AMD should ask Intel to fab their chips

I've seen that these future AMD parts will be 28nm only in mid 2014, when Intel will deliver the next BayTrail iteration in 14nm; from an economic point of view it's a huge gap when you can bake 4 times more chips on the same wafer, notwithstanding the higher yields Intel is credited; It's time for AMD to ask Intel to fab their x86 parts, and i think it's in Intel's best interest too.

Oh, got it. Thanks for the clarification, Rick. On re-reading, it was already stated clearly.

Rick-

Thanx for the details. What is the main thing the standard get used for? Does it implement encryption/decryption, authorization, etc?

Thanx!

@DrFPGA: TrustZone alrready is an implementation of a hw-backed security standard set by the ad hoc Trusted Computing Group about a decade ago or more.

Intel and AMD and others have their own implmentations as do others with subset standards for differet apps like HDDs and etc. ARM just has a nice name for its version.

Is trust zone going to be the new standard? If so what does this mean for the industry? Good or bad? Anyone know more details?

@Bert: To be clear ythe Cortex A5 is only to handle TrustZone security. It is not to Run Windows RT, Android r any other ARM-based apps.

Right, but unless I'm missing something, this is great news for AMD, isn't it? The Microsoft Surface RT uses an Nvidia ARM core of some sort, but it can only run Windows RT. Instead the Surface Pro uses an Intel Core i5 and runs a proper PC-type of Windows, a PC type of Office, and other PC apps.

So here we have AMD offering a full-fledged x86 ARM processor, capable of Running Windows 8.1 and presumably any other PC apps. Cool, no? It should promise longer battery life than what's possible with the Core i5, but without the penalty you pay with the Surface RT.

Sounds to me like the new definition of "PC" is coming on fast. And AMD has a meaningful offering in this camp.

I have see Intel Clover and Bay Trail Atom-based SoCs running Android for production tablets. AMD, not yet.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
