Core Values: The silicon behind Android
Core Values is our new monthly column from Anand Shimpi, Editor-in-chief of AnandTech. With over a decade of experience poring over the latest in chip developments, he's here to explain how things work and why our tech is the way it is. Remember this chart? It's interesting for a number of reasons, but I want to highlight that all present day Android phones use virtually the same Qualcomm application processor, all based on a sluggish 528MHz ARM11 core. Blech. I've got nothing against Qualcomm, but a big reason most Android phones feel slow is because they're running on slow hardware. The ARM11 core was first announced in 2003. It's old and creaky, and it's used so frequently because it's cheap. But the basic rules of chip design mean that things are about to change fast.
Nokia N900 undergoes extensive preview, N97 found sobbing in a corner
Our amateur sleuthing skills tell us there might be a tiny bit of excitement about this N900 device. With the Maemo 5 environment already measured up, it's the turn of the hardware to get exhaustively previewed. The My Symbian team took a look at a prototype unit and were immediately impressed by the 800 x 480 display and relatively compact dimensions for such a loaded phone. The resistive touchscreen was on par with the N97, though it picked up scratches too easily for their liking ( a screen protector is recommended), while the keyboard was deemed small but still a major improvement over the N97's. Internals rated well, with the 600MHz Cortex-A8 CPU and "superb" video recording grabbing plaudits. Perplexingly, there was only 256MB allocated to application installs (see image after the break), which can be altered by those with Linux knowhow, but this may draw plenty of ire from mainstream, app-hungry consumers, considering the device is capable of holding 48GB of total memory. On the outside, the camera cover was found to scratch the case around the lens (but not the lens itself like on some N97 units) while sliding, and removing the stylus from its slot revealed some bare electronics, both of which rather undermined the overall feel of a well-built device. They did find connectivity on the device a pretty dreamy and trouble-free affair, but we're still only scratching the surface here -- hit up the read link for the whole enchilada. [Via MobileTechWorld]Update: Nokia has expressly stated that the retail phones will come with repartitioned memory, which will provide "plenty" of space for app installations and obviate the storage issue noted above.

Samsung R&D goes bananas for mobile, intros 1GHz processor, 5 megapixel camera-on-a-chip, much more
In a Samsung-esque introduction, Samsung has unveiled a crazy stack of tech for mobile devices, most of it aimed at improving performance in high-end devices while reducing power consumption -- an initiative we can always get behind. Among the introductions are a pair of 1GHz ARM CORTEX A8 processors, one for phones and one for larger mobile devices, the former of which can be paired with Samsung's new 1Gb OneDRAM solution, and both of which can churn through 3D graphics while keeping power usage to a minimum. Other highlights include a 5 megapixel CMOS system on a chip camera, which can process 1080p at 30 fps, a 512Mb PRAM chip newly in production, and a mobile display driver with integrated capacitive touchscreen support. With samples of the processors out in December, and the camera trickling into the market Q1 of next year, we probably have a ways to wait for devices based on all this tech -- but boy are we prepped for it.

Samsung announces world's fastest Cortex A8 core, iPhone 3GS frowns a little
Some of the most advanced mobile devices on the market today are built around cores based on ARM's Cortex A8 architecture, including a couple you may be familiar with: the Palm Pre and the iPhone 3GS. The 3GS, for example, runs a Samsung S5PC100 system-on-chip clipping along at a healthy 600MHz, enough to make it noticeably snappier than the 3G it replaces -- but time marches relentlessly forward, as always, and that S5PC100 is suddenly starting to look a little long in the tooth with today's news. Sammy has partnered up with silicon design firm Intrinsity to develop what it's billing as the world's fastest Cortex A8 core, a 1GHz unit codenamed "Hummingbird" that's based on 45nm manufacturing techniques and can deliver peak performance at a single volt with power consumption characteristics favorable for mobile use. Translation: this thing should be nipping at the heels of Snapdragon once Samsung finishes up work turning this core into a system-on-chip that can be sourced by manufacturers, and it should do so without causing batteries to beg for mercy. Unfortunately, there's no word just yet on exactly when we'll see phones running this setup in the market, so Pre, 3GS, you're safe for now -- but the clock's ticking.
Freescale netbook and Android-powered smartbook debut
We knew good and well that Freescale wouldn't let Qualcomm go and have all the fun with these newfangled smartbooks, and already we're seeing a few new devices powered by Freescale-branded semiconductors. In the video posted just after the break, the company's own Steve Sperle sat down to talk about a new Pegatron netbook (which handles 720p video playback with ease) as well as an Inventec "smartbook" which is just marginally larger than your average smartphone. In fact, we're rather impressed with the layout: a larger-than-average 4-inch display, a slideout QWERTY keyboard and Google's Android OS. Unfortunately, Mr. Sperle would only stick close to the "later this year" launch time frame that we'd already heard about, but so long as these smartbooks end up looking like overpowered smartphones, you can certainly consider our interest piqued.
ARM-based netbooks primed to invade Computex?
Steppin' out in the world, are we ARM? Shortly after hearing that OLPC was eying the brand for processors in the XO-2, Digitimes is now reporting that ARM-based platform makers including Qualcomm and Freescale are looking to unveil netbooks at this year's Computex trade show in Taipei. Granted, none of this has been confirmed just yet, but we're hearing that a model with Freescale's i.MX51 CPU (the ARM Cortex A8) and a version with Qualcomm's Snapdragon CPU (to be manufactured by Wistron) will be on hand. Not shockingly, in the same breath we're told that NVIDIA Tegra-based systems will appear "at a later time." So, is Computex the show where Intel finally takes a little heat in the netbook market? And no, VIA didn't (and doesn't) count.
Freescale's i.MX515 netbook chip now supports Android and Xandros
When we first laid eyes on Freescale's five-core i.MX515 processor this January, we hoped it was all it claimed to be -- promising an extremely cool machine with a low power budget and a price point that'll take your next netbook down near the fabled $199 range. So far, so good: the Pegatron machines we peeped at CES fit the bill quite nicely, and now ZD Net is reporting that the Cortex-A8-based chip supports the HyperSpace instant-on OS, specially optimized 3G HSDA data modules from Option and Wavecom, and both Android and Xandros. Of course, none of this will be of any help to you if you're married to Windows -- but then again, even if you are we wouldn't really blame you for wanting a little Linux on the side. Especially if it comes in a sweet package like this.
Pandora finally (finally!) gets a ship date and price
Be still our hearts! After months upon months (upon months) of waiting, the tight-knit team behind the ultra-potent Pandora gaming handheld has finally divulged the information we've been clamoring for: the ARM Cortex A8-powered device will begin shipping before Christmas 2008 for £199.99 in the UK. The first batch will consist of 3,000 units, and the team is hoping that all of those will be sold out before the first one leaves the dock. There's no word on how costly it'll be for Americans, though we're crossing our fingers that it'll sell for a few bucks less than the $360 we find when simply converting pounds to dollars. [Thanks, Andri]
