AMD Shows Off New Radeon Chips
AMD has now officially updated its HD 7000M lineup of mobile GPUs with HD 7700M, HD 7800M and HD 7900M GPUs that are all based on AMD’s 28nm GCN architecture. The first in line that should show up in notebooks is the flagship HD 7970M GPU.
As noted, the entire lineup is based on AMD’s 28nm GCN architecture, but as always, the naming scheme of the AMD mobile parts has nothing to do with the desktop ones. The HD 7900M, codename Wimbledon, is actually based on 28nm Pitcairn destkop GPU that features 1280 stream processors, 80 texture units, 32 ROPs and up to 2GB of GDDR5 memory paired up with a 256-bit memory interface.
The HD 7800M series, codename Heathrow and the Radeon HD 7700M series, codename Chelsea, are both based on Cape Verde desktop GPU but with a slight twist. While Heathrow, HD 7800M series features fully enabled Cape Verde GPU with 640 stream processors, 40 texture units and 16 ROPs, the Chelsea HD 7700M series is based on a “crippled” Cape Verde core with 512 stream processors and 32 texture units. Both the HD 7800M series and the HD 7700M series will feature up to 2GB of GDDR5 memory paired up with a 128-bit memory interface. Of course, we expect at least two SKUs for both HD 7700M and HD 7800M series.
AMD also decided to ditch the PCI-Express 3.0 support on the HD 7700M series mainly as this one is aimed at lower-performance platforms that are all about power saving, and performance gain was simply too low.
For now, AMD has only shed precise details regarding the HD 7970M GPU that is based on the fully enabled Pitcairn GPU with 1280 stream processors that will end up clocked at 850MHz for the GPU and 4.8GHz for 2GB of GDDR5 memory paired up with a 256-bit memory interface.
As you can notice, the HD 7970M has lower GPU clocks than its HD 7870 desktop counterpart, but AMD also decided to keep the memory at the same level resulting in 153.6GB/s of memory bandwidth. According to AMD slides, HD 7970M should end up to be anywhere between 30 and 60% faster than HD 6990M and anywhere between 16 and 76 percent when compared to Nvidia current high-end GTX 675M GPU.

Comments Off on Apple Faces Another Lawsuit
Apple devices using touch technology infringe on a patent owned by the Pennsylvanian company FlatWorld Interactives, the company stated in court documents filed on last Friday. FlatWorld asked for a permanent injunction that Apple stop infringing, and for sufficient compensation for the infringements, the company’s attorneys said.
The Pennsylvanian designer of touchscreen systems for use in museum displays alleged that Apple knowingly infringed on its patent, according to documents filed with the U.S. District Court for the Northern District of California said. The infringing products are said to include the iPhone, iPad, iPod Touch, MacBook Pro, MacBook Air, Magic Mouse and Magic Trackpad.
FlatWorld said Apple’s infringement has been on a massive scale and has caused it irreparable harm. The company demanded a permanent injunction enjoining Apple from continued infringement plus an unspecified amount of damages to compensate for Apple’s infringement. The company is seeking a jury trial.
FlatWorld was founded in January 2007 by Slavko Milekic, a professor in cognitive science and digital design at the University of the Arts in Pennsylvania, in order to commercialize his touch screen patent, the filing said.
Milekic filed a provisional patent application on August 28, 1997, claiming priority from that date in his definitive patent application, according to the court documents. He applied for his patent on June 12, 1998 and was granted it as U.S. patent 6,920,619 on July 19 2005, according to the U.S. Patent and Trademark Office.
Rackspace Goes Openstack
Rackspace has finally deployed an Openstack based cloud, playing down claims that it benefits the most from the alliance.
Rackspace is one of the leaders of the Openstack alliance, an open source cloud initiative that aims to break Amazon’s stranglehold on the industry by offering open application programmable interfaces (APIs). Until now Openstack has largely been all talk, but Rackspace has deployed a production Openstack cloud that the firm claims will help it sell Openstack to the enterprise.
Fabio Torlini, VP of cloud at Rackspace said the firm has been “going flat out to make the code production ready”. Torlini said Rackspace’s decision to deploy an Openstack based cloud could be a tipping point in deployment. “It’s going to be the catalyst for many other companies deploying Openstack,” said Torlini.
Rackspace has been the largest contributor to Openstack and the fact that it has the first major Openstack deployment support claims that Rackspace is getting the most out of Openstack.
However Torlini said, “For us, we’re able to be the first one to launch a large scale Openstack compute platform because, yes, we are one of the main providers of the original code and we are a founder of Openstack, so we have tried to develop Openstack as a neutral foundation and it is a foundation to provide a service to all its members. But we’re lucky enough to be one of the founder members, to be able to drive it, and get there [deployment] first.”
Torlini defended Rackspace’s role in the Openstack alliance, claiming the strong leadership shown by the firm is good for the community. Torlini said, “Openstack is beneficial to the product itself but that’s the whole point. The whole idea of many more providers going onto Openstack helping develop the Openstack cloud, helping advance the actual products and code is the whole point of Openstack. On the counter side of that argument is if it’s beneficial for us it is just as beneficial for any other member of Openstack because they have access to the same code and they are able to provide.”
Torlini admitted that Openstack and the community is an advantage for the firm but claimed it wasn’t possible for Rackspace to dominate. “You have companies in Openstack that are far larger than Rackspace enabled to put much more resources into Openstack as well, it’s impossible for us to dominate Openstack – it’s an independent foundation. Is it advantageous from a product perspective? I should damn well hope so,” said Torlini.
More Trojan Malware Found On Macs
Following the outbreak of the Flashback Mac Trojan, security researchers have identified two more cases of Mac OS X malware. The good news is most Mac owners have little reason to worry about them.
Both cases are variants on the same Trojan, called SabPub, Kaspersky Lab Expert Costin Raiu wrote on Securelist.
The first variant is known as Backdoor.OSX.SabPub.a. Like Flashback, this new threat was likely spread through Java exploits on Websites, and allows for remote control of affected systems. It was created roughly one month ago.
Fortunately, this malware isn’t a threat to most users for a few reasons: It may have only been used in targeted attacks, Raiu wrote, with links to malicious Websites sent via e-mail, and the domain used to fetch instructions for infected Macs has since been shut down.
Furthermore, Apple’s security update for Flashback helps render future Java-based attacks harmless. In addition to removing the Flashback malware, the update automatically deactivates the Java browser plug-in and Java Web Start if they remain unused for 35 days. Users must then manually re-enable Java when they encounter applets on a Web page or a Web Start application.
The second SabPub variant is old-school compared to its sibling. Instead of attacking through malicious Websites, it uses infected Microsoft Word documents as vector, distributed by e-mail.
Is Samsung Pursuing The Server Market?
Comments Off on Is Samsung Pursuing The Server Market?
It is certain that Korean electronics giant Samsung will soon be entering the server chip market.
Reports are coming in that the company has been picking up key server personnel from Intel and AMD. Samsung has been focused on developing ARM chips and stayed clear of the x86 architecture used by Intel and AMD.
But the companies latest hires seem to indicate that might change.
Samsung’s latest recruits include veterans of the chip business like Jim Mergard, Frank Helms, who is a Fusion APU architect, Brad Burgess who designed the Bobcat APU and Patrick Patla (VP of AMD’s server business). Patla was behind the success of the Opteron chip set and has done well using the x86-server system.
Intel Appears To Be Dedicated To Tizen
Comments Off on Intel Appears To Be Dedicated To Tizen
As we know Intel is not a total Windows 8 and Android shop. Although MeeGo was abandoned by Nokia in favor of huge investment from Microsoft, but Intel will continue to develop MeeGo and it will also add Tizen to its OS effort.
Tizen is a free open source mobile operating system based on Linux and backed up by Linux foundation. Tizen is planned to work on Atom N2800 and N2600 processors or simply said Cedar Trail platform and it was supposed to be out of Beta by end of Q1 2012. If all goes according to schedule it will reach its gold status by mid of Q2 2012. At some point it will also get an application store too, but release schedule is yet to be set in stone.
Intel believes that Tizen combines the communities and best technologies under one unified environment. MeeGo is supposed to have Strong developer community and LiMo should bring broad service provider support to this marriage. They will have strong support for HTML 5 and WAC (wholesale application community).
Tizen is supposed to work on ARM as well as on x86 and we can expect the first devices, or at least prototypes, to show up by the end of the year. Once it gets out it should cover mobile phones, tablets, netbooks, smart TVs and in-vehicle entertainment systems.

Comments Off on Are Medical Implants Vulnerable To Hackers?
Security experts have warned that many medical implants are vulnerable to cyber attacks that could endanger their users’ lives. While an increasing number of patients are being fitted with devices such as pacemakers and insulin pumps to manage chronic conditions apparently the inventors did not think anyone would be evil enough to try and hack them.
For some reason they installed unprotected wireless links so that they could be updated easily. Therefore this means that hackers could gain remote control of such implants because they rely on unprotected wireless links to update them. After gaining access to the device, a cyber criminal could then switch it off or tell it to deliver a dangerous dose of medicine to the patient.
Is E-Commerce Next For Facebook?

Comments Off on Is E-Commerce Next For Facebook?
A group of e-commerce start-ups, backed by some of the tech world’s most respected financiers, are hoping that Facebook Inc will become an e-commerce powerhouse to rival Amazon.com Inc and eBay Inc.
As the world’s largest social network moves toward a $5 billion initial public offering, it will come under more pressure from Wall Street to generate new sources of profit growth and reduce its reliance on advertising, which accounted for 85 percent of its 2011 revenue.
Some entrepreneurs and investors increasingly think “f-commerce” – meaning e-commerce on Facebook – is the answer. Start-ups such as BeachMint, Yardsellr, Oodle and Fab.com are coming up with novel ways to persuade Facebook users to not just connect with friends on the social network, but to shop as well.
Backed by tens of millions of dollars from venture capital firms like Accel Partners and Andreessen Horowitz, and other big investors like Goldman Sachs, these start-ups are pushing out shopping apps, hosting online garage sales and testing out new business models on Facebook.
“E-commerce is a huge category with very strong tailwinds and it’s a natural move for Facebook,” said Sam Schwerin of Millennium Technology Value Partners, which owns Facebook shares and has a stake in BeachMint.
Amazon revolutionized online shopping by crunching lots of customer and purchase data to come up with relevant, personalized recommendations. In the same vein, Facebook’s combination of data, analytics and payment technology could fuel the next generation of e-commerce, Schwerin said.
Samsung Making Ultra MicroSD Card
Samsung Electronics has started mass producing a microSD card that uses an Ultra High Speed-1 (UHS-1) interface to greatly improve data transfer speeds, the company said in an announcement on Wednesday.
The microSD HC card stores up to 16GB and has a maximum sequential read speed of 80MBps (megabytes per second), according to internal tests conducted by Samsung. That is more than four times the read speed of today’s advanced microSD cards, which have speeds up to 21MBps, Samsung said.
What real-world speeds that will translate into remains to be seen. The card will be a good fit for LTE smartphones and tablets, according to Samsung.
AMD’s Trinity To Have Fewer Cores
AMD’s soon to launch A10 5800K is a 100W quad-core Trinity 32nm CPU with 3.8 GHz base clock and 4.2GHz maximal clock possible with AMD turbo core dynamic overclocking technology.
The A10 5800K has 4MB of L2 cache, supports DDR3 1866, dual graphics configurations as well as AMD’s new FM2 socket. The fun part is new HD 7660D GPU that works at 800MHz and comes with 384 shader units. The current APU market leader A8 3870K that works at 3GHz has HD 6550 graphics with 400 cores running at 600MHz.
AMD claims that new Radeon cores from Trinity CPU including A10 5800K are more efficient and this is the main reason why you have fewer cores that can deliver superior performance. The other reason is that with 800MHz core clock they can probably process more data, meaning that HD 7660D of A10 5800K should end up quite a bit faster than the Llano A8 3870K.
All these Radeon cores are a key feature of the Vision Engine that accelerates GPU enabled applications. AMD also tells the world that Trinity is DirectX 11 compatible, supports Direct compute and the new A series of processors, including the A10 5800K all the way to dual-core A4 5300, should not have any issues playing Blu-ray 3D. The GPU part of Trinity supports AMD V, UVD3 as well as Open CL acceleration.
