GB limit would hammer those configs with 2015+ games, 6GB and beyond is minimal now for high end)

(2)- People who are stuck on a single 1080p display, and who are willing to make compromises on settings to stay under 4GB in the near future (several games noted on GAF are pushing 4GB+ @ 1080P already!!)

(3)- Uneducated comsumers?

Hoping for the best from AMD. I am getting a 3440x1440 monitor soon, and will get a new card sometime to go with it. No rush on the card though.

@Arkaign: To be honest, that $849 price tag is still a rumor, nothing more, so we should take that with a pinch of salt.

But yes, it looks like AMD sould have gone for 8GB GDDR5. They could have launched the card a lot earlier and also cheaper.

Oh, well. I think I'll wait an extra year to upgrade, or pick one of the 8GB Hawaii based cards if they are worth it .

So no 8GB killer single cards from AMD this year? Is this confirmed or only rumors? If it turns out to be true; I'll be better off just getting the baddest version of the GTX980, which will go down in price quite a bit when these new AMD cards release.

Dammit.

^So far they are only rumors, like everything involved in the new cards.

But if you go to any tech site, you'll see that since yesterday most of them have articles about AMD and HMB, and most of them talk about 4GB. So while so far it's only a rumor, all signs point to that direction.

That's a real letdown then, I was ready for 8GB!

It could be that at least one of these cards beats the 980 on performance though, I'm going to need more info on pricing before I make my decision. Even though AMD are always great on pricing; the increased noise, heat and driver issues might not be worth the savings in the end.
