Could you elaborate on how is this relevant to the main point of the article, which is that Nvidia has increased and AMD lost market share?
Q1 '23 to Q1 '24 AMD had the same market share: 12%.
Q1 '23 to Q1 '24 Nvidia increased their market share from 84 to 88%, by apparently taking Intel's 4%.
YoY is the most interesting stat as that shows how a company's products do at a similar time in the market, subsequent quarters are less informative as you are courting buyers in a different frame of mind. So AMD's expansion from Q1 to Q4 is not particularly informative just like their subsequent contraction the following quarter.
