We can easily say NVIDIA’s press conference is among the most eventful for Android fans, at CES 2013. We have a new handheld console, Grid Cloud Gaming and Tegra 4 coming. Tegra 4 is quite the beast, but just how powerful can it be? Well, we have found out it can output 4K video to a 4K TV.
In our hands-on video, you can see a demo of NVIDIA’s Tegra 4 developer tablet runnin a 4K sample of After Earth’s trailer on a stunning 84-inch (3840 x 2160) television. Many tablets struggle to output even 1080p video. And with no lag or latency, we know this processor definitely has the guts to take on any task.
It’s hard to give justice to such resolutions through video, but you can definitely notice how good it performs. You will simply have to trust us on the resolution quality, though – it is stunning! Hopefully one day we can all afford a 4K TV and enjoy this.
awesome…
Movie looks like it will be fun to see. Im done with movie collections though. I wont be buying any more blu ray or 4k movies when they come out. No more physical media!
Hope you’ve got unlimited home internet… just because if a 1080p movie can be a few GB’s, I hate to imagine what 4 times the pixels would do to your bill.
Who doesn’t have unlimited internet? It’s 2013, bandwith would be the problem here, not money.
Most ISP’s have data caps (at least in the US), and those that don’t are heading that direction.
Canada my friend. Canada.
The main providers provide ridiculous caps on bandwidth here.
Top end packages with 200GB caps, etc.
You can get fast internet, just don’t use it lol.
120g/month,Montréal. Had unlimited some years ago, but they removed it
wtf, u have an limited home internet service!?!? Sucks to be you!!
Yes, I do have unlimited. 50GB connection. I can maintain roughly 2-3Mbps through wireless. Plus, this is what the pirate bay is for
holy moly…
exept it looks like a mirror
going to have to Google this 4k nonsense. 4k of what?
4000 unicorns puking tiny pixel rainbows.
This video is probably optimized to run on it. Anyone could do this for CES. Heck, the PowerVR SGX540 can do 1080p supposedly, but it really can’t unless it is recorded from a phone with a 1080p camera, or the video is meant for it, like something crappy on youtube. In real world application it can’t even handle 720p. The Adreno 225 can just do 720p. not 1080p at all. I bet the 320 can do 1080p, but I’d be amazed if the Tegra 4 could actually do 4k properly. I imagine it’ll only do 1080p for all practical intents and purposes for a long time, and no one will care because 4k tv’s are just becoming the new big thing now and won’t be available at an affordable price for a few years at least.
A friendly hint. Video decoding is not done in the GPU.
Basically all you write above is therefore incorrect.
In fact most modern smartphones decode 1080p video without any problem. Only low end smartphones will have problems.
However 4k is another matter. It will be interesting to see how well this actually works and also when a 4k TV becomes affordable.
Really? What does the hardware decode option on almost all video players use then? Last I checked
software decode uses software so the cpu can decode Hardware decode uses the GPU to handle decoding. Most every video I play is decoded by the GPU. A dual core arm cortex a9 can’t even handle 720p video and would by no means be low end. You clearly don’t know what you’re talking about.
decoding uses
Well the hardware decode option uses the special purpose decoding hw ofcourse.
Lets take qualcomm as an example: http://en.wikipedia.org/wiki/Qualcomm_Hexagon
Broadcom: http://en.wikipedia.org/wiki/VideoCore
Tegra 3, see page 7: http://www.nvidia.com/content/PDF/tegra_white_papers/tegra-whitepaper-0911b.pdf
So they use DSPs, not GPUs.
But is it clear?
