How we sort results
Default ranking
Our algorithm weighs five factors to find the most relevant matches for you:
- Price: We blend total hourly price with price-per-GPU to balance affordability and value.
- Specs: We favor offers with higher CPU, RAM, and GPU Memory.
- Billing: We favor on-demand billing for simplicity and flexibility over spot instances, reservations, and custom quotes.
- Location: We blend both datacenter proximity and provider HQ location. Datacenter location matters for latency, while HQ location matters for compliance and support.
- Provider diversity: Each time a provider appears in the list, their subsequent offerings are ranked a little lower, so one provider's offerings don't crowd out the top positions.
Sorting and filtering
Click any column header to sort by that column. Use the filters above the table to narrow results by billing type, GPU count, vCPUs, or RAM. Custom sorting resets the default relevance ranking.
Transparency and funding
Ads and sponsors: Any paid placements are fixed at the top and clearly labeled as sponsored content.
Affiliates: Any affiliate links will be indicated to you as well. We may earn a commission if you click them, but this never influences the ranking order.

Frequently Asked Questions
Why choose the B100?
192GB HBM3e with Blackwell architecture FP4 Tensor Cores. 1800 GB/s NVLink for massive multi-GPU scaling. Significant inference throughput improvement over H100 with FP4 precision.
When is the B100 not a good fit?
New generation with limited provider availability. High cost per hour. For inference on models under 70B or workloads that don't benefit from FP4, the H100 or L40S is more cost-effective.
What size AI models can the B100 run?
With 192GB of VRAM, the B100 can usually run 70B-class models with headroom, and may handle much larger models in 4-bit quantized form depending on runtime overhead, KV cache, and context length.
How much VRAM does the B100 have?
The B100 has 192GB of VRAM. Multi-GPU setups increase total memory, but that memory is not automatically pooled across GPUs.
What is the B100's memory bandwidth?
The B100 has 8,000 GB/s of memory bandwidth. Higher bandwidth helps with faster data transfer between GPU memory and compute cores.
What data types does the B100 support?
The B100 supports 9 precision formats. Training: BF16, FP16, TF32, FP32. Inference: FP4, FP6, FP8, INT8. Scientific: FP64.
Does the B100 support NVLink?
Yes. The B100 supports NVLink with 1800 GB/s of bidirectional bandwidth. This helps accelerate multi-GPU communication.
Which cloud providers offer the B100?
The B100 is available from 1 cloud provider: CUDO Compute.
Can I rent the B100 in the cloud?
Yes. We currently track 1 B100 listings across 1 cloud providers:
