At the level where large, security-centric organizations make decisions, these instances argue for getting AMD in the door like nothing else that I can recall. So, it's a good time for AMD to have such performant hardware and a process advantage. If it stays this way for a decade, I'll be able to put in a PO for AMD hardware...
The problem is, these leaky cache issues come from 'performant' hardware. It is the pipeline optimization that leads to the side channel.
There are cache architectures (such as pseudo random replacement) that are much more difficult to perform side channel attacks on, but have slightly lower performance.
Intel's problem has been its relentless pursuit of per clock performance, and that has led to some of these side channel attacks. Cache coherency on multi-core is hard.
My guess is that if the market share of Intel and AMD were swapped, you would see similar cache attacks on AMD.
