Nvidia Tegra K1 runs full-on Unreal Engine 4 on a tablet (video demonstration)

The Nvidia Tegra K1 is a big deal first and foremost for mobile gaming. The K1 features an impressive 192-core Kepler GPU, a desktop-class graphics chip, and to fully show its potential Nvidia teamed up with Epic Games for a demonstration. Gamers will be excited to see the full-on Unreal Engine 4, the graphical engine driving some of the latest PlayStation 4 games, running on a reference design Nvidia tablet.

How powerful is the Tegra K1 then? “You can take absolutely anything that runs on PC or a high-end console and run it on a Tegra hardware. From here onward I think we’re going to see performance and feature gap between mobile and PC and high-end gaming continue to narrow to the point where the differences between the platforms really blur,” Tim Sweeney, Epic Games, Founder and CEO, explained.

This is not the first impressive demo of Kepler we’re saying, but it’s a very convincing one, with a real-world game engine. Nvidia has taken care of gamers with one more software feature called G-Sync. G-Sync aims to basically be an improved V-Sync that avoids the occasional stuttering and screen tearing that forces many professional gamers to actually turn off V-Sync. Simply put, G-Sync synchronizes the 60 hertz output of most monitors with the varying framerate of games (intense fights can lead to low single-digit frame-rates while in other situations games run at more than 100 fps), minimizing lag along the way. This is a feature, though, that seems mostly targeted at non-mobile form factors.

What should really give you a good idea of the Tegra K1, however, is the actual demo, so with no further ado, watch it right below.

This is what we call making no noise and then Boom...

I think Nvidia forget that mobile is about Performance per watt not peak performance ... yes the GPU is amazing and its 2.5 times more powerfull than A7 (Power VR 6430 quadcore) in its peak.. but A7 is a working SoC with 12 hour web and video and 7+ hour for 3D games.. how about some battery numbers or additional features like qualcomm ones.. qualcomm had shown many cool features for its Snapdragon lineup .. (ultrasonic pen, image processing, video encoding ... etc ) who cares about Gpu peak performance anymore? S800 wasn't just about Adreno 330 either.. it was about huge pile of features (fast charging, LTE-A , always on voice, image processing, 1080p 60fps 720p 120fps .. etc) plus performance per watt advantage over other flagships like octa or Tegra 4 ..

Nvidia actually dropped some ballpark numbers saying the Tegra K1 consumes around 5Watts, and at that consumption manages to outperform the PS4 and Xbox 360 (running at ~100W). Check out our other Nvidia articles on the topic.

5watt at peak.. yes I saw that comparison with consoles too (which most of numbers are inaccurate).. but 5 watt means 1.5 hour battery life fore 9watt hour tablet battery.. ARM chips usually run at about 1-2 watt for regular use.. and for most tasks less than 1 watt.. so 5 watt is for highest clock possible which isn't practical . ARM cortex-A15 at 2.3 ghz can consume battery in a heart beat... anyway we must wait for more real world battery data.. Im sure Tegra K1 can't reach 2.3 ghz in their regular version, may be an updated shield with a huge heatsink can handle this frequency.. but for a 28nm chip, it cant be done.. or may be Nvidia can make this SoC in 20nm lithography

5W is low enough for this to go in small tablets and upwards. So, the 7 and 8 inch tablets with the potential of a serious gaming console are coming this year. And when this chip gets a die shrink to 20/16nm, it should be good for smartphone use too.

cool features? with tegra 4 nvidia introduce a few cool feature like chimera and direct stylus. but it the end does device manufacturer use it? no. nvidia have to come out with their own tablet to stress out this feature so people will know about it. i think nvidia learn from that and did do much 'cool feature' of the SoC. instead they focus on performance.

I agree with this. Nvidia want to bring gaming to a mobile device and forgot most important things. What do peoples to do with theirs mobile devices and I doubt gaming is theirs 1st priority. Running heavy games, means CPU/GPU will get hot and have they fixed the issues with overheating yet with theirs Tegras SoC? Games with beatiful graphics, means its big and will take alot of space. Most devices comes only with 16GB, alot with no ext. SDcard slot and gamedata on sdcard isnt support by all games either. So its alot of hurdles Nvidia have to think about, to make K1 a big succee and with theirs Tegra SoCs failures with the heat issues. Impressive specs on paper and big fail in real usages.

anandtech already out with article analyzing tegra K1 architecture. in regards to power consumption nvidia demoed that at same performance as A7 and Snapdragon 800 the soc end up consume much less than both. of course when it actually hit the device it can be different but if manufacturer can make it right then the power consumption will not much worse then current gen SoC http://anandtech.com/show/7622/nvidia-tegra-k1/3

Those Days aren't far away in which we'll be able to play Forza Motorsport 5 on our smartphones.

I don't want to think about it, since Forza 5 was already outdated the day it came out :p. It's a console game. "next gen" is already outdated :p

Soory, but this does not impress me, we are not going to be using our phones just for gaming, how is it going to improve photography, what about lte, of course there is no lte, Qualcomm are qay ahead because their chips are made to cover all aspects of a phone. There are new features to help with both gaming, photography and other areas too. Qualcomm already have agreements with many phone manufacturers for their s805, i'm afraid for Nvidia it's curtains.

for photography nvidia already have chimera (debut with tegra 4). nvidia soft modem for lte already certified by AT&T but right now it is still remain unclear what nvidia will make of it. JHH even mention they particularly not targeting US market for their lte. in tablet space tegra is doing fine. if not nvidia can just do what they did with TN7

for photography stuff and video this is the improvement made on tegra K1. nvidia just improve what already existing in tegra 4: http://anandtech.com/show/7622/nvidia-tegra-k1/4

Great hardware! Hope the game titles could catch up. No mention whether it's opengl es 3.0 compliance.

the gpu will support direct x 11.1 and OpenGL 4.4. that already covers beyond OpenGL ES3.0

This is just a thought but what if we get a SoC hybrid between Qualcomm CPUs and nvidias GPU

This is very much possible, because Nvidia said that, they will license their GPU on K1, to other manufacturers, but let's see if qualcomm will license it or use their own GPU....

qualcomm will not license other gpu since they already have their own gpu IP (adreno) unlike most soc maker out there.
