Ask HN: Why are Intel processors more vulnerable than AMD?

Is AMD better at security than Intel?([1]), ([2]). Why are there less security vulnerabilities in AMD?

Intel checks permissions after performing a memory access (which allows the side effects of that access to be visible) but AMD checks before.

Also AMD doesn't have SGX so they can't have SGX vulnerabilities.

One possibility is that AMD sales were really low until they came out with Threadripper. Security researchers just didn't put the time into a CPU that's not very common.

There are similar AMD vulnerabilities coming out now:
