For its part, Nvidia will combine its Maxwell graphics core with its first 64-bit ARM core to create Parker in 2015. It will be made in a FinFET process which by then should be readily available as a sort of second-generation 20-nm node from Globalfoundries and TSMC.
Parker will certainly power smartphones and tablets as a Tegra 6. What’s less clear is whether it will have a life in notebooks, desktops or servers.
Microsoft’s WindowsRT for ARM—aimed at tablets--has failed to gain significant traction and badly needs a makeover. Until it gains traction in tablets, Microsoft is not likely to try to drive it into notebooks and desktops. And we are still waiting to hear anything about Windows Server for ARM.
Meanwhile, Google has been mum on any plans for Android in notebooks or desktops. No surprise really--it is only now well positioned for a dominant role in smartphones and tablets.
Google has experimented with a slimmer Chrome OS layer that essentially puts a browser on a cloud-based laptop client. The effort, now in a second generation, has failed to gain much traction.
But, interestingly, the Google exec (Sundar Pichai) who ran the Chrome OS initiative was put in charge of a merged Chrome OS and Android group. Android founder Andy Rubin left the team to explore other opportunities, as the old euphemism goes.
One more wrinkle: Nvidia said in 2015 it will also roll out Volta, a next generation graphics processor using stacked memory with through silicon vias. It did not say if it will use a 2.5-D technology pioneered by Xilinx that lays memory and graphics cores next to each other on a common substrate or actually stack them on top of each other, a more ambitious goal.

Analysts say AMD and others are likely to do some form of graphics and memory stack by 2015. I suspect no one knows yet whether the 2.5- or 3-D techniques will be the best fit come 2015. But both these techniques are getting a lot of attention as the next steps in silicon process technology become increasingly costly and complex due to the delays in extreme ultraviolet lithography.
So at GTC we learned just a little bit of what Nvidia plans to do over the next couple years. The result is we now see how little we know about what anyone will do in the client computing space for the next two or three years. But we can see it is going to be something of a wild ride.
My feeling is that long term, Microsoft will become less and less relevant to anything. Look how they missed the boat on smartphones. Everyone is getting along just fine without them. They seem to be set to miss the boat on ARM servers as well, and I really don't think they will be missed there either.
"And we are still waiting to hear anything about Windows Server for ARM."
ARM servers are of most interest to big cloud data centers. Cloud infrastructure is largely open source and Linux based, and doesn't care about the architecture it runs on.
The success of ARM in the server space has very little to do with Windows Server.
Frankly, I don't now if the CUDA vs. OpenCL was answered at GTC this year. As GPGPU based computing is gaining prominence in CAE/CAD/EDA tools market, developers of simulation tools seemed to be left with a choice that nearly doubles their effort in code development.
Rick, regarding "...Google has been mum on any plans for Android in notebooks..." -there is Android's daddy on notebooks today...Linux! I am skeptical about Google taking on M'soft on OS's for notebooks, in light of Windows8's success(?) so far! If touch-based computing is the determining factor, it may very well be that Windows8 and beyond will prevail on notebooks (assuming that notebooks will exist in the future!).
