There might be some upside in workstation/server but those markets are smaller and have more inertia to new chips.
Considering that AMD has 0.2% server market share (saw that number recently in press around Zen release) it has nowhere to go but up.
The first Ryzen parts are pretty impressive, especially getting 8 decent IPC cores clocked at reasonable speeds at reasonable TDP. Not Intel killers some here hoped but staggeringly better than anything AMD had before.
AMD will still lean heavily on price to sell but at least they will be able to sell a fair amount if they can make and bin them in volume.
The best part is finally we have some fire under Intel's ass to release more competitive SKUs of existing products and stop pushing out intros of new products. More better products, less diversity hiring self back patting press releases - finally get it BK? The fate of my remaining INTC holdings awaits your answer.
