How Video Card Works

Modern games have amazing graphics especially on the PC but no ever computer can handle these graphics why is graphics cards obviously a good graphics card can go a very long way in providing us with extremely high graphic game experiences.  But how what exactly is a GPU and how exactly is it different from a CPU why do we need one. Today game ranks ask the question how do graphics cards work so when new battlefield games come out what does everybody talked about immediately the graphics of course the graphics it’s the thing you see first no matter what you don’t get to see something else and say you’ve seen the game.  Visually what a game looks like matters a great deal to us  and while I like to talk about art style a lot there’s a lot of technical Jargon  behind. What goes on in order to bring you representations of what’s going on  in an imaginary world so to start off computers a CPU and a GPU when described  sound pretty similar a CPU and GPU.



Both do math they both solve problems and  give you results that looks entirely different on a screen that it does  inside a series of transistors and wires and processors bouncing electrical  signals around saying yes or no over and over and over again at incredible rates  so to put it in the most simple possible words a CPU. It can do things in a much more linear way than a GPU, a CPU may have a few course – 48 however many the number isn’t really relevant but that’s the number of streams of operations that a CPU can do at a time one per core.  Now it’s important that a CPU exists because some things that are very complex need a more dedicated architecture to continue to process those operations but the way a GPU works through technologies like Cuba. Compute unified device architecture which was actually developed by in video and therefore not the only technology like this but the principles that apply to Cuba basically apply to most GPU technology.  If not all is kind of like and when I say kind of I mean kind of like a lot of  little CPUs, now the reason I say kind of and not exactly like is because the course of a CPU can all be dedicated towards different problems. Whereas all of the  sub course of a cubic or have to be dedicated to a parallel problem like, I don’t know graphics and that’s over simplifying it just a little bit as  graphics are several sub routines but essentially a lot of little cores are  solving somewhat simpler problems than what a cpu might be used for much faster.  Because there’s lots of them  and what I mean by a simpler problem is like geometry in all honesty a geometry  problem is really just a few computation and if you have a ton of course  dedicated to it at once it’s going to get solved very fast.


Geometry is just shapes  and trajectories and variables that affect placement and angle and things  like that  easier things to do but when presented with a limited amount of course what  kind of clogged up the workflow  let’s say you’ve got an eight core cpu and you’ve got a hundred different  geometry problems to solve well. They take up a court until you get through the hundred but imagine if  you send the same set of geometry problems to a multi core graphics card  with hundreds of sub course ones that are made for a specific purpose and that  purpose is geometry to tackle that geometry as fast as it can  with a horde of processors. Well that would be generally looked at as a much more efficient with doing things wouldn’t it and that’s why a GPU is so much better at rendering graphics than a CPU sure there’s nothing that would stop you from playing a game on a CPU but there’s a reason why the CPU is generally used for things like artificial intelligence because they’re much more complex operations that take a longer period of time to do. When you have a limited number of data streams you want to be using the data streams in the most optimized way and if you have one type of processor that has a limited amount of cores that are all held up on specific things you would probably want to throw the more complex. Singular operations towards that whereas if you have geometry oriented problems that can be solved quickly. You have a lot of those problems you would probably want to solve those with lots and lots of small cores and they’re all geometry oriented and therefore easier to solve by a GPU.

So I’d like to send them that direction and it will handle it much faster than if I  sent them towards the CPU, I don’t know if you  remember it I do it was a while back  it’s okay if you don’t know it’s important to say that you couldn’t just  throw anything you wanted a GPU. Do it faster that’s just not true complex problems often involve multiple threads of information going on at once and as I said on a GPU the problems have to be parallel. Well if the problem diverts in some way from what one would consider parallel it’s not something that a GPU is going to do very fast at all.  The main reason it’s so good for graphics is it can do so much of one  thing at once  graphics routines are fairly straightforward and don’t go into  uncharted territory too often.  It’s not trying to simulate anything other than fairly straightforward processes. If I drop an item it falls okay, if wind hits the cloth it does moving. If you look at the Sun there’s a lens flare that type of stuff in which the result is always going to be the same or very similar and stuff that is  going to need to be done a lot like we’re all the vertices are and how many faces are painted in between them a vertex being a corner. On a shape and a face being a surface that’s drawn between three vertices that may be smooth or textured or utterly flat given that way cool retro look.



Essentially now you know what a GPU is and why one uses it and what it does granted this are actually a simplified version of all of this and there’s a lot of theory that can be talked about. I’m sure that will actually get into deeper conversation if we all meet in a small conversation and open our big traps to talk with each other.

How Much VRAM do you need When Running a Game

One of the most common questions we get around, especially when a new graphics card launches is Halite Assert Keys because you shouldn’t ask him now. Maybe he knows more than you guys think how much graphics memory do I need well that is a very good question I mean Nvidia and AMD just launched new versions of their top to your graphics cards with eight gigs on the MD side on board. Like eggs around so who are those actually for why would one need double the amount of Vram that was previously offered will have the answer for you right after these messages Club 3ds MST up can run three monitors off one display. No daisy chaining required, now to learn more before we go any further with this topic I guess let’s start at the beginning what the Vram well it’s a specialized version of dynamic random access memory or D Ram similar to the way your normal system ram keeps the cpu. It fed with data the Vram keeps your GPU or graphics processing unit fed with the information it needs to render images to your monitors the vram holds textures the frame buffer.

On any other assets that are required to render a frame like shadow maps bump maps and lighting information because it’s much faster for the GPU to pull off of that extremely high speed memory. Right next to it then to pull from your hard drive or SSD or even from your system memory so then what factors influence the amount of Vram that’s used by your GPU well one is monitor resolution that’s because the frame buffer is used to store the image as its rendered before and during the time is being sent to the display the resolution.



Impacts this directly so games are all rendered at 32-bit color depth unless you specifically set them to do something else so that’s 32 bits per pixel x 1920 x 1080 for 1080p. So a single frame would be eight point three megabytes a 4k image would be a whopping 3840 x 2160 by 32 which is about 30 3.2 megabytes quite a lot more. The second factor that affects memory usage is anti aliasing basically in order to anti-alias an image or smooth out that Jaggies more pixels need to be rendered and then smooth to reduce that staircase appearance. As you increase the sample size as you take more and more samples this can have a massive impact on memory usage, So now you know that resolution anti-aliasing are two major factors that affect the ram usage but what are the numbers tell me what I need exactly like this well a tricky thing it depends completely on your game. In every game you’re running like the Minecraft at 4k is going to have very different requirements from something like Skyrim with the high quality texture packs because the actual quality the resolution of the textures themselves within the game has a huge impact on how much Vram is going to be used. A bit of an example when the gtx 680 came out it only had two gigs of video memory and that was plenty but as games have gotten more and more detailed more Vram has become required to hold higher quality texture so games that aren’t optimized correctly. Just are able to render higher quality images are going to fill up a larger be around so that’s why something like the GTX 770 which is actually based on the same GPU as the 680 is available with a three gig frame buffer. Even though that GPU is not more powerful because the way that the games were being developed had just changed even in that short period of time now there are a couple of mini myths about the ram. We should probably address as part of this video first lots of users think that crossfire or SLI will actually scale the amount of the power to your systems.
You’ve got like a four gig good gtx 970 who happens to be exactly what I have to figure, you got a four gig gtx 970 and then you add in another four games gtx 970 so I’ve got like <operand> two </operand> gigs of the year. No wrong actually the way that multi GP workloads are handled the Vram is cloned across the card so both of them have access to exactly the same assets at the same time so even when you have four of these gpus.
In the system at a time although you can’t really do that because they’re 970 is the only running through it but don’t worry too much about that even if you had four of them you would still have effectively the same amount of the ram for gaming. As if you were running a single card and this also applies to dual GPU cards like the titans X or the R9 290 5 x2 which have 12 gigs or eight gigs of ram.

Actuality that six gigs and four gigs of usable Vram/graphics card respectively second despite what you may have read online you cannot SLI two different cards that have a different amount of Vram on board the word on the street is that they’ll just use whichever one has less they’ll each have effectively that amount of Vram. But it doesn’t work that way AMD crossfire on the other hand is a little bit more flexible and allows mixing and matching of GPUs and even video ram amounts but of course the card with more memory while that extra ram. Just gets kind of thrown out the window bird is that more video memory does not necessarily mean better performance and every time if a game uses let’s say fourteen hundred megabytes of RAM adding two more gigs won’t make a difference because you won’t be using it anyway. On the flip side not having a not be RAM will degrade performance drug magically you’ll get texture pop-in stuttering and just proportionately low performance an example of this, I was running Shadow of Mordor by accident on a 4k display with the built-in super sampling option. I was running effectively at 8k so I was running two hundred percent super sampling and instead of you know dropping in performance by a quarter it dropped in performance from like 55 FPS.



Because not having enough Vram is disastrous and thing to bear in mind when you’re shopping is that GPU vendors use some common sense when they’re deciding how much memory to put on a graphics parts off high-end GPU that can run you games at Ultra settings in your high resolutions. Isn’t going to come with 512 gigs of ram on it more often than not it will have three gigs or four gigs because the GPU actually has enough horsepower to be able to render the image that would require that much Vram. If you’re buying a low-end GPU sort of the opposite is true there is no point putting three or four gifts on it because by the time you’re going to try to render that image it’s not going to have enough power to do it anyway so how much beer am do you need well basically arm the long and short of it.
I guess this is more long than short is very his no clear-cut answer games are constantly evolving graphics cards are constantly evolving some games are going to need more some will need last I mean we’ve seen games that are just highly optimized and sometimes it’s another word for not very demanding blizzard games for example we’ve seen ones that are not so by guessing games such as Watchdogs. So we can’t tell you guys exactly what amount of work that’s the other thing is morning like skyrim can use anywhere from very little to times if you throw third party mods at it with like extreme ultra definition textures and stuff like that. So basically if you want to get the most out of your budget the best thing to do is talk to people use assets like the NCIX forums or Linux tech tips for more nice people can help you decide on the specific part for your use case scenario lost pretty much it.

The Ultimate Compact Video Card – R9 Radeon Nano

Single card graphics solutions become more and more powerful we’re seeing many builders ditching the bulky full and mid tower two cases with multi-GPU setups in favor of smaller systems that still pack a powerful punch but with most top to your graphics cards having sometimes Ludacris space requirements. Generating lots and lots of heat putting them into something like an ITX chassis can be a challenge with that in mind MD delivered upon this world the Radeon R9 Nano a small form factor graphics card that promises performance on par with full-size flagship Radeon Cards.
But can team red deliver and give  us a truly first class gaming experience in such a tiny little package  stay tuned to find out and if you want us to do more  theoretical graphics card comparison videos in the future  very vague. I know the master case 5 by Cooler Master gives you the freedom to truly make your mid tower pc case your own with a variety of modular parts and accessories.




The  official name of Radeon R9 Nano is the Nano, the R9 fury series of  graphics cards from AMD which also includes the R9 fury the top and water cooled r9 fury X and despite the Nano being much smaller and less bulky than  the fury x. It shares the same GPU with 4096 stream processors and 64 compute units the only difference being that the Nano has a peak clock speed out of the box of 1000 mega hertz.

Which are 50 less than the fury X the net also has the same memory configurations the furious with four gigabytes of high bandwidth memory AKH P.M. running at 500 megahertz on a 512 the gigabyte per second memory bus. However where the Nano sets itself apart is its cooling and power delivery systems unlike some other reference design cards from AMD we’ve seen the Nano has its heating fins oriented horizontally along the card. Instead of radically out of the card you’d see a radial design set up very often on Intel stock CPU coolers. They did this they moved to horizontal to minimize obstructions and  make the cooler function more similarly into a blower style solution AMD is targeting a temperature of 75 degrees Celsius. While gaming with this card throttling at 85 degrees Celsius the Nano is also a lot less power-hungry peak board power is rated at 175 watts compared to the 235 lat draw of the fury. Fury acts be improved cooling and reduced power consumption  combined with the space saving benefits of HBM which is physically integrated  into the GPU package means that AMD was able to make the Nano PCB only six  inches long  so the card only extends as far as the end of your pci express slot.



On your motherboard do keep in mind though if you’re interested in dropping the Nano into your ultra small system that the power connector alone 8-pin pcie input is oriented on the side of the card not on the top. Meaning you’ll have to factor in  some extra length there  for your plug coming off of your power supply with that said let’s have a  closer look at the card itself  starting on the front you see a matte black metal shroud it looks quite  similar to what we saw on the fury X.  Except of course that the Nano is an air-cooled card so there’s a single 90  millimeter fan on the front cool everything down  do note that if you pick up a reference Nano the Heatsink and fan are actually  integrated into the shroud and therefore are not easily removable should you be  interested in Modding the card the heat sink.
Itself features the after mentioned horizontal thins and no heat pipes which AMD decided to omit to keep the weight and bulkiness of the card to a minimum while still keeping the cooling good the back of the PCB is bear though it does have a matte black finish for a clean look we want to the top we see a fairly understated design with the radeon logo.
And only a small part of the Heatsink peeking through the black shroud and then the side of the card is open to allow case fans to help move air across the heatsink and also includes that loan 8-pin pcie power connector we mentioned earlier on the back we see one HDMI.

Three display outputs note that this doesn’t have any DVI outs and we didn’t see any adapters in the Box to make sure you pick one up if you’ll be using DVI with this card now onto performance we used a fairly standard test suite of Tomb Raider,  Crysis 3, Far cry 4 and the Witcher 3 for our standard performance benchmarks.  Then we just added on fire strike ultra which was a little aggressive but interesting regardless then we did our standard sky box testing and Crysis 3 to test heavy low temperature and system wattage from the wall one very important factor to remember when looking at these numbers is the size of the nano.

Sure its trading blows of the gtx 980 and it’s being beaten by the fury both of which are cheaper but this thing is absolutely tiny in terms of size while the 980 and fury are both center of attention case monsters this shows in power draw as well the only card that beats the Nano in terms of power draw. We tested is the now old 285 compact from sapphire which to be fair is it a much lower to your performance which shows very well when looking at the graph comparison of system wattage per frame.  Even though the nano has a little  a bit more power draw than the 285 compact its system watch for frame is  under half which is pretty great  this leaves us with a card that when compared to a 390x tricks edition  performs better runs cooler and draws significantly less power from the wall.

All while being much smaller but at an increased price of two hundred dollars which brings us to our last question price. You got me it’s not exactly a cheap card at six hundred fifty  dollars it’s got a price tag to it  it’s dollars per frame is not really that great surprise performance is not  really that great but I honestly don’t think that’s the reason why someone  would be interested in this card.



The card isn’t trying to be the best price performance cars on the market it’s trying to be a badass in terms of power consumption and performance while containing itself in a small package and that honestly basically was my conclusion the Nano is small. The Nano is fast and the nano draws an impressively low amount of wattage from the wall it does all of this wild yes being a little expensive but not to an impossible degree.

I could see a lot of small form factor builders looking in  this direction soon especially with the number of case manufacturers coming out  with smaller and smaller cases every year with some very interesting ones on  the horizon  with the raintree V DOT 0 SDK. Which is one small snippet of code you’re all set up in less than 10 minutes they even have support staff ready to walk you through the process over the phone?

If you need them their code supports Android iOS and JavaScript clients and they have SDKs in seven programming languages they make it easy to offer multiple mobile payment types including PayPal Apple pay Bitcoin VeMo cards and more all with a single integration they have quick knowledgeable developer support if you have any questions and if you want to learn more and get your first fifty thousand dollars

Record Console Gaming Without a Capture Card

So you want to record your gameplay by don’t have a capture card well you’re in luck because there is a way to do it.  It’s not the best that get right out of the bag and not the best way of doing it. But a lot of Youtubers to start off this way the main thing they want to be two best friends play indie games. They start off doing this method as well so your practice and I’ll post stuff here on how you start.  So the first thing you’re going to need is a video camera  I’ll have mine because I’m using to record this right now  you’re very camera set up a couple things that needs to have the ability to  record video In the video report audio.



Now if you want to go one step further check out to see if your video camera has in a mic in port and it would have a jack like a headphone. You can use that plug your audio into because nothing worse than crappy audio was innocent. Now this is some good audio the thing you need to capture that sound is this cable it’s a mini to RCA and I’m then of RCA cable, I have a barrel connector. Our state barrel connector now what you’re going to need to do is take your  component cables and you’re going to plug that into there and then you’re  going to take this end and plug it into your camera.

Another thing you know what this is you can’t use an HDMI cord to do it because audio goes through HDMI into the TV so you need to have like this thing.  Take that off three colors audio cables and this one is got PS3, Wii and Xbox on it.  You can buy those, wherever I don’t know another thing that will be really  helpful in this case is a tripod,  this is a really crappy tripod but a tripod on the less the track gives you  the ability to adjust it seeking center  everything has it’s not centered section. First thing you want to do is take the  camera and center it as best as possible  leaving some room around the screen to work it and once you think you got it  pretty good.  You want to slowly zoom in and see how it looks now you may notice that it looks a little crooked and in that case tilt and pan your tripod raise it until it looks pretty in the center.


It is going to take some playing take a lot of playing with until you get a perfect but it can be done perfect.  It can be just now once in your game you’re going to notice if you plugged in the audio jack that it’s blaring loud. So you can try setting it on your camera because like the nature of the game structure of TV you have to go into your settings on your game. You have to lower all your audio if you’re game doesn’t have this capability or pause and have a bad time. I know Halo 4  doesn’t have this capability and its really annoying the state at least  you’ll notice that it doesn’t look perfect but it is something you know, it’s a good way to practice because I personally don’t have a capture card  myself but using my DSLR camera.

I have the ability to practice and do this and I’ve got people to start  watching this defense with some pretty good but it’s again it’s not a  flawless thing and it is for practice  not a permanent solution to a problem.
