alt Hacker NewsRegarding the critique on the title: perhaps an analogy can be made to propeller cavitation on ships. Water influx rate, propeller design and operational parameters all influence the detrimental effect of water bubbles forming — deteriorating the system's efficiency.
The GPU would be the propeller, the influx is the work, and the operational parameters is what this article's about.
I'm disappointed with the commentary here. "GPU bubble" is an industry standard term, and literally how I would describe this to my colleagues in the industry. Look for example at the second slide here https://media.steampowered.com/apps/valve/2015/Alex_Vlachos_...
