The German webshop reports the share of AMD CPU sales via its store increased from 28 percent in March 2017 to a whopping 56 percent by the end of August. The sales figures suggest AMD may be doing quite well in the DIY processor market, but it's perhaps still a bit early to draw firm conclusions from this. Germany has typically been a more AMD-minded country so these figures don't tell the full tale about how AMD is doing in the global PC market.
The strong volume of Ryzen sales could also be caused by pent-up demand, although the figures provided by the webshop illustrate the higher AMD marketshare was the result of a combination of both higher Ryzen sales as well as lower Intel Core sales. The coming months and AMD's financial results will provide a more nuanced picture. So far it seems pretty encouraging for AMD.
