AMD pulled one off this time. Congrats to them.
However, if we take a look at history, we also know what Intel will soon be doing. Years ago, AMD got it right with the Athlon. Intel had to scramble.
When Intel got it together, their marketing department went nuts, their R&D went nuts, and AMD ended up with less than 10 percent of the market before they came up with something good again.
AMD isn't stupid either, now they are going for a broader market. Not just with PC CPU's, but now also server platforms. Good steps if they want to stay competitive. AMD still has obstacles in their way. Like....Intel.
Intel STILL has a massive R&D budget, that will top 15 BILLION...yes....with a B...in 2018 (Roughly 21x what AMD's total worth is). They also have a massive marketing team, that is VERY good at what they do. So, Intel has exactly the same playbook and resources to beat AMD back to almost extinction, as they did 15 years ago.
I would be willing to wager that you hear a lot more Intel commercials on tv in the next few years. Have you noticed that Intel commercials have almost gone silent in the last few years, compared to before?
