All Haswell and Broadwell events and offcore masks used in these lists are identical. However Haswell is very different from the Sandy Bridge list that was used previously. That fixes a wide range of mis-counting cache events. The node events are now only for retired memory events, so prefetching and speculative memory accesses are not included. They are PEBS capable now, which makes it much easier to sample for them, plus it's possible to create address maps with -d. The prefetch events are gone now. They way the hardware counts them is very misleading (some prefetches included, others not), so it seemed best to leave them out.
