Nvidias 3D Vision vs Ati Eyefinity, Which One Holds The Power ?

Posted by driveout on February 10, 2011











The amazing Nvidia Gpus offer great gaming experience with Nvidias physx, cuda, purevideo HD technology, SLI and most of all 3D Vision. On the other hand Ati’s extreme Eyefinity, Eyespeed, Avivo HD, Crossfirex and HD3D technology creates a new meaning for gaming. Which one offers better features for Gaming, Movies and all around use ? Read on to find out !!

Nvidias Features

3D Vision enables users to fully view content in 3D. This is a major step up as its no longer 2D and gives users full control of gaming, viewing photos plus more in true 3D. There are two types of 3D visions the basic home edition or the pro. Home edition is for normal users it works for Games, Movies, Photos, Blu rays, and I think even websites. The more advanced Pro version is used for Cad, 3D video editing and anything else the 3D vision is capable of. However it runs around $200 dollars which might be a problem for some people. Considering that a regular monitor wont do it, you will have to shell out a few more bucks for a 120hz screen.

Physx is a new type of engine used in games and movies. Its called a physics engine SDK and its used to enhance the gameplay and to simulate real time experience. This engine is mostly used to improve the 3D environment of games as well as graphical performance. This means all those explosions, bullet holes, flames,blood, buildings collapsing and more are all processed by the Nvidias Physx Engine. Whats new is that before most of the load was on the CPU but what the Physics Engine does is it transfers all of it to the GPU allowing the CPU to process other tasks. I found a great site explaining it to the max check it out

Cuda what is it ? Well im not entirely sure. From what I read is instead of normal GPUs that just process graphics Cuda enables GPUs to act some what similar to a CPU. How this helps is instead of just rendering graphics the Gpu can be now used to process other stuff as well. Whats different about it is Users can use C codes in Cuda allowing users to program tasks. Not only that but Cuda increases the performance of graphical use, and helps out in video editing and other programs as well.

Purevideo HD Technology delivers great picture quality. The way it works is it has a separate video processing core on the GPU. Once again this allows to do multiple things as the load is off the Cpu and the power consumption is lower. Like mentioned it provides great video without no distortions and free of stutters. One of the biggest reasons for it is the support and acceleration it provides for blu ray and HD DVD movies. This completely transform the experience of HD movies on the pc.

SLI is Nvidias way of connecting and scaling graphical performance by running 2 or more Gpus. Running with 2 cards boosts up the performance to twice as much while when on 3 cards the performance is at 2.8x so almost 3 times as good. How Sli works is one card processes the horizontal frames while the other card processes the vertical frames resulting an increase in performance.

Alright, now its time to get into the Ati Features and see how they compare to Nvidia.

Ati Features

HD3D is Ati feature that transforms 2d into 3d. Just like Nvidias 3d vision a 120hz monitor is required as well as glasses in order to view the 3d image. HD3D is only available on the 5000 series cards and up. Same as with Nvidia this feature allows users to play games, movies, and view photos all in 3d.

Eyefinity definitely makes a big difference in all around use. What Eyefinity does is allows users to hook up multiple monitors to the gpu. Currently I believe you can have 3 monitors hooked up to one Gpu which is  awesome. This is a great feature for heavy multi taskers as it allows plenty of space on the desktop to run multiple programs on different screens. For instance on one screen you can run photoshop on the middle screen you can have a website opened and on the third screen have a movie running how fantastic is that. One more cool thing is when gaming the game displays across all three screens and usually your fov (field of view) will be bigger.

Eyespeed and Avivo HD kinda go together with each other as they both accelerate and increase the quality and smoothness in videos/other tasks. One major thing that Ati includes is the (UVD) which is unified video decoder and what it does is it offloads your cpu so that it can process other stuff while still having that eye candy in movies and games. Avivo hd plays a big part in watching Blu ray and HD DVD movies as it increases the performance resulting in no lag.

Crossfire x is Ati’s way of running multiple Gpus, the way it works is a little bit different then nvidia. Ati gpus instead of processing horizontal and vertical lines they process tiles. The screen is divided into tiles and then each gpu processes a separate tile. This does not mean that its faster or better but it does increase the performance. To get a better visual think of a checkerboard.

Which Ones Better ?

In my opinion they both have their pros and cons. Nvidia and Ati are pretty much right on each other as they both offer the same features but in different ways.

Sli vs Crossfire, supposedly Sli is better as the performance it offers is slightly greater then crossfire and sli has better drivers support as well.

As for all the other features its a tug of war between the two and no ones really sure which way it will go. Both Nvidia and Ati offer great amount of features to be explored and I would say you cant go wrong with either one.

Direct X Differences

Posted by driveout on February 5, 2011

Hmm well iv been looking around to find what the real difference is between all the DirectX versions and they are not big. As far as i have found the only games you can tell in is Crysis, Resident Evil, and Lost Planet. My guess is most people wont be even able to tell the differences between them. Heres a video comparing Directx 9 to 10.

Now heres the difference between Directx 10 and 11 if you can see it because i cant. Well actually if you look at the bushes and trees you do notice a small difference.

Anyway In my opinion the differences between all the Directx versions are very small and hard to notice. Maybe if your gaming in 1080p on a big screen tv then I believe it would make a difference. Otherwise If you have Directx 10 I dont think its worth upgrading just to have 11.

Check this out if you want to know more about Directx

How To Choose A Video Card

Posted by driveout on January 23, 2011

As mentioned before in the basic guide theres two options: ati or nvidia. Which ever you pick is personal preference. Those are the main two brands but theres a bunch of sub companies that make the cards. For instance companies like XFX, Sapphire, HIS, Diamond, Visiontek, ect make Ati Cards. While Sparkle, XFX, PNY, EVGA make Nvidia Cards. Now that we are through with the brands how do I know which one to choose? Well let me divide it into three groups.

Easy – This group is for people who dont play games. They use their computer for basic use such as web browsing, mail, maybe some movies and easy tasks that dont require a good graphic card. If thats you dont look at expensive graphic cards as pretty much any low end video card will do fine. Even an onboard gpu might be a good idea as it will save you money.

Medium – In this group your an average user that likes to do a little bit of everything. In this case look for a gpu that offers a good balance between money and performance. This group starts to care about how much memory the card has. For the average users i would recommend a card thats around 100 plus dollars that has at least 512mb. This will be enough for most people as it will allow you to game on medium/low settings depending on the game. Any people that work with basic graphical programs should fit in this group as well.

Hard –  This is the group thats willing to shed some money to get the best performance. These users include hard core gamers that want the best graphics and high fps (frames per second) while gaming. Also users that run programs that require a strong graphic card fit in this group. These would include people that run auto cad as it demands a strong card to be able to run smooth. For the most part 1gb gpu should be enough.

Depending where you stand ,the 3 groups should give you a basic idea of what graphic card to choose. Things to keep in mind while looking at one is the memory, core clock, and shader clock. Also a few choices to decide on is what version of directx is good for you. The older cards only support directx 9 while the newer ones are capable of supporting directx 10 and 11. Therefore it all depends on what the card is going to be used for.
