The clock mesh "thingy" is a resonant clock mesh which is a power recycling technology. It's analogous to the KERS system that F1 cars use. The promise is for 4+ GHz. stock clocks at a lower power level than we currently enjoy . It'll also be useful in SoC's that require low power consumption. I hope it doesn't resonate too loudly, the stock fan on my 8150 just about drove me bonkers.
