The research firm said PC unit shipments are on pace to grow 12.7 percent to total 206.6 million in 2005 and will increase 10.5 percent to hit 228.29 million in 2006.
The statistics underscore the pricing pressure that's squeezing PC makers even as demand for their computers continues to increase.
Prices for a basic desktop setup have hit rock bottom. CompUSA, for example, advertised a special this weekend for a $199.99 Hewlett-Packard Pavilion desktop with a monitor after about $370 in rebates. Dell has been offering entry-level Dimension desktop computer bundles for $299 for some time andare becoming more commonplace.
Price cuts are ordinary in the PC world, but the recent price wars have forced vendors to look for even the most minute cost-cutting measures, according to the Gartner report.
"We're reaching a point where PC makers are testing how low the markets can go," said analyst George Shiffler, co-author of Gartner's quarterly global PC forecast for 2005 and 2006.
To pick up the slack, many PC makers are cutting back on computer memory, offering fewer features and installing smaller hard disk drives as a way to cut prices and attract customers, Shiffler said.
Unit growth with no revenue growth has been a tricky phenomenon for a while. Last year, Gartner similarly reported that unit shipments rose about 12 percent, but prices went down about the same percentage.
"Companies are trying to move people to mobile computers, but they are also asking themselves are enough people still interested in desktops to make it a profitable business," Shiffler said.
The HP Pavilion comes with 256MB of RAM, a CD-ROM and a 40GB hard drive, hardly the configuration consumers would want if they were thinking of burning a CD, watching a DVD or using the PC for video editing or high-end PC gaming. But the low-ball pricing helps get customers in the door, Shiffler said, allowing customers all sorts of opportunities to upgrade to an $800 or $900 machine.
Notebooks are seeing cuts, too. Recently, , HP and trotted out , a new low-water mark for major PC makers. In the past, only second-tier manufacturers offered laptops at this price, and even then they didn't include Windows.
Consumers' desire to shift from desktops to notebooks is also propelling a replacement cycle, according to Gartner. That's good news for many manufacturers' bottom line: Not only do notebooks typically sell for more than desktops, they typically also are replaced faster by consumers.
In all, 46.6 million desktops, notebooks and servers containing Intel, Advanced Micro Devices or PowerPC chips left factories between April and June of this year, according to Gartner's statistics.
Financialand have also caught the eye of analysts who say PC makers may have reached their limit on the desktop front.
Shiffler said IBM's sale of its legendary PC business to Lenovo may just be the tip of the iceberg to the massive shift in the desktop PC market and recounted Gartner's prediction that three of the top 10 PC manufacturers.
Japan's NEC may be the next in line. The PC maker is reportedly considering selling off its Packard Bell home computer division in a deal which could be worth around $180 million, according to a report in the Scotsman. A representative with NEC declined to comment on the news.
