AMD chips top 8.4 GHz, a new speed record...!!!

 
AMD said Tuesday that the company's FX processors had been overclocked to an astounding 8.429 GHz. AMD said in a blog post that the eight FX processors had been overclocked at speeds up to 8.429 GHz, beating the prior record of 8.309 GHz, using a third-party team of overclocking enthusiasts. More importantly to the average consumer user, however, AMD found that the company's FX chips could reach over 5 GHz using normal air cooling or water-cooling rigs that cost less than $100. 
 
"Based on our overclocking tests, the AMD FX CPU is a clock eating monster, temporarily able to withstand extreme conditions to achieve amazing speed," Simon Solotko, a senior manager with AMD, wrote. "Even with more conservative methods, the AMD FX processors, with multiplier unlocked throughout the range, appear to scale with cold. We also achieved clock frequencies well above 5GHz using only air or sub-$100 water cooling solutions."
 
 
 
Guinness is expected to certify the record, an AMD spokesman said Tuesday. AMD's announcement opens the Intel Developer Forum here in San Francisco, a developer conference hosted by AMD's arch-rival and much larger competitor, Intel.
 
What is overclocking? Historically, overclocking was a practice begun in the early days of the 486 and Pentium where a microprocessor was pushed past its rated speeds. Microprocessors are generally "binned," where each chip is tested to determine the fastest speed at which it can operate before it starts generating electrical faults and/or incorrect results due to the heat it itself produces. Within a PC, notebook computer or phone, these chips are generally either air-cooled using a series of "fins" that distribute the chip's warmth to the outside air via a fan. A sealed network of tubes, filled with water, can also be connected to a copper-based "heat sink," which thermally conducts heat away from the CPU.
 
Overclocking a chip can void its warranty, however, meaning that it's generally a risky practice even for enthusiasts. An overclocked chip that fails can essentially be destroyed, as can the motherboard or chipset components.
 
Extreme overclocking uses liquid helium and nitrogen to cool the chips; liquid nitrogen can push the chip's temperature down to less than negative 180 degrees centigrade. The risk here is a "cold bug," which can also prevent the chip from working. Fortunately for AMD, the team of overclockers found no such bug.
 
AMD's FX chips represent its enthusiast line of high-end chips, which are "unlocked," allowing users to set its operating voltage and clock speed multiplier in order to overclock the chips.
 

Nvidia releases the five-core Tegra 3 chipset....!!!

Nvidia has launched the much-awaited quad-core Tegra 3 chipset, codenamed Kal-El, destined to arrive in the Asus Eee Pad Transformer Prime later this month. According to the graphics giant, the Tegra 3 chipset is based on 40nm fabrication technology, and is expected to deliver five times the overall performance of the Tegra 2, and roughly three times the graphical performance, all while using about 40 percent of the Tegra 2’s power. While the Tegra 3 is meant primarily for the Android operating system, it also supports Windows 8 and Chrome OS.


The Tegra 3 will officially be the first ARM-based quad-core chipset to begin shipping, though others chip-makers, like Qualcomm, Texas Instruments, and ST-Ericsson are also expected to unveil quad-core ARM offerings by 2012. While called a quad-core, the Tegra 3 actually contains five general processing ARM Cortex A9 cores, with the lower-clocked 500MHz fifth ‘companion’ core taking care of most non-intensive tasks for the system, to save power. The other four processor cores can run at a maximum core clock of 1.4GHz (up from 1GHz of the Tegra 2), though if all the cores are active at once, that figure drops to 1.3GHz.

The resource allocation is apparently “OS transparent”, meaning the operating system will not have to be modified to support Nvidia’s Variable Symmetric Multiprocessing (vSMP) technology, which chooses which cores to activate. In low power mode, only the companion core will be running.

Check out a schematic of the die below (sized roughly at 80mm2), with the various components highlighted.
 
The Tegra 3 GeForce GPU features 8 pixel shader units, four vertex shader units, and 12 GPU cores, each with a larger cache than what the Tegra 2 had. For now, Nvidia has not confirmed the clock speed of the GPU cores, or how much higher it is than the Tegra 2’s 300MHz offering. The biggest graphical improvements with the Tegra 3 chipset include the ability to realistically render water simulations, smoke, blurs, damage, and lighting.

The new Tegra 3 also supports stereoscopic 3D, and, features expanded controller support for PS3, Xbox 360 and Wii controllers. According to Nvidia, the Tegra 3 also features an improved video decoder and encoder, which can accelerate 1080p H.264 content to up to 40Mbps, and encode 1080p video at 30fps. Also new, is the Image Signal Processor (ISP), which is supposedly twice as fast as the one on the Tegra 2.

Still featuring a 32-bit memory interface, the Tegra 3 supports higher-frequency memory however, up to LPDDR2-1066MHz and DDR3-L-1500MHz. The SATA II controller is now on die. Looking at the recently released roadmap, the Kal-El's successor, Kal-El+ is expected to be released by mid-2012, before Wayne or Tegra 4 hits shelves in 2013. For now, while Nvidia hasn't drastically improved per-core performance compared to the Tegra 3, subsequent iterations are expected to start doing so, starting with Wayne. In the meanwhile, the Tegra 3 will still pack a punch, according to AnandTech's Mr. Shimpi, "Tegra 3 attempts to increase performance by exploiting thread level parallelism in Android."

Apple TVs to come in three sizes....!!!


There’ve been quite a few rumours of Apple working on developing a Apple-branded TV set, not just the relatively popular Apple TV set-top box it’s been selling in the recent past. Now, a report by Australian technology blog Smarthouse, says that it has confirmation of this, via sources at a major Japanese television manufacturer.

The report goes on to say that Apple will be releasing three sizes of televisions when it launches in late 2012, with 32-inch and 55-inch versions described. As for the third size, something smaller seems likely, probably a 24-inch offering. 

According to the sources quoted, Apple TVs will feature Siri integration, taking the fight to other smart, connected TVs out there, by such companies as Samsung and LG. Relevantly, Microsoft recently announced voice-based search for the Xbox 360 platform, powered by Bing and Kinect, as well as entertainment options, all of which will make Xbox TV a potential competitor as well, though more as set-top box.
As for branding, so far, industry speculation is rife with names, with iTV seeming like the most popular choice. This may of course cause trademark problems, as other iTVs exist across the world already.

Nokia Lumia 800 Review.....!!!

It was a long wait for the first Nokia smartphone with Windows Phone OS. And we believe that wait has been a long but successful one. The Lumia 800 seems to be a well designed package - with looks far superior than any other WP phone out there, an excellent display, good battery life and a UI that is thrashing Android’s ageing UI hands down. Critically, it again boils down to the pricing bit, and we hope Nokia gets it right.


Pros:
  • Unique yet brilliant design
  • Classy yet solid build quality
  • Excellent UI on WP 7.5 - Live Tiles particularly
  • Very good display - particularly for multimedia consumption
  • Contact handling much improved with Mango update
  • Battery life doesn't disappoint

Cons:
  • Call clarity isn't as good as we had hoped for
  • Accessing the micro SIM slot is an unnecessarily long process
  • Disappointing camera
 It is finally here. We have been waiting since the February announcement for a Windows Phone from Nokia. And we must admit, we were quite apprehensive about how good the smartphone would be. Safe to say, those apprehensions seemed to evaporate rather quickly. To be precise, after a couple of hours of playing with the Lumia 800!
Look & Feel

The Lumia 800 does carry a lot of design traits from the N9. All the four edges are curved, and the back is slightly sloped near the top and the bottom - ever so slightly. Below the 3.7-inch display are three touch buttons - return, home (familiar Windows Logo on it) and Bing search. The only three physical buttons on the entire handset are on the right side panel - volume rocker, camera and the power key.
On the top are the 3.5mm jack and a bunch of flaps that cover the micro USB port and the micro SIM card slot. Opening this is a bit of a pain though - not because it is difficult but because of the sheer wastage of time. First, press one flap down, marked by a bulge, enough that the other end lifts up. Once that happens, open it completely. Now turn your attention to the SIM card slot. For this, slide the panel slightly towards the USB port, and then pull it out. Don’t really understand the entire complication. Separate handling of the two ports would have been better - time saving as well as longevity of the loving parts. Flip the phone to the bottom panel and there is the speaker. No other moving parts on the phone, since even the battery is closed away and cannot be accessed.
The Lumia 800 seems to have a lot going for it, design-wise. It feels good to hold, has a nice sophisticated feel and minimalist looks as well.

Features & Performance

We had criticized Nokia quite a bit recently for launching very good yet under-powered phones - the Nokia E6 being a good example. However, that seems sorted now. The Lumia 800 comes with a Qualcomm Snapdragon MSM8255 processor clocking at 1.4GHz on a single core. There is 512MB RAM to help move things along as well. The single core processor will surely raise a few eyebrows, particularly if this is priced in the same bracket as some well established dual core Android phones and the iPhone 4. This neatly brings me to my next point - Windows Phone Mango doesn’t need any more grunt than this, or so it seems. We have seen this OS in action on the older gen Samsung Focus smartphone, as well as the newer ones - the Samsung Omnia W and now this. The interface is zippy, transitions are silky smooth and the phone doesn’t slow down at all. Quite creditable considering the host of 3D effects in the menu.
The 3.7-inch display is the AMOLED type with a resolution of 480 x 800. This display type is similar to the one we saw in the Samsung Galaxy SII, albeit a smaller size. The darker colours in an AMOLED display draw lesser power. Apart from the battery life benefit, it results in really dark black levels. The rest of the colour bunch is quite vivid as well. Brightness levels are extremely good as well, and even at low brightness settings, it is comfortable for indoor use. The display isn't very reflective, which helps a lot in viewing the text in sunlight. Windows Phone 7.5’s UI looked absolutely gorgeous on this display. The rich colours and the deep blacks mean that viewing videos or reading text on this display will be a delightful experience.
There is 16GB storage built-in on the Lumia 800, but no memory expansion slot.
Contact handling has been improved extensively with the mango update. Now, you can even transfer all contacts from any phone to the Lumia via Bluetooth. We tried this with a Blackberry phone, and all 750 contacts were transferred to the People list on the Lumia, complete with any tagged images.
Disappointingly, the call quality of the Lumia 800 wasn’t as brilliant as we had hoped for. The clarity was just not there, and it was particularly difficult to hear the other person if you or the other person happen to be in a noisy place. Also, if the signal strength isn't perfect, there will be noise within the call. No problem with the earpiece loudness though.
The disappointment continues on the camera front. First off, there is no front facing camera. That means, video chats are out of the question. Secondly, the 8MP camera is extremely finicky when it comes to lighting. If the lighting is perfect, then the shots that you take will be quite good. However, if you are taking a shot in less than perfect light, or even indoors, then the images will be ruined by the noise. The camera takes time to focus, particularly when taking close-up shots. This snapper can record 720p HD videos, and the quality is quite satisfactory. There is quite a bit of sharpness, but there tends to be a ‘de-noise’ effect on some details when panning.
But what is really going for the Lumia 800 is the operating system on board. Windows Phone 7.5 looks absolutely gorgeous. We had said this earlier, and will say it again, “WP.7.5 is kicking Android hollow as far as UI slickness and an intuitive feel is concerned”. We feel that post the Mango update, only the iOS 5 is better in terms of the slickness, with WP 7.5 in a solid second place. The Live Tiles are an excellent add-on, particularly when you consider that it isn't demanding a high spec hardware package to do all that. The Xbox Live tile, People and Gallery keep getting updated with new elements at regular intervals - usually a few minutes. If you add the weather tile as well, that keeps getting refreshed as well. It is an interesting sight the moment you slide the lock screen upwards!
Nokia have preloaded the Lumia 800 with a couple of their own apps - Nokia Maps and Nokia Drive. The Maps application asks you to download global maps - well you can select which ones you want, and the navigation voice as well. Downloading these helps improve lock-on and navigation speeds. Nokia Drive is the turn-by-turn navigation app that is useful if you rely on your phone to be the GPS device sometimes.
We must say this - the battery life of the Lumia 800 is impressive. Despite constant connectivity to the Internet, a bunch of calls, messages, and lots of web browsing, the battery lasted 2 full days on a single charge. Admittedly, we were in the initial excitement phase and using the phone a bit more than most people normally would!

Our Take
In terms of the package, the Lumia 800 has the hardware, the performance and a very good OS. It does miss out on a memory card slot and a front facing camera. We just hope Nokia get the pricing right, and don’t overprice it.

Price:28,000 Rs.

Specs:
Qualcomm MSM8255 Snapdragon 1.4GHz processor; 512MB RAM; Windows Phone 7.5; 3.7-inch AMOLED display, 480 x 800 pixels; 16GB storage; 8MP camera with 720p HD videos; micro SIM slot only; 1450 mAh battery

Symbian Belle update for Symbian^3/Anna devices coming in early 2012....!!!

Nokia is going to start rolling out Symbian Belle update to its Symbian^3/Anna smartphones, including N8 and E6, by early 2012. Though Nokia has not specified any release date, the update is expected to arrive by February next year. Earlier, the update was expected to be available before end of this year but apparently that's unlikely to happen.

According to an All About Symbian report, Nokia has confirmed the availability of Symbian Belle update sometime in early-2012. The report also quotes an official statement from Nokia which is as follows:
"Nokia Belle is the latest Symbian software release with all-new user interface, improved user experience, and dozens of improved and new features. We have already shipped Nokia 603, 700 and 701 with Belle software this year, and have received great feedback on the new user experience.
We will make Nokia Belle available to consumers globally by rolling out the Belle software for the existing Nokia range of smartphones such as N8, E7, X7, C6-01, C7, Oro, E6, and Nokia 500 in early 2012. With that, millions of consumers around the world will get a totally fresh experience on their Symbian smartphone."
Back in September, Nokia had launched three new Symbian Belle smartphones in India with NFC technology, the Nokia 600, Nokia 700, and Nokia 701.
