Decent, but not good enough compared to Intels. Run some branchy bench you know of and use CodeAnalyst to check the misprediction rates. I'll run the same with Intel Skylake.
Excavator's branch prediction rates seem like they should be better than Sandy Bridge, judging by Agner's comments.
Pages 28 & 33
I disagree that it's just cache and the rest was equally matched to Intel.
Slow cache is also a major oversimplification - it's ways, it's how many accesses per line can be made simultaneously, it's the latency and bandwidth with cache contention.
If Excavator had even Sandy Bridge level caches, things would be a lot different.
Oh, and that's 5Ghz Bulldozer vs 4.5Ghz Sandy Bridge.
