Magnetic Materials Could Make Computers 1,000 Times More Powerful

If you have ever had to actually use your laptop on your lap, you know all too well that they can produce a ton of heat, especially when the processor is working hard. No matter how advanced computer technology gets, the amount of heat that a computer produces is something we can't seem to get away from. If you think about it, all of the extra heat given off is just wasted energy that could be used for something else. A team of engineers at UCLA have found a way to make integrated circuits more efficient using a class of magnetic materials that are called multiferroics.

Basically, everything you use daily, like your computer, phone, TV, and many other things, relies on tons of transistors packed together making an integrated circuit. When chained together, transistors act as logic gates. The energy passing through these transistors results in large amounts of heat and loss of electrons. There really shouldn't be a way around it, but multiferroic materials have found a way to bypass this.

By simply applying an alternate voltage, a multiferroic material can be switched on or off. Doing this allows it to carry power to different parts through spinning electrons instead of actually moving them. This effect is call a "spin wave bus". The energy of the wave moves in, but the actual molecules don't have to move at all. It is a little bit hard to understand, but trust me... that's how it works.

There was actually an experiment that the team did to test the ability of the materials to keep a stable spin wave bus. The device that they used in this experiment was made of nickel-based film on a piezoelectric substrate. The initial voltage is applied here to generate the spin wave. In the middle of the chip they used for the experiment was a 5-micrometer-wide ferromagnetic strip, which is where everything happens. The strip is the waveguide for the spin wave bus and directs power from one section to another without moving any electrons at all.

The experiment worked and successfully generated a voltage-driven spin wave. It is still a super long way away from replacing a regular charge current, but the team thinks that the improved efficiency of this method could make processors 1,000 times more efficient at very least. This would mean that there could be a whole new generation of computers that could work so much harder with a lot less power. The possibilities are endless.

Upgraded Samsung Series 7 Gamer Laptop Set to Hit U.S. in April

Us laptop gamers here in the states have been pretty envious of our European brothers as they have had the privilege of buying the Samsung Series 7 Gamer notebook since last spring. Well, this spring (April, to be specific) that envy dies and becomes reborn as jubilation as Samsung will be shipping the Series 7 Gamer to us Yanks while giving it a nice increase in specs at the same time.

The 17" gaming laptop will still have the same aesthetics, as well as the same external features, as its European counterpart, including the 2.1 speaker setup with down-firing Subwoofer, super-bright screen and that big knob thingy that switches the device between power modes, like the Gaming Mode, which clocks up the CPU turbo mode, changes the keyboard backlighting, disables the Windows key and a few other things. The only real external difference is the lack of a 3D display option and the addition of a DisplayPort output.

Crack this bad boy open and you will be able to find the differences. On the inside the Series 7 Gamer gets a nice new set of parts. The second generation Intel Sandy Bridge Core i7 processor is gone, replaced by a quad-core third-generation Intel Ivy Bridge Core i7 processor instead. In addition to that, the graphics have received an increase from the Radeon HD 6970M to the upcoming GeForce GTX 670M. You will still have a Blu-ray drive as well as the 2TB hard drive so nothing's new there.

You will be able to grab this mobile gaming giant when it is released in April for a reasonable $1,799, or whenever Intel's high-end Ivy Bridge chips and Nvidia's next-generation GPUs are ready to go, which we hope is by April because, honestly, we can't hold out on this laptop forever.

Intel Launches Core i3/i5/i7 Chips for Ultra-Portable Laptops

Despite promises of a laptop with an all-day battery life coupled with an inexpensive price, Intel's ultra-low voltage processors, otherwise known as CULVs (Consumer Ultra Low Voltage), haven't exactly been living up to the hype. Part of the reason is that Intel hasn't updated their mobile line of processors with its new Core technology, instead their CULV line has simply been based on Core 2 Duo technology. That is until now.

The chipmaking giant Intel has released their new ulta-low voltage versions of its 32-nm “Nehalem” Core i3, Core i5, and Core i7 processors. This means that Intel’s premiere mainstream processors have been slightly downsized so they can now be installed inside power-sensitive ultra-portable notebook computers. These new chips not only pack a significant performance punch, which Intel says is about 30% faster than their previous ultra-low-voltage offerings, but also use 15 percent less power in the process. The new chips will be identified from their larger counterparts by their part numbers which will end with the letters "um" (i.e. Intel Core i5-430um or Intel Core i7-640um).

“Consumers crave laptops that offer style and performance, and the new 2010 Intel Core Ultra-Low Voltage processors for ultra-thin laptops delivers both, in one sleek design,” said Intel PC Client Group VP and general manager Mooly Eden, in a statement. “Not only are laptops becoming ultra-portable, but with the new processors inside, users will see faster response times and less waiting.”

Like their bigger brethren, ULV versions of the Intel Core chips will feature Turbo Boost and Hyper-Threading technologies enabling the processors to dynamically overclock themselves and devote resources to a single processor core. In addition, the new processors will have a thermal envelope of 17W, which is at least twice as energy efficient as their standard volt Core processors. However, Intel will not be converting its ultra-thin processor offerings completely over to the Core line. ULV versions of the Celeron and Pentium processors will continue to be available to manufacturers and will still be a mainstay among many laptops in the future.

It seems the direction that Intel wants to take its new chips is towards a strange middle ground between very affordable and highly portable, yet slower-performing netbooks and even full-size traditional laptops. The MacBook Air is an example of an ultra-thin laptop that offers powerful portability but is simply too expensive for the average consumer. On the other hand, there is the Toshiba T135 series of ultra-portable laptops which seem to attract far more interest than the Macbook Air for its more reasonable price tag despite being less powerful.

Then there are ultra-thin laptops which tout enhanced performance, such as dual-core Atoms, which offer negligible performance improvements for their cost. It appears that consumers are more interested in average and smaller sized laptops which deliver on affordability. Intel promises that systems will start appearing in June equipped with their new ULV processors, so we'll see soon enough just how they stack up. Already Intel says more than 40 designs based on the chips have been confirmed and are already in the works from makers such as Acer, Lenovo, Asus, and MSI.

Make Your Computer Last Longer

The average computer lasts anywhere from two-five years. Eventually, your computer will tear up beyond repair or become so out-of-date that you can no longer use the latest software or accessories along with it, and you'll have to begin the dreaded, inevitable search for a replacement. Buying a new computer is a hassle if you don't know exactly what you're looking for and you aren't familiar with what's current. And of course, with today's economy and job market, you're probably cutting corners whenever possible. New computers can be expensive. Here are a few tips on how you can make your current computer last longer.

If your computer is older and it's running well, there's no need to get rid of it just yet. If you're using it for simple tasks such as word processing, surfing the internet, or manging pictures, age shouldn't be much of a factor. Routine maintenance will keep your computer running smoothly, save you money, and maybe even extend the life of your PC.

The temperature can have a big impact on your computer and cause a lot of damage. Computers generate a lot of heat and at one time had to be stored in climate-controlled rooms. You don't need to keep your living room or home office at a set temperature, but you do want to keep your PC from overheating. Make sure it's not left in direct sun too long and make sure it's properly ventilated.

You'll also want to keep your computer clean. Extra dust on or around your PC can trap heat and making your cooling fan work even harder. This can lead to lots of wear and tear, and eventually to your fan giving out all together. Be careful where you place the computer. Putting the machine on the floor can lead to lots of dirt and dust build-up. Also avoid any rooms with heavy dust build-up. Of course, no matter how careful you are, your computer is going to accumulate some dust, so you might want to blow it out with compressed air every so often.

Laptops are becoming extremely popular and generally don't last as long as desktops. You may leave your laptop plugged in all the time, but leaving it plugged in is bad for your battery. Apple even recommends users don't keep their laptops constantly plugged in and use the battery at times. A typical battery lasts 300-500 charge cycles, but if you find your battery struggling to stay charged, replacing it is a good idea and an inexpensive way to prevent yourself from having to buy a whole new computer.

Restarting your computer is another way to keep things flowing. Most people reboot when they hit trouble, hoping for a fresh start when the computer comes back on and this is actually a good idea. However, many people also leave their computer running 24/7. There's no set time as to how often you should reboot, but rebooting can give your computer a fresh start, speed things up, and serves as a small refresher to your PC.

Desktops Gone in Three Years?

Everyone (except maybe my parents) know that desktops are becoming less popular. People are trading in their old computers for newer, more portable models or other devices that allow them to perform many of the same functions (browse the web, check email) on the go. But while speaking at the Digital Landscapes Conference, Google Vice President of Global Ad Operations, John Herlihy, made the shocking prediction that desktops would become obsolete in as little as three years. And he says laptops aren't far behind:

"In three years time, desktops will be irrelevant. In Japan, most research is done today on smart phones, not PCs. Mobile makes the world’s information universally accessible. Because there’s more information and because it will be hard to sift through it all, that’s why search will become more and more important. This will create new opportunities for new entrepreneurs to create new business models - ubiquity first, revenue later."

But not everyone sees it that way. People from other major tech companies say that while it's true that smartphones and other similar gadgets are becoming increasingly popular, that doesn't necessarily mean desktops, and especially laptops, are going anywhere. Experts believe people will continue to brace new mobile technology, as well as keeping their home computers for other tasks, allowing the two to compliment each other.

Have you ever tried to type on a mobile phone? No matter how fancy your keyboard is, after a while, your hand's going to cramp up and increasing the size of the mobile phone is impractical. In that case, you may as well be carrying around your laptop. Tasks such as creating large word processing documents on your cell phone is probably not going to become trendy anytime in the near future which would make things so much harder on students and working professionals. The same could be said for screen size and weight. Increasing those things would defeat the purpose of having a mobile phone.

Comfort's not the only reason. First of all, battery life is a major factor. Right now, increasing battery life would mean the same thing as increasing the comfort - more power would mean larger phones. And never mind other factors such as software design. Could you imagine gaming only on your phone?

Personally, I'm not an expert, but I think laptops sales will continue to soar. I also think desktops will be around for longer than three years. They may continue to decrease and in the long run, become obsolete, but I just can't picture anyone giving up their computers in favor of mobile phones.

Will Desktops Ever Make a Comeback?

Laptops are becoming increasingly popular. Personally, I haven't owned a desktop in five years and don't see myself ever going back to being desktop-only household. Nothing beats using my wireless laptop from anywhere in my home. If I'm cooking from a recipe I found online, I just put the computer on my kitchen counter. If I'm sick, tired or just being lazy, I can take the laptop to bed with me. And on nice spring days, I can work outside, on my porch, vs. being tied to my desk and stuck inside all day. Not to mention I can take my computer with me anywhere I go, whether it be a vacation or to a coffee shop with free Wi-Fi.

But it seems as though I'm not alone. Desktop sales are falling and laptop sales on the rise. Does that mean desktops are gone forever? Not according to a few people at AMD and Via.

Patrick Moorehead, a vice president at AMD, told the New York Times he sees the computers reemerging as "small form-factor desktop[s]." Via Vice President Richard Brown is also optimistic, asserting that desktops in the corporate world are not going away anytime soon.

But according to research firm IDC, desktop shipments will decline over the next few years. In the United States, in 2009 alone, desktop shipments were expected to drop 14.2%. In 2010, they will fall another 3.6% and 1.9% in 2011. However, international desktop shipment numbers look a little different. While shipments were expected to decline 12.9% in 2009, they are expected to gradually rise again in the following years: 0.1% in 2010, 1.6% in 2011, 2.0% in 2012 and 0.9% in 2013.

According to Brown, that worldwide increase can be attributed to Asia, "In China and elsewhere, those people have started to desire a real computer when they get home. They want a bigger screen and more power. The desktop offers that."

Even so, laptops and other portable computer shipments are expected to increase at unbelievable, double-digit rates over the next four years, due to the fact that users are becoming increasingly mobile. There's no question notebook computers will continue to dominate the market in the near future but as for the desktop, only time will tell what becomes of it.

New Trends: Computers Give Up CD Drives for Touch-Screens

A recent Associated Press report points out that personal computers are changing rapidly. It has definitely been a year of "out with the old and in with the new" as far as computers go. Laptops and Desktops are missing familiar components, slimming down and gaining lots of cool, new, unique features. Despite the popularity of gadgets such as the iPhone, PCs are still at the heart of the digital world and will likely stay that way for a while to come...even if they look and act a little differently.

One noticable change in the world of new computers is the lack of drives. Optical drives that play CDs and DVDs have been an important part of computers for over a decade. Whether you're watching a movie, listening to music, or installing software, the drives have been part of almost everyone's daily computer usage. Apple started getting rid of drives about two years ago when it first introduced the MacBook Air. Even though that wasn't a mainstream computer, due to its $1,800 pricetag, it was the start of what looks to be a popular trend. Netbooks, which are used mostly for web-browsing, start at $250 and are growing in popularity.

People are using their little laptops to download software, music and movies, while enjoying the convenience and price. The availability of Wi-Fi and cellular internet service combined with services that let you store files online are making the need for drives almost obsolete. Of course, there are the die-hard DVD watchers and CD burners who are not yet ready to give up those drives, but the lack of drives in many computers, particularly laptops does often lead to a lighter price and a much lighter load.

These days, people are also tending to purchase less powerful computers and this is another reason netbooks are becoming more popular. Everyone's been inside a retail establishment and listened to a salesperson rattle off a list of processors, graphics cards, gigabytes of memory and sizes of hard drives, but unless you're a hard-core gmer or a professional video editor, all of that stuff isn't really necessary. People are looking for computers that let them browse the web, email and use word processing applications more than anything right now.

Computer manufacturers aren't just competing with each other these days, they're also having to stand up to smartphone manufacturers, as well. People want to be connected 24/7 it seems and it's easier for that to be possible via a cell phone. "Smarbooks" are being created - think a smartphone-like device that is closer to the size of your laptop than your cell phone, and computer companies are starting to focus on laptop appearanes. Colors, patterns, themes, designs, shapes, and materials are all considered to be an important part of computer manufacturing lately, allowing users to treat their computers more like fashion accessories than tools. People also want thin and light computers that are easier to carry.

And finally, touch-screens are becoming a popular computer trend. Ever since the iPhone was developed in 2007, multi-touch has become more prominent in today's technology. The recently released Windows 7 includes support for a number of multi-touch applications and companies such as Dell and HP are designing software that allow you to browse everything from the web to your music library with your fingers instead of a mouse. And while experts say the touch-screen won't replace the mouse and keyboard, it will most likely become just as important.
