For context, AMD's quarterly revenue is ~5B and Intel's is ~$20B.
AMD's quarterly net income is ~$1B and Intel's is ~$4.5B.
I'm surprised that AMD is valued higher, despite their revenue and profits being so much smaller. The financial markets are in essence betting that AMD will be able to achieve revenue/profit parity with Intel, despite the huge lead Intel currently has. It will be very interesting to see if that comes to pass.
I remember the days when AMD seemed to be on the verge of bankruptcy, and there was talk of Intel simply buying AMD since it was so cheap. Presumably that didn't happen because Intel feared anti-trust laws if it purchased its main/only competitor. Kudos to AMD for the turnaround - this competition is sure to be benefit the wider industry.
