Anandtech: Apple iPhone 5 features 1GB of RAM, A6 is a custom SoC

Unsurprisingly, Apple left us in the dark regarding some specifics of the iPhone 5 upon its release. Thankfully, the good folks over at Anandtech have done a bit of digging into those numbers you see bordering Apple's Apple A6 SoC, definitively figuring out that Cupertino's latest phone packs in a total 1GB of Samsung-sourced memory. The site clocks the DRAM inside at 1,066Mhz, noting that it's comprised of "two 512MB dies in a dual-channel LPDDR2 package with 32 bits per channel." Further, Anandtech lists the the speed of the iPhone 5's memory at 8,528MB/sec -- an ample 33 percent boost over the 6,400MB/sec rating for the RAM in the iPhone 4S, but well below the 12,800 MB/sec needed to drive the new iPad's bandwidth-hungry screen resolution.

Beyond that, the site believes that the A6 is Apple's first truly in-house creation, as it's using math units too new to be found in a ARM Cortex-A9 architecture (like the A5 or A5X) but reportedly isn't a match for the soon-to-be-released Cortex-A15. If true, the implication is significant -- it suggests Apple is taking the more aggressive path of a chip designer like Qualcomm and custom-tailoring large parts of its processor designs to get the speed it wants on a more exacting schedule. That's a quick summation of the details; hit up the source links below if you want the explanation in full geek speak.

IHS iSuppli: PCs no longer command biggest share of DRAM market

Times change, this is an indisputable truth. But nothing reminds us of this fact as well as a landmark statistic. If there was ever any doubt about the shift towards of mobile computing, then let this be it: personal computers no longer account for the majority of demand for DRAM chips. With 49 percent of all new memory still headed for PCs, it's hardly time to book the hearse for desk- and laptops just yet, but the statistic from IHS iSuppli remind us of the increasing market share that mobiles and tablets are taking. In fact, even though total DRAM shipments for PCs continues to rise, it's estimated that the total share will slip another 6 percent, to 42.8, between Q2 this year and the end of 2013. Of course, this is good news if you have a vested interest in both, not so good if you don't.

Intel claims Clover Trail-based Atom won't properly run Linux, points us to Windows 8 instead

Source: http://www.engadget.com/2012/09/14/intel-claims-clover-trail-based-atom-wont-properly-run-linux/

There's potentially bad news ahead if you're hoping to wipe the drive on that future HP Envy X2 and load Ubuntu -- Intel reportedly claimed at IDF that Clover Trail-based Atom processors "cannot" handle Linux properly. As outlined in The Inquirer's account of events, the issue is more a matter of optimization than an outright block: Linux doesn't yet know how to cope all of Clover Trail's power state changes at the kernel level, which would put any penguin-powered PC at a disadvantage. Intel would really, really prefer that you run Windows 8, as the new Atom and Microsoft's OS are tuned to work hand-in-hand. Linux might catch up, but the Windows-only emphasis is a sharp break from Intel's tendency to shower love on open-source OS projects across the board, including ongoing work like Intel-native Android builds or Tizen.

NVIDIA GeForce GTX 650 and 660 review roundup: hitting the sweet spot, sometimes

Source: http://www.engadget.com/2012/09/14/nvidia-geforce-gtx-650-and-660-review-roundup/

If you're building or upgrading a budget gaming rig, it'll be hard to ignore the GeForce GTX 650 and 660. Whether or not NVIDIA's new chipsets are worth the glance is another matter, and early reviews suggest that a sale depends on just which market you're in. The GTX 660, by far the darling of the review crowd, competes solidly against the Radeon HD 7850 by outrunning AMD's hardware in most situations while undercutting on the official price. Only a few have taken a look at the lower-end GTX 650, but it's not as much of a clear-cut purchasing decision -- the entry-level video often slots in between the performance of the Radeon HD 7750 and 7770 without the price edge of its bigger brother. Either card is much better value for the money than the GT 640, however, and looks to be a meaningful upgrade if you're trading up from equivalent prior-generation gear.

Google plays privacy catch-up, adds Do Not Track option to Chrome

Source: http://www.engadget.com/2012/09/14/google-brings-do-not-track-to-chrome/

Google's had one foot in the web privacy door for a while, offering Chrome users the Keep My Opt-Outs extension in its browser's Web Store since 2011. Still, Firefox, Internet Explorer and Safari already offer a Do Not Track option directly in their browser settings. Mountain View is now working to close that gap by bringing that same privacy configuration to Chrome. Do Not Track will let users opt out of tracking cookies and targeted advertising (from ad networks that comply with the standard, that is), and is currently live on Chrome's developer channel. The option will reportedly be baked into the stable version of the browser by the end of the year.
