Technology Trends of 2009

Every body wishes to get new things whether it is in accessories, clothings, jewelry trends or in technology. So let us discuss the expected things from technology this new year. All of us know Vista was a great failure in 2008 but Microsoft is working hard on its successor now, i.e,Windows 7. If the final thing in hand will be the beta version then it will be a great thing and the efforts will lead to good fruit. It will support native reading and writing Blu-ray discs. It will provide a new platform for interaction with removable devices and support virtual hard Drive images. Also it is expected to have better backup and restore mechanisms. New version will have Seamless audio transfers to Bluetooth 2.1 audio devices. Along with this, there will be inbuilt support for many GPS positioning sensors. It is also said that the new Windows 7 will be better in remote computing too which will facilitate in accessing your desktop from anywhere in the world. Windows 7 will have UAC with simpler, clearer and fewer messages. Despite of these it will also have faster booting and shutdown.

PC memory is such a thing which is always more in demand.. It has gone down the trend in cost last year but its expected that similar trend won't be there this year. According to the drift of last year it is likely to have 4GB memory by the end of 2009 as mainstream and the servers are expected to get 8GB modules or even higher than that. However, since 4GB is the limit for 32-bit versions of Windows, and applications have limitations for the maximum amount of memory they can use effectively, we would like to be cautious and refrain from speculating whether they will become popular or not. Because of the above fact, it will be a waste to run in dual or three channel configuration using larger modules when 32-bit OS cannot access it. Now a days CPUs have also started moving to DDR3 and DDR2 but it is likely to be phased out by the end of this year because the memory controller is on CPU. Previously this feature was with AMD but now Intel has jumped onto the movement along with Core i7. It is also said that the forthcoming AM3 from AMD will keep on supporting DDR2 memory along with DDR3 but in-spite of this it is expected that maximum market-share will belong to Intel. Actually chip-set never matters for any kind of memory to be supported. As the Core i7 supports three channel memory, so there will be memory kits with three matched memory sticks in the market in year 2009.

Processors is such a field in which there is always something to do new and it is the most important field for computing too. At the end of year 2008 Intel launched Core i7 previously named as Nehalem. As per Intel's “tick tock” model, Nehalem is a "tock", 2009 will be a "tick", this means that a new fabrication process will be used. The motive of this processor was to have high performance servers. Now in the second half of this new year it is expected that its desktops and laptop versions will be available. The biggest architectural advance Intel was Pentium4 made in 2000 and was known as Heralded. Its architecture is scalable from two to eight cores. It uses Hyper Threading technology. Right now it is only on few Pentium and Xeon processors, allowing two threads per core. It provide improved performance per clock speed with energy efficiency. It also provided better sleep facility with Turbo mode. Cores didn't consume any power in this mode and hence could be shut down completely while the predecessors used to consume power. So to avail improved and better performance for applications which do not support multi-threading, Core i7 boosts up the clock speed of the left out cores but retaining the chip within the design power consumption limits. On the failure of IDF 2007 it was observed that Tukwila wafer was based on 32 nm and in this coming year it will be introduced for desktop processors.

Also as there will be improvement in Intel processor this year similarly there is an expected improvement scope in AMD processors. It has been specified that there will be soon a change in 45nm technology. AMD is going to be shifted on Socket AM3 (45 nm)which was expected to be released in December 2008 but will be released this year in January 2009 because of the scheduled release of socket AM2+ processors in the first week of this month. It will be having two pins less than AM2 i.e there will be 938 pins in total. Because of this change in socket older processors become incompatible with the new socket. It has also been declared by AMD that AM3 processors feature memory controller supporting both DDR2 and DDR3. Also AMD will take along six-core processors so as to join its triple-core and quad-core phenomena parts. Contrasting Intel, they refuse to go along rating and promoting processors according to clock speeds.
