With the exception of Asustek Computer, most Taiwan makers of graphics cards recorded declining shipments in January, partly due to weak demand as well as a shortfall in the supply of graphics chips from ATI Technologies and Nvidia, according to sources at the makers.

Asustek's shipments of graphics cards grew 3.4% sequentially to 880,000 units in January, company sources said.

Tul and Leadtek Research, however, saw their shipments decline 25% and 50%, respectively, in January, after both had posted record-high shipments in December.
