Demand outstrips supply by such a wide margin it doesn’t matter one bit how they compare.
The cheapest 8x A100 (80GB) on the list is LambdaLabs @ $12/hour on demand, and I’ve only once seen any capacity become available in three months of using it. AWS last I checked was $40/hr on demand or $25/hr with 1 year reserve, which costs more than a whole 8xA100 hyperplane from Lambda.
