AMD "Advanced Micro Devices has hired JPMorgan Chase & Co to explore options, which could include a potential sale, as the chipmaker struggles to find a role in an industry increasingly focused on mobile and away from traditional PCs, according to three sources familiar with the situation." Woah. Bad news for competition in the x86 space.

Arm64 is a nice odd ball. It requires less silicon than its Arm 32 bit relations. Uses less power per core than its 32 bit relations and is faster. Yet it also has backwards compatibility support.

Arm pulled of some nice creative design voodoo with the Arm64 bit design.


If that's the case, I wonder how viable it would be to sell nothing but ARM64 cores but have some branded as 32 bit until the user pays for the upgrade.

I wouldn't be surprised if the ARM64 is not cheaper to produce than ARM 32-bit.

Part of the improvements probably came from using going with a smaller process, for example from 32nm to 22nm.

I just wonder if a company focused on nothing but the ARM64, would their fabrication or production process be heavily simplified by being able to focus their lines on just one design rather than multiple designs, especially if the ARM64 is going to be indistinguishable from ARM32 when running in 32 bit.
