Supposedly the new Drivers fix the issues the 780/780ti users were having, not tested it yet though.

It's beyond that, lots of users are having a lot of crashes Nvidia side with the Witcher 3 specific drivers. People are giving AMD grief for not having a Witcher 3 specific driver within a week of launch but the actual driver already out ran Witcher flawlessly. Nvidia have had a Witcher 3 specific driver, a couple I believe and loads of Nvidia users have had a significant number of crashes... yet AMD get accused of having poor drivers everywhere and every other post is about how brilliant Nvidia drivers are.

Nvidia has a history of ultra quick post launch drivers which aren't entirely stable and need several releases. AMD had an 'old' driver which gave great performance on the 290x and other cards from the get go, it's also solid and has been working for a long time.

The thing that irks people is that Nvidia guys are running around every thread screaming about bad drivers while the 99% that don't run xfire have had great performance in pretty much all but the car game that I can't remember the name of. This is while Nvidia ignored for months and months much worse performance issues with Kepler cards over the release of multiple games.

AMD don't have a driver for a week, though single card worked absolutely perfectly from launch anyway, Nvidia guys hit AMD in every other post about crap drivers. Nvidia finally address a massive problem for Kepler users(there are more kepler users than Maxwell by a large margin) after MONTHS, having ignored those users with multiple very long threads on their own forums and it's "how great is Nvidia support, awesome", it's nothing short of ridiculous.

It doesn't need to be.

If you take the 285 and double its Shader count to 3592, give it 7/10 scaling.
What you end up with is a 918Mhz card 30% faster than 1000Mhz 290X @ about 380 Watts (and that's with 32 Memory IC's instead of the 16 it would have, take another 40 Watts off that)
That would put it right between a 980 and a 980TI

Now if a GDDR5 3592 Shader 918Mhz Tonga GPU can manage that how is it that a 4096 Shader 1050Mhz HBM GPU cannot better it?

So either AMD have gone backwards with HBM or someones trolling.

It's 3584 or 4096 shaders and it was my theory but with one memory controller and singke die, on overclockers months before anyone on the net discussed or even thought about it. I'd like to see if it becomes a reality but not on 28nm.

IMO one can't include the HBM chips as part of the GPU die, whatever way one looks at it they are not, some people will, its almost looks like they ^^^ want to.

The GDD5 interface in Hawaii is huge, its bigger than anyother 28nm GPU.

They don't need that in Fiji and could do away with it, it would bring the 438mm2 die size down about 25%, the power consumption would also come down quite a bit.

They would probably need to grow a HBM Hawaii by about ~25% to accommodate 4096 Shaders.

So it might be about 550mm2 in size with the GDDR5 interface removed, the same size as GK110.

Yeah and then there's the gf 28shp. Vs the tsmc 28nm too.
Still too big and juicy for air, and rescaling would limit clocks on air.
Hence I'm not happy with it on 28nm, as in our previous discussion about it.
But performance of cf 285 3584 with a weedy 256 bus is still quite strong.

It's speculation but come on amd made tonga for a reason,
Or my hunch is very very wrong.

According to a discussion on another forum 28SHP may not even exist. Synapse leak is 28HPM from TSMC btw.

is there a live stream from AMD @ computex tonight?

They have streamed previous ones but apparently not this. Anandtech and other sites have live blogged Intel and Asus, but not planning to do AMD for some reason...

wow just wow.

AMD is a trainwreck waiting to happen right now. That teaser posted above is beyond awful
