[B&C.it] AMD Cancels Project Skybridge because GloFo terminated 20nm BULK

Today, as proof of this, another of our colleague informed us that Global Foundries has definitively canceled its 20nm, and this cancellation would be the basis of cancellation of the project Skybridge. Skybridge has not been canceled because no one was interested, but because having to redesign the Amur and Nolan (already well under way with the 20nm GloFo) for 28nm SHP of GlobalFoundries or TSMC 20nm SOC would have been decidedly uneconomical. Simply put, AMD would not recover the money spent in four different designs (two Amur and two for Nolan) SoC selling so cheap.

So, when AMD says that Skybridge was canceled because few companies were attractive to it, generally speaking the truth. But they did not say the whole truth, probably, in our opinion, not to create friction with GloFo (which, it should be remembered, a few years ago wiped out the 28nm SOI on which AMD would have to shrink Steamroller). It should be remembered that in addition GlobalFoundries, Samsung has also canceled its 20nm evolution of the unfortunate LPM (Advanced Process Technologies program). It is, after all, a very unfortunate one node to 20nm.

Project Skybridge was announced about a year ago and was quite a venturous project in which AMD planned to combine x86 and ARM into a common platform. Bitsandchips seems to claim that the reason behind AMD ending this project was because Global Foundries canceled its 20nm process; it appears this is due to the economical impracticability. Project Skybridge was AMD's unifying computing architecture which would allow x86 Cores and ARM cores to become pin-to-pin compatible. Project Skybridge was to focus on a new family of APUs along with SOCs founded on the low-power 20nm Cortex A57 cores with AMD’s GCN core architecture. Project SkyBridge would have allowed these low-power ARM based SOCs to run on the same exact motherboards as the x86 low-power SOCs which were going to feature AMD’s Puma+ cores. Theses ARM SOCs would have also been the first to feature full support for Android OS platform. It's sad that this endeavor isn't going to see the light, but as Bitsandchips says at the end of their article, the philosophy behind it remains. This would have greatly helped AMD in their entrance to the mobile market with Android support, but it looks like AMD is going to have to find a different angle to gain proper entry.

WOW! Sounds like GloFo has some serious issues behind their production.

ARM chips are built into AMD's Kaveri processors (For security), but they are not unified.

AMD could pick it back up if they go with a new fab.

What makes 20nm so hard compared to Intel 22nm ?
post #4 of 7
Was Skybridge going to bring anything to the table that would affect power users or mainstream users?

It'd unify mainstream systems. Windows could unify their OS to run x86 apps as well as ARM.

The real temptation is the server market.

Isn't there ARM emulation of some sort?

Well technically yes, you don't need an ARM chip to assist. You can use Android software to emulate or even use bluestacks. Tons of others too. Best way is to use Virtual Box.
