B300 SXM 262GB Rental Guide
Renting the B300 SXM 262GB makes sense when your workload requires 262GB of HBM3e memory and 2800 TFLOPS of FP16 compute. The most common use cases are Frontier LLM training, Massive multi-GPU clusters, Trillion-parameter models. Before committing to a rental, verify that your model and batch size fit within 262GB — a 70B parameter model requires approximately 140GB at FP16, which would require two B300 SXM 262GB instances with tensor parallelism.
For fault-tolerant batch workloads — preprocessing, offline inference, or training with checkpointing — spot instances typically save 40–70% vs on-demand rates. The B300 SXM 262GB's 262GB VRAM makes it well-suited for long-running batch jobs where interruption recovery is manageable. On-demand instances give you full control with no commitment — ideal for development, short experiments, and workloads with unpredictable duration. Most providers bill per second or per minute, so short jobs are not penalized by hourly minimums.
For sustained production inference serving, reserved instances (1–3 month commitments) typically offer 20–35% savings vs on-demand. The B300 SXM 262GB's high throughput makes it cost-effective for high-volume inference where per-token cost matters. When comparing providers, look beyond the headline hourly rate: check region availability (latency matters for interactive inference), spot interruption frequency, and whether the provider offers per-second billing. Use the GPU cost calculator to model total cost across different billing models and utilization rates before choosing a provider.
Frequently Asked Questions
How much does it cost to rent a B300 SXM 262GB?
B300 SXM 262GB on-demand rental prices vary by provider and region. On-demand rates typically range based on availability and provider margins — use the comparison table above to see current live rates across all providers. Spot instances are generally 40–70% cheaper than on-demand but can be interrupted. Monthly cost estimates (hourly rate × 730 hours) are shown in the table for sustained workloads.
Which cloud provider has the cheapest B300 SXM 262GB?
The cheapest B300 SXM 262GB provider changes as providers update their pricing. The comparison table above shows live rates sorted by price, so the cheapest option is always at the top. Factors beyond headline price include region (latency to your users), availability (high/medium/low), and billing granularity (per-second vs per-hour minimums).
What can I run on a B300 SXM 262GB?
With 262GB of HBM3e, the B300 SXM 262GB can run LLM models up to approximately 131B parameters at FP16, 262B at INT8, or 524B at INT4/GGUF quantization. Common workloads include: Frontier LLM training, Massive multi-GPU clusters, Trillion-parameter models. SXM6 form factor Blackwell Ultra. 262GB HBM3e — higher memory than B200. Successor to B200 with increased VRAM capacity for the largest models.
Should I use on-demand or spot pricing for B300 SXM 262GB?
Spot instances save 40–70% vs on-demand but can be interrupted when the provider needs capacity back. Use spot for: batch inference jobs, training runs with checkpointing, preprocessing pipelines, and any workload that can tolerate interruption and restart. Use on-demand for: production inference serving, interactive workloads, and jobs that cannot be interrupted. Most providers bill per second, so short on-demand jobs are not penalized by hourly minimums.
How does the B300 SXM 262GB compare to the H100 for cloud rental?
The H100 80GB delivers 1,979 TFLOPS FP16 with 3,350 GB/s HBM3 bandwidth, compared to the B300 SXM 262GB's 2800 TFLOPS FP16 and 8000 GB/s bandwidth. The H100 is significantly more expensive — typically $2.50–$5.00/hr vs lower rates for the B300 SXM 262GB. For workloads that fit within 262GB and don't require FP8 precision, the B300 SXM 262GB often delivers better cost-per-token than the H100.
What is the memory bandwidth of the B300 SXM 262GB and why does it matter?
The B300 SXM 262GB has 8000 GB/s of memory bandwidth. For LLM inference, memory bandwidth is often more important than raw TFLOPS — each autoregressive token generation reads the full model weight matrix from VRAM, so bandwidth directly determines tokens-per-second throughput. Higher bandwidth means faster inference for the same model at the same batch size. For batch inference (processing many requests simultaneously), compute throughput becomes more important.
Can I use the B300 SXM 262GB for Stable Diffusion or image generation?
Yes — the B300 SXM 262GB is well-suited for Stable Diffusion and image generation workloads. Image generation is primarily FP32 and FP16 compute-bound, and the B300 SXM 262GB's 60 TFLOPS FP32 throughput determines images-per-second. The 262GB VRAM fits SDXL (requires ~6GB) and most ControlNet pipelines. For high-throughput image generation at scale, compare cost-per-image across providers using the GPU cost calculator.
