AMD Piledriver cores will clock over 4GHz, employ 'resonant clock mesh'

AMD's Trinity APU can do some remarkable things, but we still don't know exactly what magic ingredients make its Piledriver cores superior to the tepidly received Bulldozer. Now though, a firm called Cyclos claims it's supplying 'resonant clock mesh' power-saving technology for use in the new module. In speaking to the media, it's revealed that this will help to enable a "4+ GHz" factory clock speed, which sounds high if it definitely refers to an integrated chip with low-power credentials. As for the resonant clock mesh itself, it's a bit like KERS for processors: it recycles clock power instead of letting it dissipate and thereby enables higher clock speeds in "next generation SoCs that also require ultra-low power consumption." We also know that the technology is financially backed by ARM and Siemens and has seen precious little implementation prior to AMD -- which is fine, so long as all that resonance doesn't make our rig hum even louder.
