Intel Corporation has launched its most advanced desktop processor ever called the Intel Core i7 processor. Intel Core i7 is a family of three Intel Desktop x86-64 processors, the first processors released using the Intel Nehalem microarchitecture and the successor to the Intel Core 2 family. All three models are quad-core processors.It was officially launched on November 17, 2008.
Intel Turbo Boost Technology automatically adjusts the clock speed of one or more of the four individual processing cores for single- and multi-threaded applications to boost performance. The Core i7 processor more than doubles the memory bandwidth of previous Intel “Extreme” platforms, speeding the transfer of computer bits and bites in and out of the processor with Intel Quickpath Technology. Intel’s Hyper-Threading Technology allows multiple computing threads to run simultaneously, effectively enabling it to do two things at once, so the Core i7 quad-core processor delivers 8-threaded performance.
Each Core i7 processor has an 8 MB level 3 cache and three channels of DDR3 1066 memory to deliver the best memory performance of any desktop platform. Intel’s top performance processor, the Intel Core i7 Extreme Edition, also removes overspeed protection, allowing further increase in the chip’s speed.

A 2.93 GHz Core i7 940 system has been used to run a 3DMark Vantage benchmark and gave a CPU score of 17,966.[15] The 2.66 GHz Core i7 920 scores 16,294. An earlier generation Core processor, the very expensive 3.20 Ghz Intel Core 2 Extreme QX9770, scores 13,182. Another one, the 2.66 GHz Core 2 Quad Q9450, scores 11,131.
Over-clocking will be possible with the 900 series and a motherboard equipped with the X58 chipset. In early October 2008, reports surfaced that it will not be possible to use "performance" DDR3 DIMMs that require voltages higher than 1.65v, because the integrated memory controller within the Core i7 will be damaged.[18] Some tests, however, have demonstrated that the voltage limit does not apply, like on a MSI board, and manufacturers can choose to bond CPU voltage to memory or not. By the end of that month, performance memory vendors had announced 1.65v DDR3 memory kits with clock rates up to 2GHz.
he Intel Core i7 is also a very good match for extreme gaming platforms, especially heavy Multi-GPU environements that require a tremendous amount of CPU power, so the Core i7 965 Extreme Edition can provide incredible gains over Intel's previous fastest CPU: the Core 2 Extreme QX9770.Now play Crysis like never before.
Intel Core i7- 920 starts at $284, Intel Core i7-965 Extreme Edition will cost $999. But the prices are expected to come down in next 4 to 5 months.
And OEM`s may start shipping systems with core i7 extreme by the end of 2009.
Keyboardr is a new way to search for your queries over the web. It searches as and when u type(It shows u the search result after u entered each character and u need not to press enter). U must have noticied it in the Windows Vista, Its a bit slower in vista but faster in apple`s mac.
The best part of the keyboardr is that it shows u the results of google search engine, google blogsearch,youtube and google imagesearch and wikipedia in a single page and u can use arrow key to navigate among the results
U can see the screenshot of keyboardr when i tried for the keyword "RVCE"

R u puzzeled to see those ratings.
Yes,, its the rating shown by windows vista in my computer.
U can hack it and and change them to the watever numbers u wish.
Just follow the steps given below
1. Navigate to C:\Windows\Performance\WinSAT\DataStore.
2. Open up the most recent file in that folder. Make sure that your account has write access to that file. If not change the file permissions.
3. Parse the file looking for the WinSPR entry. These are the items you want to edit. The maximum value you can use is 9.9.
4. Save the file and you just turned your 2.1 system into a supercomputer.
Many people who got disappointed with vista(not really me) are hoping that Windows 7 will bring dramatic changes to Windows, they may well be disappointed. More and more evidence shows that Windows 7 may only be the equivalent of a Vista SP2.
Microsoft is being remaining silent about what will be in Windows 7, but it looks as if no major changes are in the offing. Microsoft has said that it's not developing a new kernel for Windows 7, and it has said that the hardware, software, and peripherals that work with Vista will also work with Windows 7.
Microsoft has said that Windows 7 will include something called pervasive multi-touch. That's a fancy way of saying that you'll be able to run the operating sytem and its underlying applets via a touch screen.
That certainly doesn't get me excited. Microsoft has been touting touch screens and pen computing for as far back as I can remember, and no one seems to care. Sure, it will help with specialized applications, but for most business and home users, it simply doesn't matter.
Windows 7 may ship with a new version of Internet Explorer such as internet explorer 8(if microsoft is able to release the full version by that time which is currently in beta state) and isn't necessarily tied to the operating system.
No doubt, there will be other changes as well. But if the kernel isn't being rewritten, and if all existing Vista hardware and software will work with Windows 7, there's a good chance you won't see any major changes to Windows.
Windows XP SP2, you may recall, added considerable new features to XP. It finally gave a firewall to Windows, introduced a pop-up blocker, introduced better wireless access and security, and more.
Those are all very significant changes --- and it's not clear that Windows 7 will offer as many new features as even SP2 did for XP.
So why bother giving the new version of Windows a new name, instead of calling it a Service Pack? Because Vista has gotten a tremendous amount of bad press, and this will be a way for Microsoft to put that behind it.
I hope that I'm wrong, and that we'll see plenty of new features in Windows 7. After all, we're still about a year-and-a-half away from shipping. But the signs right now don't look good.

On September 18, 2007, Pat Gelsinger demonstrated USB 3.0 at the Intel Developer Forum. USB 3.0 is targeted at ten times the current bitrate, reaching roughly 4.8 Gbit/s (for a highly theoretical maximum 600MB/s) by utilizing two additional high-speed differential pairs for "Superspeed" mode at a clock frequency of 2.5GHz , and with the possibility for optical interconnect. The two new differential pairs make the cable about as thick as an ethernet cable and provide full-duplex transfers.[32] The USB 3.0 specification was 90% complete as of August 13, 2008[33] and commercial products are expected to arrive in 2009 or 2010.[ USB 3.0 is designed to be backwards-compatible with both USB 2.0 and USB 1.1 and employs more efficient protocols such as 8b/10b encoding to conserve power while increasing the maximum power available for connected devices.
USB 2.0 cables worked off of four lines – a pair for in/out data transfer, one line for power, and the last for grounding. USB 3.0 adds five new lines (the cable is noticeably thicker), but the new contacts sit parallel to the old ones on a different plane, as opposed to being adjacent to them. This means you’ll be able to differentiate between 2.0 and 3.0 cables just by looking at the ends.With USB 3.0, two new lanes will be dedicated to transmit data, while another pair will handle receiving data. This not only accounts for the significant speed boost, but also allows USB 3.0 to both read and write at the same time from your portable storage device. In the old spec, the pair of lanes used for data transfer weren’t split between send and receive – they only could handle traffic in one direction. Bi-directional data transfer will be very useful for syncing up information on PDAs and storage backup. They’ll carry more power, too. The USB-IF recognizes the growing number of portable devices that charge via USB (cellphones, MP3 players, digital cameras), and have bumped the power output from about 100miliamps to 900 milliamps. That means not only will you be able to power more than 4 devices from a single hub, but the increase current will let you charge up heftier hardware as well.
Like the upgrade from USB 1.1 to 2.0, the new 3.0 connectors and cables will be physically and functionally compatible with hardware from the older specs. Of course, you won’t be able to maximize your bandwidth unless you’re using a USB 3.0 cable with Superspeed devices and ports, but at least plugging a 3.0 cable into a 2.0 port won’t blow up your PC. The spec’s compatibility lies in the design of the new connectors
According to electronicdesign.com cables will be limited to 3 m at full speed. The technology is similar to PCI Express 2.0 (5-Gbit/s). It uses 8B10B encoding, linear feedback shift register (LFSR) scrambling for data, spread spectrum. It forces receivers to use lowfrequency periodic signaling (LFPS), dynamic equalization, and training sequences to ensure fast signal locking.
The connector will be divided into two parts. The first part is the USB 2.0 four-wire version with UTP data pair and power with ground. The second part will have five connections: two UTP lane (one is uplink and one is downlink) and a ground. An optical connector and cable will be available in the future.
