hey guys its Darcy like eBay here from android authority one of the best android sites in the world we're reporting live from las vegas we're here at CES 2013 now we just had the privilege of attending in videos press event here and they release some amazing technology they debuted their Tegra 4 SOC now what we're looking at here is an arm cortex a15 quad core chipset the GPU incorporates 72 unique GPUs it's going to be remarkably powerful and in their demonstration they showed us that it just completely demolishes the a-15 dual-core exynos 5250 featured in the Nexus 10 they were able to load 25 web pages in like 27 seconds something that most powerful laptops today can't even match so let's check out the Tegra 4 is android authority here with Darcy llueve reporting live from CES 2013 you places of our properties attributed to probably great surprise to all of you like engineers the temperature we just need a lot more performance and here today I'm here to prove it to you I'm here to prove to you that we do a lot more perform step 4 has 72 GPU cores listening is flooded which engine course I just wish we could flood even more cheating whores in here second thing is it is the world's first part 48 15 2015 which is arms new cpu architecture and quite a bit faster than our last generation we still have our power standing water that's global power cord that comes along sips local it's a power when you're mostly doing local community regarding water while you're reading a book or just browsing the web site or so you enough and then of course every mobile processor in the future we'll have to be connected and fortunate obviously the next step and include a fortune emmaus first 4g LTE other so poppy shows now please and so this is on the left is the nexus 10 and we'll going through websites your Amazon's website cna on New York Times and on the right is jigar floor we're cranking along and these are these are web pages that you see you know everybody misses on a daily basis and it hit a sign if it's not clear already got a ticket for it is a is doing quite well and so you took about twenty seven seconds to load 25 unique web pages a real world example of an application that we do all the time now of course all this basically means is this if you're unloading a website which I go for it comes to the second basically like them if you're learning to web page with the fastest android tablet of all today nicely and rajendra nexus 10 it would take two seconds now frankly i think i think one second is welcome twice as fast it's two seconds today's a camera works like this as a sensor goes into an image signal processor which takes the what is called the bear cabins in terms of it in the process it advances the image quality extracts the luminous address Roma and reconstruct what looks like to give a JPEG image what nvidia tegra 4 architecture does is something radically different something radically different we introduced a brand new way of designing our chip so that we could put our processors closer to the imaging tightly the first thing that you see we'll just go back this is all this is Duke the first thing that you notice is that we take two shots at once which a two shots at least one shot with high exposure launch of the light exposure then the first thing we do is we dumped it into this computational photography pension sitting in system memory and once we do that this engine for the left could now take advantage of all the processors on chip that's why we have 72 court that's why we have 48 15 that's why we got this powerful iced tea and with this computational photography we could do the necessary mathematics so quickly that effectively at the end of shy you have his yard weather for does it as we go pam pam reject your shots do simultaneous shots and then all processors are deployed and running to do the alignment of war be the registration the tone mapping all of the necessary image processing and who goes out one single foot it basically is a one-shot deal what comes out of the chip right off the bat is HDR what that means is every software application today just works no modification necessary no authority necessary you can either decide I would like to have HDR on all the time and then as a result in that particular case it was just a google camera became nearing the door and it is totally HDR nice to illustrate the benefits of software to migrate here or this software modem technology compared it to the state-of-the-art del tema it is so much smaller than the reason for that the reason for that is this architecture was this programmable architecture was designed for motive technology and because it's able to reuse reuse each one of the processors for every stage of the pipeline it doesn't have to replicate any special she wants frankly if Nvidia today in our industry in graphics was still using fixed function processes in order for us to deliver the type of visual only that we're seeing today then chefs would be many times partial as well we were so enamored with this technology we took a chance and I drop and try to find the second that we are now sampling a 4g modem based on the strange acknowledged let's get this guy from across
