Also, easy Xbox 360 ports didn't help the WiiU. Only selling decent ammounts of 3rd party software will help in getting support. The PS3 did that masterfully with an NVIDIA GPU.

I had owned both NVIDIA and AMD gpus, and I'm quite neutral to these two companies, but the AMD love is getting silly. Both have their pros and cons, and which is the better choice for the NX will depend entirely on performance per watt and price.

Wow. And you accused me of being misleading? If any of this was truth, AMD would be dominating the mobile market. They aren't, so what makes you think they can? Where is that amazing AMD mobile chip?

You can say anything about NVIDIA but at least they have something tangible out there, on the mobile space. We can know that what NVIDIA has is real and works. The NX can't run on wishful thinking.

It depends on which tasks are done but yes, HSA coded software can be many many times faster and use much less power.

Its why ARM,Qualcomm,Samsung,MediaTek,Imagination, Texas instruments... ect are all Key founders in support of it.

They see that is the future of programming for mobile phones (as a way to lower power consumption).

AMD dont have a mobile chip line, but I think they could make one equal to a whatever tegra chip nivida has, if they tried.

Ok, thank you for admitting that. Know that HSA might sound like today's snake oil just like tesselation did when DX 11 came out. And back then AMD also seemed to had all the advantages in the world because of their longtime tesselation investment.  That was the era of their 5000's series and they were unstopable. Until Nvidia stopped them with their far superior tesselation implementation.

HSA is great not because of the companies that are involved, but because of the talent that created it. And a huge part of that talent, has been working in Nvidia for a while now. Pascal just had their first meaningful DX12 win in Rise of the Tomb Raider benchmarks. Nothing is set in stone.

Also, a AMD chip competing in the mobile space? I'll believe it when I see it.

Actually Tegra should have the edge over an AMD ARM core, nVidia has the Big.SUPER A57+Denver 2 core layouts, Denver has been one of nVidia's pet projects.

Whilst I agree that HSA is as how you put it "Snake oil" salesmanship. (Many forum posters here thought it was the second coming that would make the PS4 superior to the PC. - Never happened.)
Besides, HSA has evolved now, it's allot more flexible and superior to the PS4's implementation on the PC, you can even have multiple memory pools now.

Tessellation actually has tangible real-world benefits that we are seeing used extensively in games today and have seen those benefits since Frostbite started gaining ground with Battlefield 3 and Cry Engine with Crysis 2.
You can even go farther back to the PS2/Gamecube/Original Xbox era and see Tessellation being tested in earlier games on the PC.

Take a look at a game like Dragon Age: Inquisition, walk up a hilly slope on one the rainy maps, the difference Tessellation has made turning the flat plain surfaces into surfaces with bumps and definition is not something to be understated.

As for AMD competing in the mobile space... They were decently competitive with their Cat cores verses Atom, but they have stagnated for far to long.

Adreno is also derived from AMD (Well, ATI if you wish to get technical), In-fact the word "Adreno" is a play on the word "Radeon". (Just re-arrange the letters.)
So AMD does have experience in building ultra-low powered GPU designs.
And Graphics Core Next has been shown that a moderately equipped GPU can scale down to 4.5 watts, and that was on 28nm.

I guess the way I worded it seemed to imply that is imposible for AMD to compete. I don't think is imposible, just almost.

As for AMD competing with atom, I'm actually using a intel based phone and one thing I can say for sure, is that it sucks.

I think AMD screwed up and the PS4 Slim was the 3rd console win.

I've used Atom powered Android Tablets.
It does have some detractors.

Medfield when it first dropped was actually competitive.

We've been over this already. The PS4 Slim isn't a new design. It's a die shrink. 

Some of the content here is absolutely painful to read with desperate points made at both sides ...
