AMD has smashed the overclocking speed record thanks to the use of liquid nitrogen and liquid helium
AMD has entered the Guinness World Book Of Records book after it smashed the previous overclocking frequency record using an 8-core AMD FX desktop processor.
This chip is AMD’s forthcoming FX processor (codenamed Bulldozer), which will launch in the fourth quarter of this year.
The world record was set by a team of people dubbed Team AMD FX, who are said to be made of up AMD technologists as well as elite overclocking specialists.
World Record
At an event in Texas on 31 August they utilised a AMD FX CPU to set the world record, where they achieved an overclocked frequency of 8.429 GHz on a near-production 8-core AMD FX 8150 (Bulldozer) processor sample.
The previous world record was 8.308GHz.
Although the event took place last month, it took until 13 September for AMD to be officially recognised as achieving the Guinness World Record for the “Highest Frequency of a Computer Processor,” by overclocking the upcoming 8-core AMD FX desktop processor.
“The record-breaking processor speed that resides in the AMD FX CPU clearly demonstrates performance gains for the new AMD ‘Bulldozer’ multi-core architecture, which will provide x86 computing power for this CPU and future AMD Accelerated Processing Units,” said Chris Cloran, corporate vice president and general manager, at AMD.
“Along with world-record frequencies, the AMD FX processor will enable an unrivalled enthusiast PC experience for the money – extreme multi-display gaming, mega-tasking and HD content creation,” he added.
“We applaud AMD for their entry into Guinness World Records for achieving the Highest Frequency of a Computer Processor,” said Freddie Hoff, adjudicator for Guinness World Records. “We congratulate everyone involved in this record-breaking achievement.”
Combating Heat
Overclocking is the process of running a processor at a higher clock rate than it was designed for by its maker. It significantly increases the speed of the processor, but it does have drawbacks.
The main drawbacks are power and heat.
Essentially overclocking records like this are something of a balancing act, as the researchers have to apply power (i.e. voltage) to the chip to improve clock speed (i.e. performance), whilst at the same time combating the massive build up of heat.
Most desktop and laptop PCs for example use fans to shunt this heat out of the computer casing. Some servers and mainframes use liquid cooling, in the form of water or oil.
For the record attempt however, Team AMD FX used a combination of liquid nitrogen and liquid helium to combat the heat. Indeed the experiment showed that the AMD FX CPU is robust enough to handle increased voltage, but that it is also extremely resilience to cold, and has excellent frequency scaling with lower operating temperatures.
