While PC sales are expected to fall, analyst outfit Bedford claims that chipmakers AMD and Nvidia will probably be OK. The report says that while PC sales are important to AMD and Nvidia's top lines, both companies have made significant efforts to diversify their product lines towards new revenue drivers.

The Bedford Report commented how earlier this month the Semiconductor Industry Association (SIA) announced that global chip sales fell 1.5 percent in June from a month earlier due to weak consumer demand offset growth in corporate-replacement purchases, smartphone demand and increased spending on information-technology infrastructure.

But the report said that Nvidia is one of the top five sellers of smartphone applications processors. The company's Tegra line of chips is proving popular with Android tablet and smartphone makers. Most Android 3.x Honeycomb tablets that are available at the moment have Tegra 2 processors.

AMD has begun to concentrate on tablets. AMD's Z-series chips, which are based on the Fusion architecture, will deliver a full PC in tablets, the report said.
