Is Intel-PT over-engineered and not really needed in practice?

- Sesse__ 1y agoI've used Intel PT several times; it's completely unbeatable for some things. In general, Intel is _way_ ahead of AMD in the performance monitoring game. For instance, IBS is a really poor replacement for PEBS (it still hits the wrong instructions, it just re-weights them and this rarely goes well), which makes profiling anything branchy or memory-bound really hard. This is the only real reason why I prefer to buy Intel CPUs still myself (although I understand this is a niche use case!).
