H100 vs MI300X rental price and specs
H100 and MI300X side by side: the same provider-class price for each, price per dense PFLOP-hour at one precision at a time, and their spec sheets. Every price carries its venues and observation dates.
Rental price by provider class, US$ per GPU-hour
Each row compares one class aggregate with the same aggregate for the other chip — never one class or billing model with another. The on-demand rows use provider list prices only; the marketplace row is variable-availability asks.

Price per dense PFLOP-hour, one precision at a time
Each chip's cheapest specialist on-demand list price divided by its dense (non-sparse) tensor rate at the same precision. A precision a spec sheet does not list is left blank, never converted from another.
