GPU MODELS / ALTERNATIVES TO GB300
Alternatives to the GB300
GB300 is the Grace-Blackwell Ultra superchip: B300-class GPUs paired with Grace CPUs, sold as NVL72 racks rather than cards. Cloud listings for GB300 mean rack-scale capacity - 288 GB per GPU and the fastest interconnect shipping - aimed at frontier-scale training and reasoning-model serving.
People usually compare the GB300 against B200, H100 SXM. Prices below are live on-demand published rates from the panel.
LOADING LIVE DATA...
| Alternative | Memory | Bandwidth | Cheapest live rate | Head to head |
|---|---|---|---|---|
| B200 | 192 GB HBM3e | 8 TB/s | - | GB300 vs B200 |
| H100 SXM | 80 GB HBM3 | 3.35 TB/s | - | GB300 vs H100 SXM |
WHEN EACH ALTERNATIVE WINS
B200
The B200 is the mainstream Blackwell; GB300 adds memory and FP4 throughput for reasoning-class models. For most training the B200 is the practical part.
H100 SXM
Two generations back: a fraction of the throughput and memory, at a fraction of the price. For work that fits in 80 GB, the H100 remains the value choice.
GB300 ALTERNATIVES - FAQ
What is the best alternative to the GB300?
It depends on the workload. 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. 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. Live rates for each are in the table above.
Why look for GB300 alternatives?
Single-model dev work or fine-tuning - an A100 node costs a fraction.
