hotspot Shield service makes your internet browsing safer more secure and fully private click now to learn more there are a few things that get us more excited around here that high-end graphics card launches and as far as single GPUs go the GTX 780 Ti is about as high-end as it gets we'll start with the tech specs it has the same gk110 lineage and Titan DNA as the GTX Titan and the GTX 780 it also has a full 2880 CUDA course that is 25% more than GTX 780 that is a full-fledged gk110 core it is clocked at an 875 base clock 928 boost clock clock speed meeting we have not only more CUDA cores but also higher clock speeds and it comes with three gigabytes of gddr5 memory at 7 gigahertz on 384 bit bus so we're actually getting faster memory as well physically the card looks pretty darn similar to the last gen so there's two sli connectors with support for two three or four-way SLI you've got that same acoustically optimized fan with the slow ramp up and down so that it's less jarring when it has to speed up or slow down we've got a cast aluminum shroud with dark aluminum fins visible through the polycarbonate window so those are mounted on a vapor chamber that takes heat away from the GPU on the back of the card we have two dual link DVI ports HDMI and DisplayPort now with support for 4k and triple surround however I maintain that this is pretty expensive and kind of irrelevant right now I think it's just a feature checkbox that they want to have compared to the competition we've yet to see a gaming rig with a 4k monitor on it posted on the lines tech tips forum so I'm just not convinced that it exists yet at the bottom we find the PCI Express 3.0 16x connector and then at the top to correspond with that 250 watt TDP we've got an 8 pin and 6 pin power connector the cooler is a blower style design so while a little bit of heat is going to be exhausted out the back of a card into your case most of it is going to be exhausted out the rear of your PC case so that it doesn't affect the cooling of your other components we've got the usual effects in terms of in-game technology DirectX 11 ambient occlusion TxAA tessellation physics and there are some upcoming games and hot new titles that support these features on the screen right now hopefully there's no mention funnily enough of 3d vision but don't worry guys it's still very much supported I just guess that that particular trend didn't take off the way that TV manufacturers and some other folks hoped that it would g-sync on the other hand is a game changer it looks dramatically better when the framerate is variable at all which happens in every game as you move from more or less demanding scenes and in between them it dynamically adapts the refresh rate of your monitor that is how many images per second according to the frame rate actually being output from your GPU now it does rely on hardware support but we're expecting to see monitors sometime in 2014 you'll also need a Kepler based GPU and hopefully from the manufacturers that you see here that are already partnered up we're going to see great high resolution high refresh rate designs with a variety of different panel types whether it's TN or IPS or whatever else and these are going to come in at reasonable prices because trust me guys I'm one of the several people on earth that's actually seen this it is amazing and once you try it you are going to want it GPU boost 2.0 functionality has been tweaked some what with their power balancing feature and Luke will tell you more about that after but fundamentally the technology hasn't changed much so it's monitoring voltage temperatures power consumption and clock speeds in order to deliver the most balanced performance at any given time without exceeding any of those parameters now there's a difference between how AMD views balanced performance and how in video views balanced performance with this generation it runs substantially cooler and much quieter than the r9 290 series but there were some things that we didn't necessarily like about this implementation there's very limited control in terms of voltages and power limits it gives us a whopping 106 percent power limit maximum and even with things like temperature settings it seems to be ignoring what we say anyway we set a maximum of 95 degrees because we were like go to town I mean AMD set 95 degrees let's run it 95 degrees I didn't run at 95 degrees so it just ran at 83 degrees so it doesn't even seem to seem to be taking our input as Destin's with that said we still achieved over twelve hundred megahertz on the core so that is one hell of an overclock and very beastly performance as you guys are going to see so maybe it just runs at eighty three degrees and that's all there is to it this could be partly due to the larger die as well as the more mature design so a larger dial aoz you to inherently spread the heat out more easily using the heatsink GeForce experience continues to get updates but first the stuff that hasn't been changed it still gives you automatic driver update so you get a little notification in the corner hey you got that new game hey there's a new driver to go with it make sure you install that yay it also gives you optimized settings for your games and there's actually quite a complicated process to determine these actual people sit there and play the game find benchmark able segments that are demanding then they determine a target frame rate for these demanding segments way graphics settings against each other you know play around the sliders well does this actually make it look that much better and how hard is it for the graphics hardware to handle and then they find the best settings that satisfy the FPS target and still make it look as good as possible then they run all that information through automated validation across thousands of hardware configurations in order to deliver you a playable gaming experience I've tried it and it works I ended up tweaking a couple things further but the great thing about GeForce experience is that you can have it deliver better graphical fidelity to high-end gamers who don't want to tinker with things you can have it help low end gamers like you can see this example with a GT 540 m achieve playable frame rates even on low-end machines and most importantly for people like me we're going to tweak things anyway you can install it then completely ignore it and do everything manually through the driver now onto the numerous stuff now these next two features do require GTX 650 or up you have to have a Kepler GPU with a built-in h.264 encoder but man are they cool game stream is awesome I've been using an Nvidia shield to play Batman Arkham City because I'm a little bit behind on the Batman franchise using the GTX Titan in my desktop PC and then a very solid wireless router guy's a beast wireless router is required I'm using a Seuss's AC and 66u or whatever it is but it is amazing PC grade graphics on a handheld or with their new console mode for shield you can stream them to your TV at 720p or 1080p with an upcoming patch that's coming later on and when you factor in that with high-end graphics card 717 up you can get $100 off a shield that's a $200 add-on that is essentially a PC game console adapter thing for your TV and a handheld that can stream from your PC it's pretty freakin awesome and then next up is shadow play right now it supports local recording only although twitch streaming integrated into your graphics card driver essentially is coming soon it records at 60fps at up to 1080p so it's better than most standalone hardware recorders and it can just record passively in the background so you can kind of go oh well that was awesome I want to grab that and you can actually retro actively grab up to 20 minutes of pre-recorded footage in Windows 8 using their passive shadow play mode or you can have unlimited recording in manual mode now it's not perfect it's like not perfect yet by all means but I mean there's no OpenGL support so no minecraft guys but it has very very small file sizes and the quality looks great and it is a negligible less than 10 percent performance impact so it's something that you can actually have running all the time which is very very cool for game streamers compared to software recording like fraps so that's it for the tech now onto performance we ran all of our graphics cards on our standard overclocked 39 60 X testbench all video cards were overclocked as usual if you want stock benchmarks there are a hundred other guys that do things that way so go for it go look at their benchmarks you can see our overclocking settings in the Google Doc link in the video description if you have any questions about how we overclocked the graphics cards or what frequencies they're running at we recorded frame rates using fraps after giving each graphics card a few minutes to warm up in game this is important because the way GPU boost 2.0 and power tune adjust performance based on temperatures it's a necessary step for getting accurate GPU performance so without further adue over to link just so you guys know the overclocking dock is linked in the description below and has all of our settings for all of our cards and just in case you haven't seen it yet on the far right side there's a new column that we introduced a little while ago called core clock actual which is displaying our observed clock speeds for the cars with GPU boost 2 and all these new technologies they happen to throw back quite easily so what we're showing is not what we set it at showing is what its actually performing as and our card is performing quite well at twelve hundred and fifty six now that's with an offset of plus 250 if I ignored the crashing that I was having in Tomb Raider at higher clock speeds I was pushing easily 300 the charts have been pretty self-explanatory thus far with the 70 tee I pretty much crushing everything although that does make sense due to its much higher price point that's something that you have to keep in mind the question that is most likely on quite a few of your minds is what happened to the Titan a it's not in your benchmarks B it's a slower car to see it's much more expensive well it's kind of a developers card now it's not really a gaming card anymore it has that double precision feature on it which is kind of awesome for certain developers that can actually utilize it and other than that it's just kind of sitting up there by itself if you're looking for an extremely high-end gaming card and you were looking at the Titan I would maybe divert your focus to the 780ti you may need that six gigs of ram I have noticed in some of our higher resolution benchmarks that it is starting to utilize a lot of the RAM and getting fairly close to its max although not that close mind you so one thing to do if you need that extra RAM might be wait a little while and see if those different versions of the 780ti coming on later we have no idea but I hope there is because that would be very interesting I'm sure a debate that will go on is is this card overkill for 1080p I would not say quite yet in Far Cry 3 in Crysis 3 with all the settings max we don't get our average FPS over 60 and I would personally think that the perfect 1080p experience would be 60 FPS plus and with stars' isn't on the horizon we don't know what's going to happen there but it's probably going to push it even harder so I could still see this car being justified for 1080p but I might want to go a little bit higher and where this card really shows its prowess is in the higher resolutions are 2560 by 1600 benchmarks were very impressive although again in Crysis 3 we saw a little bit sub 34 our average FPS so I would love to see two of these cards unless a live start crushing games in those higher resolutions this card is kicking butt and takin names but it definitely comes with a price tag in the comments below are you going to be looking for a card like this with a premium price tag but with that level of experience or are you going to go for something more like say at r9 290 where you can save a bunch of money and it's a little bit hot and heavy but you're still getting a lot of performance out of it what do you guys think if you like
