Yep- this little wedge is just one battle. The war is much bigger and it seems to me that the war will tilt this battle in the favor of ARM. Battles are always difficult to predict, but I'd put my money on the one winning the arms race...
What are you talking about? ARM has the little wedge on the chart in the article about a design yet to tape out on a vendor (TMSC) that has not demostrated any working logic designs on a 14nm process. You have to put your boots on first before you can win a war.
One more indication that ARM has won the architecture war. And it isn't even about the hardware.
ARM is a ho-hum hardware architecture, but it turns out that isn't really important. It's just good enough so that alternatives with an additional 15% or so efficiency just aren't worth the effort of building an entire architecture infrastructure. Process improvements and software inertia are just too big to fight.
