Traditionally, this is a time of year when most people are preoccupied with holidays, so very little is announced or launched in the IT industry. Not so this year. While ATI's Radeon X1950 XTX may not be a revolution, it does promise another step towards single-chip graphics cards.

This article appears in the November 06 issue of PC Advisor, onsale now in all good newsagents.

No company has done more than ATI to ensure that graphics card memory goes from strength to strength – the X1950 XTX plays host to 512MB of GDDR4 memory. The beauty of GDDR4 is it cuts the amount of power used, allowing memory to be run at higher clock speeds. Does this work in practice? Click here for our review of Sapphire's version of the chip.

Intel has received acclaim for its latest family of desktop processors, the Core 2 Duo. However, its attempt to gain a stranglehold over the CPU market sees it revamping its line-up of mobile chips. Although these consist of Core 2 Duo processors, the industry is happier referring to their codename, Merom.

Do Merom chips prolong battery power while hitting new heights of performance? Well, we've got a couple of Merom-enhanced laptops from Hi-Grade and Rock, so you can see how they fared.

And it's not just Intel and ATI that have been busy. Canon has launched its 2007 product range and we've had an early look at a couple of its printing products. We've seen the latest addition to Sony's 19in flat-panel range – the first graphics card to feature the HDMI interface – and a digital radio that you can customise. If this summer has been anything to go by, Christmas promises to be packed with more launches and technological marvels than ever. Enjoy.
