AMD's Piledriver To Hit 4GHz+ With Resonant Clock Mesh

MojoKid writes about some interesting news from AMD. From the article: "Advanced Micro Devices plans to use resonant clock mesh (PDF) technology developed by Cyclos Semiconductor to push its Piledriver processor architecture to 4GHz and beyond, the company announced at the International Solid State Circuits Conferences (ISSCC) in San Francisco. Cyclos is the only supplier of resonant clock mesh IP, which AMD has licensed and implemented into its x86 Piledriver core for Opteron server processors and Accelerated Processing Units. Resonant clock mesh technology will not only lead to higher clocked processors, but also significant power savings. According to Cyclos, the new technology is capable of reducing power consumption by 10 percent or bumping up clockspeeds by 10 percent without altering the TDP." Unfortunately, aside from a fuzzy whitepaper, actual technical details are all behind IEEE and other paywalls with useless abstracts.

Resonant Clock Mesh?

Sounds fake. Like Hyperthreading. Sounds like they are doing some trick to make the numbers better, but not really improve any performance.

But I'm just an armchair slashfag know-it-all.

There are no technical details.

Cyclos is the only supplier of resonant clock mesh IP.

There are no technical details. It's intellectual property, so it's powered by pixie dust, mana potions, and lawyers. Can't get more meaningful than that.

99.99% of users don't work in parallel programming.

But the 0.01% who do, each write 10,000 programs at a time
