I've been noticing that some Bay Trail CPUs are used in laptops. These CPUs have have great specs from the outside. Example Pentium N3530 is quad core and has a max clock of 2.56 GHz. However, I've seen some benchmarks that show that Haswell U CPUs (such as the Pentium 3558U only 2 cores and 1.8 GHz) actually beat out the Bay Trail.
I have two questions. My first one is why? Why do benchmarks show that Pentium N class Bay Trail get thrashed by Haswell even though they have seemingly better specs?
My second one is, how can Bay Trail CPUs sustain higher clock rates and sport up to 4 cores, and yet still have a smaller TDP? For example, the Pentium N3530 has a TDP of only 7.5 watts and the Pentium 3558 has a TDP of 15 watts even though it has a much lower clock rate and two fewer cores.
