Summery - ATI have gone for a different approach with its new series of graphics cards. The X1000 series of cards have been released on an almost simultaneous basis. The X1300, X1600 and X1800 are all released within 6 weeks of each other to the retail market. Not to mention the variations of each of these cards. ATI have release an entirely new family of Cards. First we have the budget series in the family the X1300


The X1300 graphics series comes in three variants. They are all classed as budget cards for the market and are all relatively cheap compared with the others in the X1000 series. The three cards are the X1300 Pro, X1300 and the X1300 Hyper Memory. The Pro version is the fastest, its worth pointing this out as previously in other graphics cards the Pro has been a lesser card than say an XT version. The X1300 standard is just that, the standard edition. Then we have the X1300 Hyper Memory. This is something we haven't seen in a while. Hyper memory sounds great, but the deal with it is that it only comes with 32Mb of memory on the card. You then have the option to use up to 128Mb of your system memory for the X1300 Hyper Memory to use. This of course has a negative effect on your system. Looking on the flip side of the coin though, it is a very cheap graphics card and if your not looking for a top of the range card, this could well be worth looking at for the price alone. Bear in mind it still has the new architecture and actually has a faster core than the standard X1300.

X1000 Series Card comparison

To compare the different graphics cards in the series wave have the basic specs for the top cards in each range. Its not a sure fire way to pick a card but it does show you what extra speed the extra money will buy you. You can then decide for yourself which is the best buy.

ATI Radeon X1300

The Radeon X1300 is aimed at the budget end of the market, but that doesn't mean that its not a respectable graphics card. A 256Mb card with a 600Mhz clock and 800Mhz memory clock is a nice package for a bottom end card (pro version). So apart from the speed which is lower than the other cards in the series what other differences are there with the X1300?

Well pipelines are always a big factor in gaming performance at higher resolutions. More pipelines more pixels can be processed per second. The X1300 only has 1/3 of the pipelines than that of the X1600 and 1/4 of the X1800. The X1300 sits with 4 pixel pipelines. Not enough to play games with high resolutions but good enough with the speed it has to still keep casual gamers happy. Like everything these days though, quantity and speed are not the be all and end all. In today's market efficiency plays a big part in technologies real world performance. Even though you will still see ATI and Nvidia bang on about peak fill rates from time to time, it is losing its importance the overall performance of a graphics card. Remember that the X1300 is based on the same technologies as the X1600 and the X1800 so although it may not be as fast its still a next generation card with all the features. The X1300 is also crossfire enabled, read more below


Crossfire is ATI solution to SLI technology. This allows you to combine two graphics cards together and use them simultaneously to increase the performance of your graphics subsystem by almost double. This is proving a very popular way of upgrading, because you don't have to buy both graphics cards together. Upgrade to one now and buy another later when you need to upgrade again. Its the cheapest way as the graphics card prices will have come down. Certain requirements need to be met with crossfire but less so with the X1300 as it doesn't need a master card the X1300 can use the PCI express bus to link together providing a crossfire motherboard is used.

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.
