Intel has 2 read and 1 write ports to cache, same as all other high end CPU's, but Intel has three AGU units and thus can use all of those ports. For problems that fit in cache and need lots of bandwidth Intel will win. For much software this would just mean you become RAM bandwidth limited with fewer cores.
Some games and other software where a primary thread is the performance limit would be an easy win for Intel. But for games AMD has better graghics to offset that to a degree.
There are lots of other factors, many of which Intel will have a slight advantage in, AMD Zen was always going to be a small cut below Intel in performance.
It looks like Zen will compete in the budget server market against ARM, and in the mid range laptop/desktop market. A big improvement from the budget laptop/desktop market sliver AMD has now. AMD might be back to struggling break even instead of going out of business. Back to a joke $7 stock. Sound reasonable?
