Horrifyingly bad decisions with architecture - Bulldozer completely obliterated AMD&#x27;s desktop market. Intel doesn&#x27;t even look at AMD&#x27;s opportunities when deciding on engineer salaries anymore.<p>They&#x27;re trying to make a comeback with Zen, but one of the biggest issues with development is that you learn from the successes and failures of your previous product. If your previous product sucked, you&#x27;re under an enormous amount of pressure to fix those problems before you even get started on your next generation. Otherwise, those problems will persist, <i>and</i> you&#x27;ll get new problems as well.<p>They&#x27;ve stayed relevant in the GPU market, though.
