Re: For now, it doesn't matter yet
Here’s the problem for Intel:
They don’t even come top of the table for SPEC performance. (that honour goes to a Fujitsu SPARC machine tested back in 2017, see https://www.spec.org/cpu2017/results/res2017q4/cpu2017-20171211-01435.html )
AMD are currently making CPUs that in 2 socket configuration need an 8 socket Xeon machine to beat them (see https://www.spec.org/cpu2017/results/res2020q2/cpu2017-20200525-22554.html ).
The Intel boxes are vastly more expensive to buy and to run (all those sockets need lots of power).
There is a limited market for “absolutely the fastest machine you can buy”, mostly companies want the best performance they can afford within their budget, or target a given performance level and then see how cheap they can buy it. Intel have a certain amount of inertia that they can rely on here, as it takes companies a while to test and qualify new hardware, but they are starting to come under fire as the AMD alternatives are looking increasingly attractive. They need to be cheaper and consume less power to compete, but to do so needs a smaller, more advanced process than 14nm, which they haven’t really got (even 10nm isn’t ready for server grade chips yet).
