AMD Piledriver Cores to Use Energy Recovery Tech

By - Source: Cyclos | B 46 comments

AMD confirmed that its next-generation Opteron processors and desktop APUs with the Piledriver core will include Cyclos Semiconductor's resonant clock mesh technology.

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.

    Looks promising. but we want to see to believe.

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

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

    optimizing power consumption goes hand in hand with performance, If you use so much power that heat goes through the roof to get that performance, then it's not practical. Lower power consumption (lower heat) means higher clocks and more room to improve performance.

    But will it best a 2500k?

    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.

    Lets run some tests, shall we!

    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.

    I like what you did there ;)

    Will it run crysis?

    I don't care what you do AMD, just get to being on par in performance with Sandy Bridge at this point. Ivy is just a die shrink so no need to worry, you should probably also worry about Haswell.

    This is one of the most notable changes to come out for Piledriver (publicly) in a while.

    Now if they can fix the cache latencies.

    Their mobile APUs are actually already fairly power efficient. I hope this trend continues and extends a bit into desktop mid-range territory.

    actually they are aimed at mid-segments

    Fine, I'll smash your fancy i5 2500k with my dual Netburst Xeon 5080 bathed in liquid helium and clocked at 8 GHz. What now?

    I'm sure your power bill would hate you and it's not healthy to compete against one self (intel vs intel) :lol:

    I never would have thought of that idea, recapturing power like that.

    But if those processors have coil whine count me out.
