According to Jon Peddie Research, GPU shipments in Q3 2018 are down 2.2% compared to Q3 2017. But that decline is largely due to a 16% drop in desktop graphics shipments, as notebook graphics shipments actually increased by 7% year on year. Both AMD and Nvidia lost marketshare to Intel compared to last quarter, and the percentage of PCs that shipped with discrete GPUs dropped to to 31.61%. Thanks to VentureBeat for spotting the report. "The effect of crypto-mining on desktop discrete GPU sales is over, leaving AMD and Nvidia with an oversupply in the channel and impacting shipment levels," said Dr. Jon Peddie, President of JPR. "The U.S. tax increase on products from China has had a small effect which may worsen in Q4. The drop in the U.S. stock market has caused consumers and enterprise to hold off on purchases. All of that has contributed to the slow sell-off of inventory in the channel, which has reduced demand to the suppliers."
