Intel’s launch of quad-core processors will drive adoption of high-end Xeon servers and virtualization technology, but it may take some time before the platform takes off in the marketplace, solution providers say.
The Santa Clara, Calif.-based chip giant on Tuesday rolled out the industry’s first four-core processors, including three quad-core Xeon 5300 processors and the Core 2 Extreme Quad-Core Processor QX6700.
And in the first quarter of 2007, Intel plans to launch two more quad-cores: a low-voltage version for ultra-dense servers in a thermal envelope of 50 watts, and a single-socket processor for desktops and workstations. The mainstream quad-core desktop processor will be available in January, in time for the retail launch of Microsoft’s Windows Vista operating system, Intel said.
Partners applauded the improved performance of the quad-core and the opportunities it brings to the channel for servers, workstations and desktop PCs. Intel, which launched its first dual-core processors last April, has made a speedy ascent to quad-core, they said.
“It’s very cool that we’re already starting to talk about quad-cores, since dual-cores are just starting to really gain traction and acceptance in the mainstream market,” said Todd Swank, director of marketing at Nor-Tech, a system builder in Burnsville, Minn. “2007 is going to be a big year for computer resellers. With Vista being launched and these new hardware platforms, we’re setting the stage for a whole new wave of innovative applications to be launched.”
The quad-core Xeon 5300 chips have clock speeds ranging from 1.6GHz to 2.66GHz and front-side bus speeds of 1066MHz to 1333MHz in thermal envelopes of 80 watts. A performance-optimized, 120-watt version of the quad-core Xeon is available at a new price point of $1,172.
NEW YORK (Reuters) – Cingular Wireless, the No. 1 U.S. wireless service, said on Monday it would sell a slim cell phone from Samsung Electronics Co. Ltd (005930.KS: Quote, Profile, Research) with a computer-like keyboard and a music and video player aimed at attracting both business and consumer customers.
The BlackJack, the latest device with both entertainment and business features such as e-mail, follows the footsteps of the “Q” phone from Motorola Inc (MOT.N: Quote, Profile, Research) and the Pearl from Research In Motion Ltd (RIM.TO: Quote, Profile, Research), both launched earlier this year.
Cingular, a venture of AT&T Inc (T.N: Quote, Profile, Research) and BellSouth Corp. (BLS.N: Quote, Profile, Research), said the phone, which runs software from Microsoft Corp. (MSFT.O: Quote, Profile, Research), would sell for $199 to customers who sign up for a two-year service plan.
The No. 2 U.S. mobile service, Verizon Wireless, owned by Verizon Communications Inc (VZ.N: Quote, Profile, Research) and Vodafone Group Plc (VOD.L: Quote, Profile, Research), now sells the “Q” for $99 after a rebate.

Cancer vaccine harnesses similarities between embryos and tumours.
Embryonic stem cells, the controversial and versatile cells that seem able to do just about anything, have now expanded their repertoire into cancer prevention. A vaccine made from these cells shields mice against developing lung cancer under conditions thought to mimic the effects of smoking.
Safety concerns about injecting stem cells into humans mean that regulatory agencies are unlikely to approve human tests of the vaccine, says lead researcher John Eaton at the University of Louisville in Kentucky.
Nevertheless, he thinks the vaccine is worth testing in people at high risk of developing cancer, such as heavy smokers or people with certain genetic mutations.
Other researchers are more cautious. Cancer vaccines, particularly vaccines made from cells, are notoriously more effective in mice than people, says Jeffrey Weber, an immunotherapist at the University of Southern California in Los Angeles. “The idea is interesting, but the execution may be impossible,” he says.
But both Weber and Eaton agree that the finding could lead to new ways to prevent or treat cancer.
Build this Skype server to provide 24/7 phone service through regular phone handsets in your home—and save a bundle of money in the process!
One irritating feature of Skype is that it must be running on a computer for you to make and receive calls. That is, when your computer is off, Skype doesn’t work. Moreover, when you run Skype on the computer you use day in and day out, Skype’s performance (call quality, reliability and so forth) can suffer if you are doing other things that deprive it of the runtime resources it needs.
My solution was to build a Skype server that provides 24/7 phone service with the minimum of hassle and fuss. By dumping your regular phone company and taking back control of your home phone wiring using a Skype server, you will have not only a phone system with nearly the same capabilities as before—indeed, in some ways better—you will also save a bundle of money! In my case, I save a little less than $700 US each year (this year, next year, and the year after that, and so on), or about 82% off of my old phone bill.
Using a Skype server plugged in to the existing copper phone wiring of your home means that you can lift a receiver anywhere in your home, at any time, and get a regular dial tone. Incoming calls either from Skype users or regular phones ring all handsets throughout your home. Basically, you can make Skype behave like a regular phone line, but at a tiny fraction of the cost.
You have three choices when building a Skype server: buy a new computer, build a new computer or convert an old machine you have conveniently at hand. This article shows you how to build a new computer from scratch to act as a Skype server. However, whichever path you take, the configuration is the same and is covered in this article.
Skype is not an all-or-nothing proposition, as you can mix and match Skype with your existing phone system, and run the new alongside the old in parallel. That way you have the comfort of having a regular land line and, at the same time, reap the benefits of Skype, such as free Skype-to-Skype calls, and long-distance and international calls at very low rates. This is the approach this article takes, and the configuration you should be aiming for should look something like that in Figure 1. Keeping one of your regular phone lines neatly sidesteps issues such as 911, 411, regular fax and alarm system monitoring (make sure the regular phone line you keep is the one used by your home alarm).
The setup shown in Figure 1 also simplifies the configuration of your Skype server a good deal. Indeed, making multiple instances of Skype run under Linux to support multiple phone lines is another article in itself!
Munich (Germany) – AMD chose to reveal first official details about its 4×4, dual-socket processor platform at a PR event in Munich. 4×4 apparently is still on track for a November release, while AMD’s U.S. representatives aren’t ready yet to talk about the firm’s answer to Intel’s quad-core CPU. AMD confirmed at the event that 4×4 will be introduced with an Nvidia chipset and prices around $1000.
There have been very few processor platforms that have been treated as secretive as AMD’s 4×4. Industry sources told TG Daily that the technology will launch on November 14, but – at least to our knowledge – AMD has not engaged in official briefings for the U.S. press yet. A first, very careful, attempt to prepare journalists about the apparently impending product introduction has taken place today in Munich, where desktop marketing director Leslie Sobon confirmed some rumors and provided some launch details.
SAN JOSE, Calif., Nov. 8 – A $90 million supercomputer made for nuclear weapons simulation cannot yet be rivaled by a single PC chip for a serious video gamer. But the gap is closing quickly�
Indeed, a new breed of consumer-oriented graphics chips have roughly the brute computing processing power of the world’s fastest computing system of just seven years ago. And the latest advance came Wednesday when the Nvidia Corporation introduced its next-generation processor, capable of more than three trillion mathematical operations per second.
Nvidia and its rival, ATI Technologies, which was recently acquired by the microprocessor maker Advanced Micro Devices, are engaged in a technology race that is rapidly changing the face of computing as the chips � known as graphical processing units, or G.P.U.�s � take on more general capabilities.
In recent years, the lead has switched quickly with each new family of chips, and for the moment the new chip, the GeForce 8800, appears to give the performance advantage to Nvidia.
