Nvidia B300

Q: How much does the B300 cost per hour?

As of September 8, 2026, the median on-demand price is $8.18 per GPU per hour across 10 providers with a priced on-demand config. On-demand: 33 configs, median $8.18, cheapest $6.50 Reserved: 70 configs, median $5.70, cheapest $4.25 Spot: 18 configs, median $5.85, cheapest $4.30 Custom contract: 10 configs, cheapest $4.49 No median for custom-contract: we only show this when at least 3 providers list the GPU on that billing type. Custom-contract pricing is negotiated per deal and usually not published.

Q: Who has the cheapest B300?

As of September 8, 2026, the lowest listed on-demand price for the B300 is $6.50 per GPU per hour from Bentaus, though we haven't verified current stock. Cheapest verified in stock: on-demand $8.50 from Lium.

Q: How much does the B300 cost per month?

As of September 8, 2026, at 720 hours per month, one B300 costs an estimated $5,890 at the median on-demand price. Cheapest verified in stock: $6,120 per month on-demand, $3,715 reserved, $4,212 spot.

Q: Where can I rent a B300?

GetDeploying currently tracks B300 configs from 30 providers. Lium and Vast.ai have verified in-stock on-demand configs. See the full price comparison above for every provider and config.

Q: Are B300 prices going up or down?

As of September 8, 2026, the median on-demand price has been flat over the past 90 days, at about $8.18 per GPU per hour.

Q: How many B300 GPUs do I need?

One B300 runs models up to roughly 460B parameters at 4-bit quantization or 125B at 16-bit, assuming a 32K context. Larger models run across multiple GPUs: the model table above shows the estimated memory and GPU count for popular open-weight LLMs.

Q: Why choose the B300?

288GB of HBM3e and 1,800 GB/s of NVLink, a capacity matched in the Blackwell line only by the GB300. Holds 200B-parameter models on a single GPU without quantization.

Q: When is the B300 not a good fit?

The highest cost tier in the Blackwell lineup. For most workloads, the B200 or H100 offers sufficient memory at lower cost.

Blackwell Ultra GPU for training and serving the largest foundation models.

How this list works

The two views

By provider shows one card per company, placed where its best offer ranked. By configuration lists every offer.

Order

What you can rent comes first: in stock, then waitlist, then not reported, then out of stock. Priced offers rank ahead of quote-only, and on-demand ahead of other billing types.

Within a group, five factors set the order:

Location: datacenter proximity, blended with provider HQ.
Price: hourly price, per GPU and in total.
Billing type: reserved ahead of spot, spot ahead of quote-only.
Specs: more VRAM, vCPUs and RAM.
Provider diversity: a provider's repeat rows rank slightly lower, so one company can't take all the top spots.

Search

We match the provider, its country, GPU model, form factor, billing type, availability and instance name. Matching is partial and case-insensitive. Everyday words work too, so "interruptible" finds spot and "sold out" finds out of stock.

Transparency and funding

Ads and sponsors: Paid placements sit at the top of the list and are always labeled as sponsored content. Sponsorship never influences the organic ranking itself.
Affiliates: Affiliate links are marked. We may earn a commission if you click them, but commissions never affect the order.
Prices: Shown in USD, converted at daily reference rates where a provider publishes in another currency. A month means 720 hours. How we estimate costs.

What size AI models can the B300 run?

One B300 has up to 288 GB of VRAM. In practice, that's enough memory for roughly 460B parameters at 4-bit or 125B at 16-bit, assuming a 32K context. Below are some open-weight LLMs, with the estimated memory and GPUs each one needs.

Estimates based on the median on-demand rate. Memory is weights plus FP8 KV cache at 32K context per request (FP16/BF16 in the 16-bit column). GPU counts assume 90% of advertised VRAM is usable. No guarantee of runtime support, usable performance, or that a matching quantized build exists. How we estimate costs.

Frequently Asked Questions

How much does the B300 cost per hour?

As of September 8, 2026, the median on-demand price is $8.18 per GPU per hour across 10 providers with a priced on-demand config.

Billing type	Configs	Median / GPU / hr	Cheapest
On-demand	33	$8.18	$6.50
Reserved	70	$5.70	$4.25
Spot	18	$5.85	$4.30
Custom contract	10		$4.49

No median for custom-contract: we only show this when at least 3 providers list the GPU on that billing type. Custom-contract pricing is negotiated per deal and usually not published.

Who has the cheapest B300?

As of September 8, 2026, the lowest listed on-demand price for the B300 is $6.50 per GPU per hour from Bentaus, though we haven't verified current stock. Cheapest verified in stock: on-demand $8.50 from Lium.

How much does the B300 cost per month?

As of September 8, 2026, at 720 hours per month, one B300 costs an estimated $5,890 at the median on-demand price. Cheapest verified in stock: $6,120 per month on-demand, $3,715 reserved, $4,212 spot.

Where can I rent a B300?

GetDeploying currently tracks B300 configs from 30 providers. Lium and Vast.ai have verified in-stock on-demand configs. See the full price comparison above for every provider and config.

Are B300 prices going up or down?

As of September 8, 2026, the median on-demand price has been flat over the past 90 days, at about $8.18 per GPU per hour.

How many B300 GPUs do I need?

One B300 runs models up to roughly 460B parameters at 4-bit quantization or 125B at 16-bit, assuming a 32K context. Larger models run across multiple GPUs: the model table above shows the estimated memory and GPU count for popular open-weight LLMs.
