Don’t Buy a Dual-Core Tablet Until You See This Video
By Kevin C. Tofel May. 29, 2011, 8:00pm PT 5 Comments
The first dual-core Android tablets only arrived in February, but Nvidia is
already showing off an improved quad-core chip that’s expected to power
tablets by August. The system-on-a-chip, codenamed “Kal-El,” has four
computer cores and a dozen graphics processors that will offer a huge
performance boost in mobile devices. Nvidia announced the chip in February,
with support for 1440p video playback, which is higher than most HDTV sets.
To get an idea of what to expect from Nvidia’s new mobile chip, the company
shared a video demonstration with me last week, which is now available for
public viewing. Take a peek at the game demonstration that focuses on
dynamic lighting and detailed physics on an Android Honeycomb tablet at 1280
×800 resolution.
The video prowess of the upcoming chip is impressive; you can get a real
feel for it when the demonstration drops down to using just two of the four
processing cores. Kal-El should bring faster device response times, vastly
improved graphics, quicker camera applications and more. But perhaps the
chip is too impressive when it comes to product timing.
If the first dual-core tablets launched in February and slates using this
new quad-core chip could be available by August, that means the very young
Google Honeycomb tablet market is essentially running through a product
cycle in six short months. Improved performance is always welcome, but I
wonder if the growing number of consumers who are shopping for a tablet will
simply hold off for a few more months.
The same can be said of smartphones because Nvidia expects handsets to run
on Kal-El chips by this holiday season. I’m generally an early adopter but
I haven’t yet moved to a dual-core handset. I’m in the process of choosing
the device that will replace my Nexus One and this development makes the
decision a little harder: Do I wait or just pull the trigger now, knowing
that there’s a good chance of a big hardware boost by the end of the year?
Regardless of the increasing technology cycle and what that will do to
consumer purchase decisions, the advancements shown in Kal-El are a positive
development for mobile technology. This year might be known as the year of
dual-core chips, but if Nvidia has anything to say about it — not to
mention competitors such as Qualcomm, Texas Instruments, Marvell and others
who are working on their own faster chips — 2012 is looking to be the year
of quad-core devices. |
