Core 2 Duo or "Conroe"
Without a doubt, Core 2 Duo or "Conroe" as it is code-named has been one of the most anticipated product launches in the hardware community for quite some time. Everybody has been waiting to see if Intel can claim back the performance crown and push under the rug the disappointment that was the NetBurst architecture.
Conroe is nothing like any previous Pentium 4 products. In fact, it's based on the mobile Core Duo design which is in itself based on Pentium M, which is based on Pentium 3 architecture. So Intel has actually done a bit of a U-turn.
Compared to Pentium 4, Core Duo (not to be confused with Core 2 Duo) offers low power consumption, low waste heat and high performance per clock. This is almost an exact opposite to the Pentium 4 which used so much power that the ATX specification had to be modified to add more 12V rails, and produced so much heat that they often throttled and made reaching 4GHz almost impossible. Not only this, but clock for clock performance wasn't stellar – hence the need for higher clock speeds in the first place. The resultant disparity between AMDs and Intel's clock speed was one of the primary reasons for AMD introducing PR ratings (eg. 5000+) so that consumers didn't feel like they were getting a raw deal.
Core 2 Duo is the next generation on from Core Duo. Although when tested the desktop "Conroe" version of the Core 2 Duo processor here today, there will be a mobile version code-named "Merom". Although this will be architecturally identical, it will have better power saving technology for extended battery life.
AMD's biggest selling point has been its on die memory controller. This has had a lot of knock on effects (such as almost identical performance from motherboard to motherboard), but the main effect is a huge reduction in memory latency as communication is no longer passed through the north bridge. This, in combination with HyperTransport reduced the bottleneck of the front side bus. Memory performance affects system performance significantly, so Intel processors were suffering in this area a lot.
Intel's solution to this is several minor improvements to the Core architecture in order to reduce this memory latency and increase overall system performance. Most of these optimisations are quite minor, but put together add up to more than the sum of their parts. Quite frankly, how Intel has improved their architecture so much is largely irrelevant - performance figures tell us all we need to know.
Possibly the biggest improvement is an added pipeline. Where as Core Duo can complete three instructions per cycle, Core 2 Duo can now complete four which an obvious increase in processing power and efficiency.
To help reduce bottlenecks, the front side bus has been increased to 1,066MHz from the 800Mhz that all but a few of the Extreme Edition processors used. This is at a base frequency of 266MHz, quad pumped.
If it wasn't completely obvious, the "Duo" portion of the name indicates that these are dual-core processors. Unlike previous Pentium D processors, these use a shared Level 2 cache (2MB or 4MB depending on the processor). This can be dynamically allocated depending on the task being run. For instance, if running an application that isn't multi-threaded (i.e. can't take advantage of a second core), then the primary core would get the full 4MB of Level 2 cache. Having more Level 2 cache means that fewer requests need to be made to the system memory – one of the biggest causes of latency.

AMD, Seagate 6Gbps SATA
AMD and Seagate teamed up to demonstrate next-generation transfer speeds based on the latest Serial ATA specifications. The new interface termed as SATA 6Gbps promises to offer twice disk-to-host bandwidth over existing SATA 3Gbps standard. The demonstration was on Seagate's Barracuda Serial ATA-600 prototype hard drive
The demo prototype was based on Seagate Barracuda 7200.12 drive that has a Serial ATA-300 interface. The SATA 6Gbps uses the same SATA 3Gbps connectors despite having fatter pipes.
The prototype Barracuda drive ran on AMD's chipset with a brand new storage controller. According to Seagate, the setup had hit a peak data rate of 589.09MB/s. AMD's south bridge SB750's successor will have full support for SATA 3.0 technology.
The specs include new goodness for a higher throughput peak by 200 percent. Recent destop drives pack 32MB NAND memory chips for supporting larger caches, which will boost the transfer speeds up to 250MB/s. The Solid State Drives on the other hand will move to 64NAND based on 34nm technology.
The SATA 3.0 standard is in final phase of development and isn't available on any product yet. However, Seagate expects to announce products compatible with SATA 3.0 by the year end.
AMD has announced the new ATI Radeon HD 4890 graphics card This is yet another high-end graphics card from ATI and the HD 4000 series card will be available for aproximate(Rs. 12,750).

ASUS F70
Asus has announced the F70 notebook, which it says is the first model available with a 17.3-inch display. This has LED backlighting, a 16:9 aspect ratio and a resolution of 1,920-x-1,080 to precisely match that a HD video.
The company says that the laptop's design is reminiscent of the Aurora Borealis (the Northern Lights), which sets it apart from conventional notebook designs. Not only is it designed to look beautiful -- it serves a highly practical purpose too by offering robustness against surface abrasions and maintaining the superb glossy appearance even after long periods of use.
The F70 notebook also integrates the 'chiclet' keyboard, a new generation of keyboard designed by Asus. The new keyboard features concave keys that fit the user's fingertips and offer a rebounding elasticity -- a design that Asus says eases the strain of typing over longer periods. Smaller spacing between keys also sees greater protection against the gathering of dust.
Other features include Altec Lansing surround sound speakers for HD audio, and an HDMI port for external displays.

Intel Xeon
At an event at the company's Silicon Valley headquarters, executives introduced the Xeon 5500 as a revolutionary product that serves as a 'future-proof' platform with 'intelligence built in' in the forms of increased speed and power efficiency.
Specifically, the company is pointed to technology within the chip that makes it more flexible while also offering faster speeds and more efficient use of energy. Intel highlighted some performance benchmarks, looked at specific servers, compared the performance against the previous generation chip, and found performance benchmarks that increased by more than 150 percent in some cases.
The company pointed to enhancements in the memory subsystem, as well as the I/O subsystems. It also noted improvements that will enhance virtualisation benchmarks.
Intel also promised the new chip will bring cost savings and significant return-on-investment for datacentres.
As IT departments see budgets and resources shrink, the main job has become management of the datacentre, leaving little time or money for innovation. Intel says the performance of the Xeon 5500 is such that IT departments will see an 90 percent performance improvement, compared to servers with single-core chip, as well as an 18 percent increase in energy efficiency.
On the stage, Intel drove home the point by stacking nine servers next to a single Xeon 5500 server that it said can do the same work better, faster and cheaper.
Already, companies such as IBM, HP, Dell and others are announcing their products built on the Xeon 5500 platform and are pushing many of the same themes: cost-savings, increased energy efficiency and improved performance.

Seagate BlackArmor
There are two network servers in the range: the BlackArmor NAS 420 network server and the BlackArmor NAS 440 network server. The NAS 420, which offers 2TB of storage for $799.99 (£549), has four bays — two empty and two fitted with drives.
The NAS 440 has four bays, all fitted with drives. The 4TB version costs $1,199.99, the 6TB version $1,699.99 and the 8TB version $1,999.99.
The products were most suitable for use in a company with around 50 employees, which puts them at the low end of the SME market. The products support Windows XP and Vista, as well as Mac OS X 10.4.11 or later.For security, they have individual file or entire volume encryption with software management for access control at file and folder level with password protection, Seagate said. They also come with a bare metal restore-and-recovery CD to protect against hardware failure.
The drives also have "continuous and automatic backup of business-critical data on up to 50 networked computers", Seagate said, with full-system backup and RAID options for data protection and redundancy.

AMD triple-core
Everything hasn’t exactly been great for AMD lately, but the plucky chip maker has some news for us today. Despite the tough times, the company earned a number of positive reactions from the recent 780G announcement, and it is following that up with three announcement today.
First, triple-core is finally here. We have been hearing about this for months, and after all complaints about triple-core being nothing more than failed quad-core processors, consumers will be able to find out for themselves. The triple core Phenoms will launch as mainstream processors, aimed at users who are interested in additional performance relative to dual-core offerings, without having to substantially increase the amount they are spending. AMD says that triple-core Phenoms will be ideal for budget-minded users who have high-definition content in mind, and that the processor will be a great match for 780G.
So far, we know about the Phenom 8600 (2.3GHz) and 8400 (2.1GHz). They will have L1 cache sizes of 64K of instruction and 64K of data cache per core (512KB total L1) and L2 will hold 512KB of L2 data cache per core (2MB total L2 per processor). These are 65 nm processors that are backwards compatible with AM2 motherboards. The TDP for both models is 95W. We are still waiting on pricing information, but it looks like they will be a bit over US$150.The next piece of news dropped concerned new quad-core processors, including the Phenom X4 9850 Black Edition and Phenom X4 9750. These are additions to AMD’s quad-core lineup that will run at 2.5GHz and 2.4GHz, with TDP ratings of 125W. The new in the 95W TDP are the 9650 and the 9550, which will come in at 2.3GHz and 2.2GHz. So, nothing groundbreaking, but the larger point is that AMD is aiming to make quad-core accessible, while maintaining it as the company’s high-end offering. A quad-core Phemon matched with the 790 chipset is the companies top-shelf offering for gaming, supposing you also pony up the dough for a competitive video card. These are bug-free B3 revision processors.

Basic tips for computing
Use strong words
A "strong" password mixes numbers and letters, and not in alphabetical or numerical sequence ("abcd1234" is not strong). Mix the case and throw in punctuation marks. Use an entire phrase if space allows; longer is better. PassPub.com randomly generates strong passwords you can use.
Don't use weak words
Never use a word that you can find in the dictionary or that is a proper name. Pets, kids, and spouses make bad passwords. Don't use the date you changed passwords ("jan23"). By all that's digital, don't use "password" as your password.
Change it
Alter your passwords regularly to stay one step ahead of those who might want to use them.
Be inconsistent
Don't use the same password on every computer you use or every site you surf. All it takes is one site to become compromised, and then someone will have access to all your accounts.
 |
For the memory challenged, create a single, strong password you can recall, then adjust it based on the name of the site or service. For MySpace, for example, "Blg1225" becomes "MyspBlg1225." Or let technology handle it: A number of Firefox add-ons will combine your master password with the name of a site to create a new password for each site.
Protect Firefox
The Firefox browser offers the option of a master password that you must enter before you can access any stored site passwords. It requires entering two passwords each time. The Mac OS comes with a feature called Keychain that holds passwords for Web sites, appli-cations, and more. You can find it in the Utilities folder.
Don't AutoComplete passwords
Browsers will not only store your passwords but also fill them in for you. This is a bad idea on a shared or office-based PC. In Firefox, use the master password instead. In IE, go to Internet Options, click the Content tab, and go to AutoComplete settings to disable.
Basic Tips
Install antivirus (AV)
Keep it up to date, run a regular scan, and let it check your incoming messages. Without this, your PC is virtually guaranteed to be infected.
Update antispyware
This may be bundled with your AV; keep it up to date and scan occasionally. It's a good idea to install a couple of antispyware apps, such as Windows Defender (it comes with Vista) and Spy Sweeper.
|
Prevent unwanted inbound and outbound traffic on your PC. Two-way firewalls come standard withMac OS and Windows Vista. Users of older Windows versions should get a third-party firewall such as CheckPoint's Zone alarm.
Don't mix multiple firewalls or antivirus software
It might seem like twice the protection to have two firewalls, but it's likely to double the headaches. Same with dual AV. (Antispyware is another story.)
Allow auto updates
Let Windows and Mac OS update when they want to, since Microsoft and Apple are constantly patching any security holes they find.
Don't accept EXEs
Downloading executable files (ending in .exe, .com, .bat, and .scr) is hard to avoid, but be wary of those e-mailed to you. That goes for .doc and .xls files as well; they can carry macro-based viruses.
Route traffic
If you have broadband service but don't have a router, get one. Wired or wireless, they're cheap.
Activate the hardware firewall
Your router should support NAT (network address translation) so Internet users scanning for open ports to exploit can't see your computers. It should also support SPI (stateful packet inspection) to distinguish legitimate network traffic from bad. Don't turn these features off.
Firewall Protection
The firewall is critical. A personal firewall's first task is to put all of your computer's ports in stealth mode, making it completely invisible from the Internet. Of course, it should allow necessary communication among the computers within your local network. This isn't tough; the built-in Windows Firewall can do it. But not all suites pass this simple test.
The firewall should also control outbound communication, preventing Internet access by unauthorized programs. The old-fashioned way to accomplish this was simple: When a given program tried to access the Internet for the first time, the firewall would ask the user whether or not to allow it. The problem is that most users aren't qualified to answer that question. Some products try to solve this problem by predefining access for hundreds (or thousands) of known good programs. That cuts down on the confirmation pop-ups, but doesn't eliminate them. Others, such as F-Secure Securitynet 2008 and Kaspersky Internet Security 7.0, "solve" the problem by running with this feature turned off by default—a poor choice.
The smartest firewalls use a three-part strategy. They automatically allow access for known good programs and delete known bad programs. When a program doesn't fit either category, the firewall keeps an eye on its behavior and allows access as long as the program doesn't try anything sneaky. Clearly this takes a lot more programmed-in intelligence than the simple ask-the-user plan, but it's definitely better for the user.Norton Internet Security 2008 and Panda Internet Security 2008 are two good examples of this approach in action.
There's always the possibility that malicious software will attack your firewall directly to disable its protection. Firewalls (and security programs in general) should resist if malware tries to kill their processes, turn off their services, or otherwise disable the protection they offer.
Your firewall may or may not protect directly against Web-based attacks that exploit vulnerabilities in the operating system or browser. Some, like NIS 2008, actively block exploits and even identify them by name. But most rely on their malware-protection abilities to prevent the exploit from doing harm, even if it does manage to plant a malicious file on your computer.
The versatile 22-inch HDTV/monitor from ViewSonic
Designed for use in tight spaces, theViewSonic N2201w is ideal for dorm room or studio apartment living, or if you simply want to add a TV to your already-cramped home office. This versatile 22-inch HDTV/monitor hybrid sports a variety of entertainment features, including a built-in DVD player and a digital TV tuner, but its dark grayscale performance is lacking.

The 1,680-by-1,050 resolution panel, housed in a black cabinet with a shiny black bezel, is perched atop a wide oval base, which gives it a good measure of stability. Unfortunately, the stand is a tilt-only model that lets you angle the panel forward but not backward beyond the 90-degree point, and it doesn't support height or swivel adjustments. If you do decide to tilt the screen, make sure you use both hands, as the mechanism is very stiff.
The 3-watt speakers embedded in the lower bezel are a cut above the usual underpowered speakers found on displays. They are loud and deliver a full range of high and midrange tones. You won't get booming bass from these speakers, but they do produce more bottom than most.
Around back are a slew of connectivity ports, including a standard VGA analog port, an HDMI port, component video and audio outputs, S-Video and composite video inputs, 2-channel audio inputs, a digital audio output, and a coaxial TV antenna/cable input. There's also a DVD video output for playing videos on an external screen. Considering the lack of a DVI port, a second HDMI port would have been nice, but this is still a good mix of ports for a 22-inch monitor. The N2201w comes with a VGA cable, but you're on your own when it comes to HDMI, S-Video, and component cables.
A slot-loading DVD player with five control buttons, clearly labeled with white lettering, is integrated into the left-hand side of the cabinet. Below it is a conveniently positioned headphone jack. The same white lettering is used to identify the seven buttons (including the power switch) on the right-hand side of the display, one of which is a Menu button that takes you into the on-screen display (OSD) system. The other buttons are used to change TV channels, select an input source, and raise or lower the volume. They can also be used to toggle through and select menu choices while navigating the OSD, but it's much easier to use the included full-function remote, which features the usual array of TV and DVD player controls as well as closed captioning, favorite channels, MTS/SAP, and electronic program guide buttons.
While in PC mode, you can adjust contrast, brightness, and sharpness, and toggle between four Picture modes: Standard, Dynamic, Soft, and Personal (user-defined). I'd recommend sticking with the Standard setting, as Soft was very dark and Dynamic a bit too bright. Color temperature choices include Cool, Warm, and Normal, and you can adjust horizontal and vertical positioning and clock and phase levels. The same settings are available in TV mode, where you can select a TV signal source, scan for available channels, enable closed captioning, and set parental controls as well.
I was generally impressed with the L2201w's performance as a PC monitor. It did a very good job of reproducing the lightest shades of gray on my DisplayMate 64-Step Grayscale test. Colors were bold and uniform at the high end of the scale. The panel had a difficult time displaying the darkest shades of gray, however, making the deepest reds and blues darker than they should be. There also was noticeable backlight bleeding along the bottom edge and left-hand side of the panel. Still, color representation was generally good, and text was crisp and well defined at 6 points. Smaller fonts set to 5.3 points were slightly fuzzy but still legible.
The integrated ATSC/NTAC/QAM tuner's auto-scan had no trouble finding all of my available cable channels, and they all came in cleanly. Channel changing via the remote was a tad slow, but not unbearably so, and the 5-millisecond (black-to-white) pixel-response rate provided smooth motion handling. Using the HDMI port to connect to my cable box, I watched Sunrise Earth on Discovery's HD Theater channel, which comes in at 1080i. The picture was sharp, with no apparent jaggies or artifacts, and colors were very bright without appearing oversaturated. There was some loss of detail in darker scenes, which can be attributed to the dark grayscale flaw. The integrated DVD player performed flawlessly, but on several occasions the monitor was unable to sync up when I switched back to PC mode, requiring a reboot.
The ViewSonic L2201w is not without its flaws, but given its affordable price, it's a good deal for a display that pulls double duty as a PC monitor and an HDTV/DVD player combo.
HP Flies Fast with Stylish Firebird PC
HP is introducing the "HP Firebird with VoodooDNA" 802 and 803 PCs, which will be featured at the CES 2009 show this week in Las Vegas.
Both Firebirds join the Voodoo omen and HP's Blackbird gaming PCs, as a more compact gaming PC for 2009. Both versions of the Firebird are style-forward, eschewing the blocky gaming tower of the past: the Firebird has a slimmer, floating design ID that evokes the Blackbird while keeping the slim theme. Like the Blackbird, the Firebird is easy to get into and service, though the slimmer chassis predictably has less expansion space.
The Firebird centers around a quad-core Intel Core 2 Quad processor (liquid cooled, naturally), dual Nvidia GeForce 9800S graphics cards in SLI configuration, and 4 Gbytes of DDR2 memory. The 802 comes with a Core 2 Quad Q9400 processor, 500GB (2 x 250-GB) hard drive capacity, and a slot-loading DVD burner. The 803 comes with a faster Q9550 processor, 640 GB (2 x 320GB) hard drive capacity, and Blu-ray player/DVD burner combo drive (also slot-loading). The Firebird's power supply is external, which saves space in the chassis, while giving the Firebird better power efficiency than other gaming desktops.
Both versions of the Firebird come with a wireless keyboard and mouse sets to keep the lines clean. The 804 also comes with 802.11 b/g/n wireless networking and Bluetooth, which can help reduce clutter even further. The Firebird's hard drives are 2.5-inch notebook class hard drives, saving space in the design-forward chassis. I see this system, which will start at $1,799, slotting in between the mainstream multimedia PCs from HP and the high end gaming PCs from HP and Voodoo.
