Consumers also care about getting better energy efficiency out of their battery powered devices. It's really just the desktop PC market where being stuck with 14nm CPUs is a non-issue, because wall power is cheap and cooling is easy.
I agree, they care about battery performance, but they don't understand the correlation of CPU to battery so they don't purchase based on that criteria.
The vendor that makes the device definitely cares though I wonder how much Intel cares about consumer oroducts as percentage of mkt share compared to servers.
