The dedicated GPU industry is still going through hard times due to chipsets losing the interest of cryptourrency miners, which was confirmed by the latest statistics from the analytics company Jon Peddie Research. In Q4 2018, end customers received 10.7% less GPUs than in the previous quarter, while the comparison with the same period last year was even more unfavorable, as the result was 40.2% worse.
As you can see, Nvidia was less affected by the crisis - in the last three months of last year GeForce family chips accounted for 81.2% of total sales, which is an increase of almost 7 percentage points compared to the third quarter of 2018. Of course, the same amount of money was lost by AMD, which boasts a market share of 18.8%.
The last few months certainly werent kind to AMD - by the end of 2017, the company was able to boast 33.7% sales, so AMD's market share in the discrete GPU market had dropped by nearly 50% within twelve months. The situation hasn't changed with the recent release of Radeon VII and Radeon RX 590, and the nearest chance to reverse the negative trend seems to be the debut of GPUs based on AMD Navi technology. However, it is not known when this will happen - their release is expected in a few months at the earliest.
