Lesson & Term of the Day

Today's lesson

H100 vs H200 vs B200: price, memory, and performance

How NVIDIA accelerator generations compare on workload fit, current GPU-hour pricing, memory, and availability. Why it matters today: Today's lesson connects the AI Compute 101 track to the compute market readers are watching.

Term of the Day

Queue time

Queue time is the delay before a compute job actually starts running. In constrained AI environments, jobs may wait for available GPUs, cluster slots, storage, or scheduling priority. Queue time is a hidden cost because teams lose speed even if the hourly price looks acceptable.
