Power efficiency of AlphaGo’s victory

So another decade maybe before it achieves power parity?

Lee Sedol used about 20 Watts of power to operate. By contrast, AlphaGo runs on a whopping 1920 CPUs and another 280 GPUs for an estimated power consumption of approximately 1 MW (200 W per CPU and 200 W per GPU). That’s 50,000 times as much power as the amount of power that Lee Sedol’s brain uses and the two are not quite evenly matched but it is close enough to use for comparison.

What if: Yoda Power

19kW, in case you ever wondered how much power Master Yoda had:

But with world electricity consumption pushing 2 terawatts, it would take a hundred million Yodas to meet our demands. All things considered, switching to Yoda Power probably isn’t worth the trouble—though it would definitely be green.
