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.
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!!!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
