Summery - Not in the habit of releasing one graphics card at a time these days, ATI have released another series of cards going by the name of X1900. The core is named the R580 and as you imagine it takes another step forward from the X1800 series. In the X1900 we have the X1900 XT, X1900 XTX, X1900 Crossfire master edition and the X1900 All-in-Wonder. So plenty to choose from but all aimed at the top end of the market, the enthusiasts or indeed the power gamer.

X1900 All In Wonder

This is the first time that ATI have released an All-In-Wonder card at the same time as the rest of the series. Normally the AIW is an after thought and an addition to a series. This time however ATI have come in with all guns blazing and given the consumer maximum choice from the off. The ALL-In Wonder graphics card offers all the features of the other X1900 cards (even if at a lower speed) and also throws into the mix TV and DVD features. This is where the X1900 All-in-Wonder comes to life. With this graphics card you can virtually do anything that involves TV and Video. The X1900 All-in-Wonder will play live TV, record TV, Decode DVD's, edit video files plus it has a number of input and output capabilities in order to import and export video to other devices. If you connect up everything that you can into the All in Wonder you may find that it doubles the amount of cables that your PC already has.

To Take control of all the TV and video features that the X1900 All-In-Wonder offers, ATI supplies you with the Remote Wonder Plus. A rather extravagant sounding name for a remote control, but given its due, its a very useful piece of kit, which you don't always get with TV cards. The remote uses an RF signal instead of the traditional Infra red signal which gives you a little more range and also means you don't have to point the remote directly at the receiver. This means you can hide the receiver out of the way somewhere and not have to have it cluttering up your desktop. The receiver simply plugs into a USB port and once the software is setup you are ready to roll.

The X1900 All-in-Wonder does come with a couple of very useful software titles (as well as the comprehensive software suite for all the X1900 All-in-Wonder from ATI). These are Adobe Premier elements 2.0 and Adobe Photoshop Elements 4.0. These two pieces of software really raise the value of the X1900 All-In-Wonder while also allowing you to jump straight in to professional photo and video editing on your PC.

Adaptive Anti-Aliasing

New technology? apparently not but it is new to a lot of us. Adaptive anti aliasing was introduced by Nvidia in the G70 core, but checking this link on Adaptive Anti-Aliasing it shows you how to enable it in ATI cards from Radeon 9500 upwards. Now onto what Adaptive Anti-Aliasing actual does.

The previous versions of Anti-Aliasing being Super-Sampling and Multi-Sampling could not handle everything that was needed to anti-alias a whole screen. Super-Sampling was simply too slow and expensive to implement, multi-sampling now the common method also had a problem. It worked by detecting edges of objects to reduce the amount of work needed to be done. One thing it couldn't do is anti-alias Alpha textures. I hear cries of what on earth are Alpha textures? to to put your mind at ease, an alpha texture is like a normal texture except it uses the alpha channel to give the texture transparent qualities, used for fences or shrubbery etc. With adaptive Anti-Aliasing a new algorithm has been written to allow the anti-aliasing of alpha textures. The algorithm searches out Alpha textures and uses Supersampling on this part of the screen to give a full AA effect. More info on Anti-Aliasing techniques here

Crossfire

Crossfire is ATI solution to a multi graphics card system setup. Nvidia has used a standard SLI solution to accommodate multi GPU's, ATI's solution however does have its differences, some advantages and some disadvantages. ATI's crossfire system does not need the exact same card as the second card in the system like SLI. However the crossfire system does require that the first graphics card is a Crossfire master card which are marketed as such. Also Crossfire requires a specific motherboard which is crossfire enabled, while Nvidia's SLI solution simply needs a PCI express SLI motherboard, with the available slots. Read more on Crossfire

PCI Express

Like the vast majority of graphics cards released now. the Radeon X1300 uses the PCI Express bus and not AGP (AGP available with an extra hardware bridge chip), check your motherboard before purchasing one of these cards. Chances are you will have a PCI express slot if your motherboard is under 2 years old. Refer to your motherboard manual for details.
