Large companies either have a corrupt and criminal conspiracy with Intel (they were recently fined for this again, but for pennies) or it's trivial, because AMD does not have its own factories and cannot sharply increase production at TSMC; there are not enough wholesale quantities of AMD processors at a price that suits large companies. Because every Chinese little thing of the second and third tier, surprisingly, sells its crafts with Zen4 without any problems. The greed of large multinationals and the attempt to squeeze out every cent of profit is obvious. Most likely, Intel secretly sponsors (i.e., really sharply reduces prices) laptop manufacturers in violation of antitrust practices, and AMD itself has lost interest in the laptop SoC market, turning its attention entirely to game consoles and server series. Therefore, one cannot expect equality in the series; the real ratio of availability and sales of models based on Intel and AMD is more than 5:1 in favor of Intel and that says it all. When there is no choice on the shelves, you will still buy Intel...
