64-bit computing – coming to a computer near you

Wednesday, February 18th, 2009

The technology enthusiasts who think and feel ideas take time to germinate can now be sure as the 64-bit computing has finally arrived where the software and the operating system run on the 64-bit CPU from AMD or Intel. The operating system of Apple has been 64-bit for nearly five years and Linux for around eight years. However, the compatibility problem has dogged this 64-bit Windows version since Windows XP were introduced. There are a number of key benefits like an improved performance and support for several gigabytes of RAM. However, the question remains why 64-bit now and also why you should care for it now?

To be honest, the promises of 64-bit computing were around for quite a while and some even think it can be a broken promise. However Microsoft offers a 64-bit version for their both Windows XP pro and Windows Vista Ultimate while there are also 64-bit versions freely available for Linux. According to Gartner one PC from every four that is sold today is built with 64-bit operating system. When it comes to hardware, both AMD and Intel have also offered 64-bit processors for several years. Apart form this; the additional RAM that is supported by the several buses is now surprisingly affordable due to the smooth manufacturing process and the typical levels of demand. The most important thing is that several companies like Autodesk, Apple and Adobe also offer their flagship software products in versions of 64-bit. For the first time Adobe offers their Creative Suit 4 with 64-bit version.

Therefore the main benefit has much to do with the memory addressing. Long ago, the master minds working at Intel and several other companies had decided that a PC will require just 32-bit register size as the amount of RAM that a CPU can easily access. Right after that in 2003 AMD had launched the first 64-bit processor called as the Opteron. However the rules suddenly changes as the CPU was able to access a surprising amount of RAM which can be translated to several gigabytes of RAM. This does not mean that you could not install so much of memory but even if you wanted to you could not. Therefore since then the software and operating system have been gradually catching up to the hardware to finally reach then today.

There are basically two main advantages of 64-bit for computers. For the consumers it would be like adding 8GB or 16GB of RAM so that the memory intensive applications like Adobe Photoshop CS4 can have enough overhead to cut off page swapping virtual memory. However running 64-bit version of Adobe Lightroom 2 on MacBook, additional RAM would mean never overloading your computer as it often tries to process several megabytes of images. Additionally for the consumers running 64-bit computing would mean that they never have to worry about how many programs and applications they are running. You will hardly experience a BSOD on a computer with 16GB of RAM as the programs are free to consumer the sufficient RAM they need so that the computer is processing information rapidly.

Lenovo ThinkPad X301 Review

Thursday, January 22nd, 2009

If you are familiar with the ThinkPad X300 of last year then there are very few surprises with the new X301 as it is just a Centrino 2 update. The new Lenovo ThinkPad X301 features the same carbon and glass fiber but is would survive a sales drop with its solid state disk. However like all the ThinkPads the system features a dual pointing system which includes joystick and trackpad with right and left mouse buttons for both side and also a middle mouse bottom. However the trackpad of Lenovo is not very satisfying regardless of how high you set its sensitivity.

The keyboard of this system is an effort of evolution which makes it one of the best keyboards to be used on laptops. Through the heritage of IBM, Lenovo has advanced it down to something which offers both a fast speed typing pad with pleasing travel pack. However users might find one annoyance with the F1 key which is moved towards the left in place of Esc key which is above the F1 key, but the keyboard shortcuts users might probably scowl as they constantly hit the F3 rather than F2. Beign a business laptop the shortcut buttons are sparse that include volume down and up, mute button and ThinkVantage buttons. The webcam and the fingerprint reader are fairly standard features but a feather that X301 has over Apple’s MacBook and R600 of Toshiba is its stereo speakers and also includes a great resolution.

The Lenovo ThinkPad X301 is a business based vista OS laptop that includes an Intel Core 2 duo processor that is clocked at 1.4GHz, 64GB, 2GB of RAM, which is although just Intel Integrated graphics that is only from a few things that MacBook has over this laptop. However the ThinkPad X301 is an upgrade to 64-bit vista if you need to upgrade to 4GB of RAM. The DVD+-RW drive is very pleasing which can be turned off to save battery life or even replaced with a secondary battery if needed. The laptop also features gigabit Ethernet connection with 5300AGB wireless adapter of Intel. The screen quality is acceptable but not great although it has a higher resolution than most of the 13.3 inch laptop screens. There are three USB ports designed in X301 one on the rear and two on the left but the lacking of eSATA can be a problem for several users.

You can also turn off the network location manager of Lenovo that pops up annoyingly when you make a new network connection. However the included notification software can also be annoying and the update manager of Lenovo might frequently error out or the servers might fall offline. However the best thing about Lenovo ThinkPad X301 is that it is light and easily portable which features a higher resolution screen. Although the Lenovo ThinkPad X301 is an improved notebook in an old chassis, it still has outstanding features that are not still used by Toshiba and Apple. However the only downside users might notice is its very short battery life but if you need an ultra-portable notebook then X301 makes a perfect choice for you.
