Sony Ericsson has finally launched the much awaited Xperia X10, Xperia X10 mini, Xperia X10 mini pro, Vivaz, and Vivaz pro in India.

The new portfolio also introduces a new UX platform that creates a unique Sony Ericsson user experience by combining best-in-class entertainment features with signature applications, unrivalled integration of social media services and a rich graphical user interface. Among the many new features, the new phones introduce signature applications like Mediascape and Timescape that lets consumers organise everything in their phone in an intuitive way.

Sony Ericsson has also partnered with regional and local content and application providers to deliver the latest in entertainment content for consumers. Highlighting one such exclusive partnership, Mr. Ishizuka said, “We have a signed a regional partnership with MTV, whereby the Xperia X10 users will have exclusive access to the MTV application that will provide them news feeds and other updates from the channel.”

Sony Ericsson is also partnering with content and application providers to deliver the latest in entertainment content for consumers. This includes players such as Hungama, MTV India, UTV, Shemaroo, Electronic Arts, Indiagames, and Disney mobile among others, who will come together with the mobile phone brand to offer content and applications to Sony Ericsson users in India.

The Vivaz Pro adds a QWERTY keyboard to the touch screen offering to deliver a user experience optimized for messaging and entertainment. Like it’s big brother Vivaz, the Vivaz Pro also allows consumers to produce and broadcast their best experiences in HD video, viewed on the 3.2″ 16:9 wide touchscreen.

Like before the handset will come with a dataplan and will be locked to the network providing the handset for a year. In this case it still isn’t clear which service providers will be offering the iPhone 3GS.

The iPhone 4G is all set to hit the US market and we still haven’t gotten 3G in India barring MTNL and BSNL.

The Google Nexus One though is expected to be launched here albeit in a stripped down avatar.

Core i7: The new super CPU

Article courtesy Chip
Chip czar Intel has once again set new benchmark records with its latest CPUs, the Core i7 series. CHIP reveals the technical innovations inside them.
Intel’s development model for processors is known as the “Tick Tock” cycle. Every alternate year, they focus is on miniaturizing the existing production technology for CPUs (known as a process shrink—“Tick”), while in the next year a new architecture will be introduced, based on this process (“Tock”). The system has been functioning well for four years now. The Core i7 architecture, formerly known by its codename “Nehalem”, was introduced in November 2008, after the original Core architecture was shrunk to 45 nm around the end of 2007 (products codenamed “Penryn”). The new design brings a series of changes with it, all aimed at optimizing performance, power consumption and reliability.
New package
The last time Intel changed its processor package was in 2004, when it went from 478 contact pins to 775 pads. Since then, the package and matching socket has remained the same despite many CPU refreshes, but now Nehalem requires a radical turnabout. The new CPU requires about 600 more pins for all its new functions. Core i7 CPUs won’t fit into older motherboards since they now have 1,366 contact pads instead of 775. Even if they did fit physically, nothing would work since there are many new elements on the CPU which need to be connected to the motherboard and the rest of the computer’s components. The transition is understandable since it’s been a long time and there are genuine needs and advantages, but anyone who wants to use the new Intel technology must buy a new motherboard.
Goodbye FSB
The most significant innovation with the Nehalem architecture is the obsolescence of the Front Side Bus (FSB), which has been responsible for all communication between CPU and chipset so far. Its successor is known as the QuickPath Interconnect (QPI). The FSB was replaced mainly because its bandwidth was found to be inadequate: QPI provides 20-bit wide, bidirectional links resulting in a maximum data rate of 25.6 GB/s. This is immediately twice the speed of what an FSB at its highest possible rating of 1,600 MHz could offer. QPI is very similar to the HyperTransport technology used by AMD since 2001, which is now at version 3.1 and achieves similar transfer rates.
Intel has chosen to adopt another technique very successfully applied by AMD: a memory controller integrated in the processor package. Intel’s desktop architectures until now have placed the memory controller in the chipset. The specialty of current high end Core i7s is their triple-channel memory controller. Three memory modules can now be ganged up to achieve data transfer rates fast enough to keep the CPU fed with fresh data so that its potential is used optimally. The result is that PCs which make use of this will have 3, 6 or 12 GB of RAM, which is unconventional compared to the progression we’re used to. However, lower-cost Nehalem CPUs which are yet to be launched will feature more traditional dual-channel memory controllers and a different, smaller socket with only 1156 contact pads.

New design: Small L2 cache and large common L3 cache
One of the weak points of the cache design on Intel’s previous CPUs was that on a quad-core CPU, each pair of two cores shared a 6 MB L2 cache which was exclusive to them. This was great for fast data exchanges between those two cores, but bad for exchanges between all four, which required the data to travel through the much slower Front Side Bus. In Core i7 CPUs, each core now has its own L2 cache, which is considerably downsized to 256 KB, but with its speed increased by 50 percent. Like in AMD’s  Athlon CPUs, a common 8 MB L3 cache (for the current quad-core models) is added to enable data exchange between the cores. This cache receives all data from the cores’ L1 and L2 caches, which in turn considerably accelerates data processing. This allows each core to be shut down without any risk of losing data that’s in transit between caches.
A CPU design for all applications
The scalability of the Core i7 architecture is quite unique. Nehalem is suitable for desktops, servers and notebooks as well. Thanks to the new cache design and the introduction of the QPI, two, four or eight cores can now be integrated in a single processor die. Furthermore, the high speed of the QPI enables quick communication between several CPUs on one motherboard for high-end and server configurations. When 8-core Nehalem chips are available, power users should be able to gang two of them up for a grand total of 16 cores and 32 virtual CPUs!
At present, three Core i7 models are available in the market, with more to come soon. By the end of the year 2009, lower cost versions of Nehalem (codenamed Lynnfield and Havendale) will hit the market, with many more innovations and performance advantages in store for users.
