Kal-El Tegra SoC to use 5 cores

Recent news from NVIDIA has unveiled some interesting new technical details about the upcoming Kal-El ARM-based Tegra SoC.  While we have known for some time that this chip would include a quad-core processor and would likely be the first ARM-based quad-core part on the market, NVIDIA's Matt Wuebbling spilled the beans on a new technology called "Variable SMP" (vSMP) and a fifth core on the die.

This patented technology allows the upcoming Tegra processor to address a couple of key issues that affect smartphones and tablets: standby power consumption and manufacturing process deviations.  Even though all five of the cores on Kal-El are going to be based on the ARM Cortex A9 design they will have very different power characteristics due to variations in the TSMC 40nm process technology that builds them.  Typical of most foundries and process technologies, TSMC has both a "high performance" and a "low power" derivative of the 40nm technology usually aimed at different projects.  The higher performing variation will run at faster clock speeds but will also have more transistor leakages thus increasing overall power consumption.  The low power option does just the opposite: lowers the frequency ceiling while using less power at idle and usage states.

NVIDIA's answer to this dilemma is to have both - a single A9 core built on the low power transistors and quad A9s built on the higher performing transistors.  The result is the diagram you saw at the top of this story with a quad-core SoC with a single ARM-based "companion."  NVIDIA is calling this strategy Variable Symmetric Multiprocessing and using some integrated hardware tricks it is able to switch between operating on the lower power core OR one to four of the higher power cores.  The low power process will support operating frequencies up to only 500 MHz while the high speed process transistors will be able to hit well above 1-1.2 GHz.

Everyone's favourite Transformer

You had better not think this refers to Bumblebee.  The real Transformer you shold be be thinking about comes from ASUS, the ARM based Tegra 250 T20 powered Eee Pad Transformer.  More than a tablet thanks to the special dock, which turns the tablet into a netbook with a full keyboard, this device has received a lot of positive press.  TechSpot had a chance to use one, powered by Honeycomb 3.2, and they agree with the other reviewers; considered as a simple tablet it isn't quite as good as the iPad but the real selling point of the Transformer is the keybaord.  Read on.

"The Eee Pad Transformer goes beyond what most tablets are capable of by doubling as a Honeycomb-based netbook. Based on that premise and an attractive price since launch, it quickly became one of the most attractive Android tablets around.

If you are willing to look past the widely dominant iPad, we are paying another visit to Android Honeycomb (currently on version 3.2) along with one of the most popular and well regarded tablets under its umbrella."

Add Ubuntu to your HP Touchpad

If you are like Scott and think that the cut rate price of the HP Touchpad is just too good to resist you might want to put on an OS that you know will still be around in a year or two.  Techware Labs have written a guide on how you can install Ubuntu on your touchpad in addition to WebOS so you don't have to wipe out the Touchpad's original functionality.  Make sure you back everything up however as you will be spliting the storage media into two partitions, one for WebOS and one for Ubuntu.   Happy modding.

IDF 2011: ASUS UX21 Ultrabook Still Sexy, I Still Want It

Yes, I realize the ASUS UX21 was first shown at Computex in June, but this was my first chance to get my hands on it and I have to say after using it for just a few minutes and comparing it to the aging Lenovo X201 that I am typing this on, I am in love with the form factor.

I don't have anything else to report yet - no performance metrics, no real-world testing, but I couldn't pass posting these few pictures of it.  Enjoy!

Not an Ultrabook but it could be, Samsung's Series 9

Subject: Mobile | September 6, 2011 - 04:59 PM |
Tagged: Samsung, Series 9, ultraportable

If you are in the market for an ultraportable Intel notebook, instead of waiting to see what becomes of the Ultrabook you could consider the Samsung Series 9.  A 13" notebook powered by a Core i5-2537M with 8GB of DDR3-1333 and a 256GB Samsung SSD pretty much matches anything that is on the market.  At $1300 it is a bit expensive but for a 12.9" x 8.9" x 0.64" notebook with that much power you have to expect a steep entry fee.  The Tech Report were impressed overall with some negative points from the keyboard's quality and the battery life which was not as long as they had hoped, you can't expect much more than four hours from the notebook.

"This 13" notebook has much in common with Apple's MacBook Air—an almost impossibly slim chassis, a very light weight, a low-voltage Sandy Bridge processor, and solid-state storage. Did Samsung hit a home run with this laptop, and is it worth the money?"

Introduction and Design

transformer3.jpg

Tablets may be the darling of the tech industry, but they’ve also received their fair share of criticism as well. One of the most consistent barbs throw towards them is the tablet’s inability to serve as a competent platform for content creature. While it’s technically possible to write a document or edit an image on a tablet, it’s certainly not enjoyable.

Part of the problem is the lack of a keyboard and mouse. Touchscreens are beautiful and intuitive, but they’re not precise. While third-party cases and docks have tried to solve this issue, they’re often both clunky and expensive.

It’s little surprise that a tablet designed specifically to work in conjunction with a keyboard dock has hit the market, but it is surprising that the first such device comes from ASUS, a company with relatively little experience building mobile products. The Eee Pad Transformer is already the second-best selling tablet on the market (after the iPad, of course) and reports indicate sales are constrained by supply rather than demand. What is it that has made the Transformer a quick success?

Acer Unveils Super Thin Aspire S3 Ultrabook at IFA in Berlin

Subject: Mobile | September 3, 2011 - 08:03 AM |
Tagged: ultrabook, ssd, Intel, acer

Hot on the heels of the Toshiba and Lenovo ultrabook announcements comes a new ultrabook from Acer. Engadget recently got their hands on the new Acer Aspire S3 ultrabook at the IFA (Internationale Funkausstellung Berlin) technology showcase in Berlin. The 13.3” computer carries some impressive specifications, including a 7 hour long battery life, metal chassis, and the latest Intel processors.

img7688.jpg

To be more specific, the Acer computer is a 13.3” ultrabook composed of a magnesium alloy chassis measuring 13mm thick. Inside the metal frame lies an ultra low voltage Core i3, i5, or i7 Sandy Bridge processor, DDR3 RAM, and an interesting storage solution made of a 20GB SSD and 320GB mechanical hard drive combination. Acer is promising a 7 hour battery life, and a 1.5 second resume from sleep time. Further, the ultrabook features a glossy 1366 x 768 resolution display, and a chicklet keyboard whose keys Engadget notes feels like plastic.

While their is no word on US pricing, Acer has released the European starting price at €799. Compromises have been made to reach the price point (mainly in the keyboard); however, if the specifications and design hold up it looks to be a solid competitor in the ultrabook market.  More photos as well as a video tour of the ultrabook can be found here.

Toshiba Unveils Portege Z830 Ultrabook Series

Tagged: z830, ultrabook, toshiba, sandy bridge, portege, Intel

There has been quite the buzz over ultrabooks for the past few weeks, and it seems as though Toshiba is ready to grab their slice of the news pie (actually, can we have cake?) with the announcement of their Portege Z830 series of, you guessed it, ultrabooks.

6083662507_e888f2cdf6_o.jpg

Powered by Intel Sandy Bridge processors, the ultra (slim) book is housed in a magnesium alloy chassis measuring 15.9mm (0.63 inches) thick. Slated to be 20% lighter and 40% thinner than their previous ultraportable Portege R830 series, the company has reinforced the chassis with a honeycomb ribbing (I’m sure Josh is making a joke out of that right now) and some new internal shock dampening structures.  The company stated that the Z830 would weigh less than 2.5 lbs, though the number may vary depending on the specific configuration.  Because the notebook is so thin, they needed to go metal for the chassis to prevent serious warping and bending of the computer (and is coincidentally one of the items that caused manufacturers to complain about the sub-$1,000 requirement). Other chassis features include a full size LED backlit and spill resistant keyboard.

6084203814_fa55005edd_b.jpg

Other hardware details about the computer are scarce in that Toshiba has not released much. The ultrabook will contain a 128 GB solid state drive and DDR3 memory. From photos of the ultrabook, the computer supports (likely Gigabit) Ethernet, USB, and HDMI ports. Stereo speakers by Waves Audio, Toshiba’s High Speed Start and USB Sleep and Charge technologies are also featured.

The Protege Z830 ultrabook series will be available in November 2011, and will carry a MSRP of less than $1,000 USD. Stay tuned to PC Perspective for more ultrabook coverage.
