Is the MI300X cheaper than the H100 to rent?
The MI300X and H100 rent in a similar range, and which is cheaper depends on the provider and day rather than a fixed rule. The cheapest verified H100 in our index is $1.99/hr. The MI300X's real advantage is memory: at 192GB it more than doubles the H100's 80GB, so it can hold much larger models on a single card. The table below shows the current verified MI300X rates so you can compare them against the H100 directly.
The two cards target overlapping work from different angles. The H100 is NVIDIA's Hopper datacenter GPU with the most mature software stack, so almost every framework and optimization targets it first. The MI300X is AMD's answer, and its headline feature is 192GB of high-bandwidth memory, which lets a single card serve models that would need two or more H100s.
On price per hour the two are often close, but price per unit of work depends on your model. If your workload fits in 80GB, the H100 is usually the safer, better-supported choice. If you need more than 80GB on one card, the MI300X can be cheaper overall because it avoids a multi-GPU node and its interconnect overhead.
Software maturity is the other factor. NVIDIA's CUDA ecosystem is deeper, while AMD's ROCm has improved a lot but can still require more setup for some frameworks. Weigh that against the memory advantage for your specific model. The table below lists the current MI300X rates, sorted by price and rebuilt from the daily snapshot.
