7nm now vs 10nm sometime in the future
AMD 7nm based CPUs have already been demonstrated and are expected to be on sale in July this year where as Intel is not expected to have high performance 10nm CPUs on sale before late 2020 at the earliest. By the time that the Intel CPUs arrive they will be in the position where they have to compete on both performance and price - not just on the Intel name vs the AMD name as customers will have gotten used to using AMD CPUs.
With the Ryzen 3 range expected to reach 16 cores/32 threads, the Threadripper 32 cores/64 threads and the EPYC range 64 cores/128 threads, Intel will have its work cut out to try to produce competitive CPUs at a competitive price. (Intel was only able to produce a 56 core package by sticking 2 separate 28 core CPUs inside a single package with a 400W TDP.)
Not a good time to be an Intel stockholder.
