This will probably satisfy big clients and partners. Long term it will depend on whether AMD can keep up the pressure. Good times for CPU buyers.
Now that it's 2019 and they're finally claiming to enter high-volume production of 10nm, I have a really hard time taking any claims they make about future lithography nodes at face value.
Obviously, we need to know the definition of "high volume production"...
But as others point out, these are their server parts and not desktop parts yet. We’ll have to see when those start shipping.
I know people like to meme that Intel is never going to advance nodes ever again, but they are finally launching 10nm products. Ice Lake-U is launched and server comes next.
Desktop is going to hold back for a while simply because Coffee Lake/Comet Lake are such high clockers that Ice Lake won't be able to outperform them, and it relieves the strain on 10nm fabs.
Core for core Coffee Lake still outperforms Zen2 through raw clocks, although IPC is starting to fall behind.
