Would have been nice to know how much power they were drawing at that frequency, as well as how much they jacked the core voltage

"Overclocking, for those that have a difficult time obeying Moore's Law." ;)

Very nice effort to see/show what can be done. I would like to have seen the setup..I would imagine that they had some serious cooling. I wonder what the DRAM memory speeds were and how much they had to slow down the external memory accesses? If they can get half that speed in a normally cooled machine then I would be very impressed.

BS. Who cares? Another science project...Ship me an air cooled 4GHz processor and I'll be impressed.

Publicity stunt or not, it's pretty impressive to achieve almost 8.5 GHz on a CMOS microprocessor, operating in a real system, even though they used liquid nitrogen cooling to do it. They also got very impressive overclocking numbers with consumer-friendly cooling systems, as you can see in the YouTube video of this event. With phase-change cooling (refrigeration to -40 C), which is a real consumer system option, overclocking to 6 GHz or so is practical. Gamers will be thrilled!

I think this is a publicity stunt on part of AMD...I doubt we will see a commercial part operating at that frequency...if that operation requires 77K temperature then the real value of that record is pretty doubtful...you get more gain by running multicores these days rather then speeding up the clock...Kris

The implication of the AMD press release is that this is a plain vanilla CMOS silicon processor....as it is part of Bulldozer introduction it is probably in 32-nm SOI HKMG and would probably be normally specified at 1 to 1.5-GHz. I understand that "overclockers" do their thing by bathing the processor in liquid nitrogen!!!

That is impressive. Did they use silicon or Ge? Impressive feat. Yet, is speed the key factor now? MPU should look for optimality and not just speed.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
