CPU bug wars update: the latest attack against AMD CPUs just leaks memory access patterns. This is basically inherent in how caches work. It's not even a speculation attack. Intel still has the lead in designing CPUs that give up all their secrets *by design* in speculation.
Yes, see the *in speculation* part. Intel didn't design their CPUs to be insecure under a normal architectural view, the problem is they designed them to be explicitly insecure (probably with "performance"/"cost" arguments) **in speculation** and ignored the possibility of leaks.

You said they designed it "to give up secrets". They did not. That's clearly wrong. They designed it to execute code faster. The fact that it gives up secrets (and we both agree that's the case) is a SIDE-EFFECT of their design, not an effect.

Look, if you're going to keep ignoring the "in speculation" qualifier, I give up. They DESIGNED the CPU to propagate secrets all the way through the microarchitectural pipeline only stopping at retirement.
