One has to be careful with benchmarks and where each process and product were designed to operate, but is there any wonder why Intel products have failed in mobile and tablets.
The process technologist claim the recent process are great in density and the FINFET scale great for low voltage and low power, yet on the third attempt to do a low power product the whole line got canceled. Really three generations of trying to do optimized process and design and the product fails to be competitive with inferior process nodes being manufactured by smaller design teams.
Now that ARM and the softbank is funding lots of people and designs on 10nm for servers, I'd say Intel is more than in trouble.
They are trying to compete in commodity business where the outcome is going to be losses
They are trying to compete in high volume low margin where the outcome is going to be losses
The competition is coming for the high margin low volume server business, means dropping margins.
Net will be more structural changes, wholesale cost cutting, and more layoffs offcourse, but just like the response to ARM, it'll be too little to late, LOL
