The benchmarks that you have in mind had probably been run on some later Piledriver/Steamroller/Excavator models, which corrected some of the initial problems, like the too low instruction decoding throughput, and which raised the clock frequency, due to an improved CMOS SOS process.
I also had an AMD Richland APU of 4.4 GHz, which was reasonably faster for most tasks than an Intel Haswell U i5, but the speed ratio was much, much less than the power consumption ratio of 100 W for AMD vs. 15 W for Intel.
The original Bulldozer fared much worse against Sandy Bridge.
Hmm, but AFAIK the performance didn't radically improve in P/S/E - and anyway, I had assumed that this whole discussion also covered them because B/P/S/E are still all using the same architecture - for instance : doesn't TFA apply to P/S/E ?
