To expand on what others said, there has been tons of corporate dysfunction at Intel.

Some hardware efforts have gone pretty well, and had decent long-term trajectories but were sabotaged by direction changes or early cuts from up high. There seems to be some corporate "game of thrones" going on between branches too, and a lot of redundancy on the software dev side.

AMD has a similar issue actually, and it's starting to bite, especially on the GPU side.
