1. Comment - 500 GHz IBM Chip Breaks Speed Record

   I have one of those 10,000 RPM Raptors-generally makes a difference. I bought mine about two years ago. I have read, but not confirmed, that the new Barracuda approaches the Raptor performance.

   Spend a little bit of time reading about Vista and you will see that Microsoft has a hardware certification planned in the works that includes a hybrid hard drive/nonvolatile RAM hard drive specification that will permit superfast boot up's and shutdowns. Sheesh, some people who post about technology seem to believe that nothing is ever going to change. It's so weird.

   They were clearly talking about a " chip ":
   
   "For the first time, Georgia Tech and IBM have demonstrated that speeds of half a trillion cycles per second can be achieved in a commercial silicon-based technology, using large wafers and silicon-compatible low-cost manufacturing techniques," said John D. Cressler, Byers Professor in Georgia Tech's School of Electrical and Computer Engineering, and a researcher in the Georgia Electronic Design Center (GEDC) at Georgia Tech. "This work redefines the upper bounds of what is possible using silicon-germanium nanotechnology techniques."

   The accomplishment will be reported in the July issue of the journal IEEE Electron Device Letters. The research has been supported by IBM, NASA, and the GEDC at Georgia Tech.
   
   "This groundbreaking collaborative research by Georgia Tech and IBM redefines the performance limits of silicon-based semiconductors," said Bernie Meyerson, vice president and chief technologist at the IBM Systems and Technology Group. "IBM is committed to working closely with our academic and industry partners to deliver the insight and innovation that will enable a new generation of high-performance, energy efficient microprocessors."
   
   The silicon-germanium heterojunction bipolar transistors built by the IBM-Georgia Tech team operated at frequencies above 500 GHz at 4.5 Kelvins – a temperature attained using liquid helium cooling. At room temperature, these devices operated at approximately 350 Ghz. Performance measurements were made using a specialized high-frequency test system in the Georgia Electronic Design Center.
   
   The devices used in the research are from a prototype fourth-generation SiGe technology fabricated at IBM on a 200-millimeter wafer using an older un-optimized mask set. Simulations suggest that the technology could ultimately support much higher (near-Terahertz) operational frequencies at room temperature, Cressler said.

   "Having a silicon-based technology that is compatible with low-cost IC manufacturing – while still providing these extreme levels of performance – allows us to envision integrating these devices into systems that would be affordable for emerging commercial markets as well as defense applications," Cressler said.
   
   The next step in this research will be to understand the physics behind the silicon-germanium devices, which display some unusual properties at these extremely low temperatures.
   
   "We observe effects in these devices at cryogenic temperatures which potentially make them faster than simple theory would suggest, and may allow us to ultimately make the devices even faster," said Cressler, who heads the world's largest university-based silicon-germanium research team at Georgia Tech. "Understanding the basic physics of these advanced transistors arms us with knowledge that could make the next generation of silicon-based integrated circuits even better."

   Have you actually ever used MS Vista? I thought not. I installed it (beta) on the same machine that formerly ran Windows XP. It is at least as quick and responsive as as XP.
