AMD Piledriver Cores to Use Energy Recovery Tech

In a speech at ISSCC 2012, AMD and Cyclos provided first details about the IP that will be embedded in the Piledriver core to assist in achieving a clock speed that exceeds 4 GHz.

According to Cyclos, its resonant clock mesh (RCM) technology is similar to the technique some hybrid cars use via KERS, short for kinetic energy recovery system. Inductive-capacitive oscillators are leveraged in mesh-based high-performance clock distribution networks to deliver "high-precision timing while dissipating almost no power." In effect, RCM promises to recycle clock power to enable lower power consumption or higher clock speeds. AMD said that the technology result isa 24 percent drop in clock distribution power. The total IC power reduction is, depending on the chip design, estimated between 5 and 30 percent, but will be at the lower end (5 to 10 percent) in Piledriver.

AMD's Piledriver is the first high-volume processor core to use the RCM IP.

    But will it best a 2500k?

  • Now if only AMD could get Drag Reduction System (DRS) going and up their instructions-per-cycle we could have a great race!

    amd is making bold claims about power efficiency again.
    hopefully they'll do it right this time and not blame on everything else like they did with bulldozer.

    Looks promising. but we want to see to believe.

    Bulldozer can have eight cores.

    Will the HD4K best the iGPU inside Trinity?

    Trade offs mate, trade offs. Trinity is not aimed to the mid/high segments... At least, they should not be :P

    Cheers!

    I'm not sure they need trade offs. Bulldozer is fine as it is for the most of us. They just need to lower TDP and stuck it in Trinity.

    First beat Intel in performance, then you can get to do power optimization :]
