GPU MODELS / ALTERNATIVES TO H100 SXM
Alternatives to the H100 SXM
The H100 SXM is the chip the current generation of frontier models was trained on, and the benchmark every other datacenter GPU is priced against. Its Transformer Engine with FP8 roughly doubles effective LLM throughput over Ampere, and 900 GB/s NVLink keeps 8-way and larger clusters coherent. Two generations old now, but still the default answer for serious training.
People usually compare the H100 SXM against A100 80GB SXM, H200 SXM, B200. Prices below are live on-demand published rates from the panel.

WHEN EACH ALTERNATIVE WINS
A100 80GB SXM
H100 delivers ~3x the dense FP16 and 6x with FP8, at typically 2-3x the hourly rate. Pre-training pays for the premium; fine-tuning often does not.
H200 SXM
Same compute, 76% more memory (141 GB) and 43% more bandwidth. For inference of large or long-context models the H200 is strictly better; for training, whichever is cheaper per hour on the panel.
B200
Blackwell roughly doubles dense FP16 and adds FP4, with 192 GB at 8 TB/s. Scarce and priced accordingly - the H100 remains the value pick for most training.
H100 SXM ALTERNATIVES - FAQ
What is the best alternative to the H100 SXM?
It depends on the workload. A100 80GB SXM: The A100 80GB was the standard large-model training chip of 2021-2023 and still anchors an enormous installed base. H200 SXM: The H200 is an H100 with the memory subsystem rebuilt: 141 GB of HBM3e at 4.8 TB/s versus 80 GB at 3.35. B200: The B200 is Blackwell's datacenter flagship: roughly 2.3x the H100's dense compute, a new FP4 precision that doubles effective inference throughput, 192 GB at 8 TB/s, and NVLink 5 at 1.8 TB/s. Live rates for each are in the table above.
Why look for H100 SXM alternatives?
Inference of models that fit on one 48 GB card - the premium over L40S buys nothing there.
How much does the H100 SXM cost compared to its alternatives?
Each alternative's current cheapest published rate is listed in the table above; figures recompute hourly from provider-published prices.
