B200 vs H200: Specs, VRAM & Price
Short answer: pick the B200 when you want the newer Blackwell-generation architecture and it's in stock in your region. Pick the H200 when H200 availability or price is better where you're deploying, and Hopper-generation FP8 already covers your workload.
The B200 has 180 GB of VRAM; the H200 has 141 GB.
You can rent both by the hour, no purchase required. B200 from $9.35/GPU/hr; H200 from $5.05/GPU/hr. The H200 is 46% cheaper at the entry rate.

Which is better for AI: B200 or H200?
Both are FP8-capable, but the B200 is the newer Blackwell-generation part (vs H200's Hopper), with the same lib/tools/gpu-capabilities.ts precision floor (BF16/FP8/INT4 on both), so the real question for most renters is architecture generation and availability, not a documented VRAM or bandwidth number Aquanode can verify for the B200's single-GPU spec. Pick the B200 when you want the newer Blackwell-generation architecture and it's in stock in your region; pick the H200 when H200 availability or price is better where you're deploying, and Hopper-generation FP8 already covers your workload. On price the H200 undercuts the B200 by 46% at the entry rate ($5.05 vs $9.35/GPU/hr). Worth weighing if the deciding factor above isn't a hard requirement for your job.
Decision criteria
| Architecture | Blackwell (B200) vs Hopper (H200), one generation apart. |
| Compute precision | Both support BF16, FP8 and INT4 in hardware (lib/tools/gpu-capabilities.ts), with no precision-support gap between them. |
| VRAM | 180 GB (B200) vs 141 GB (H200), live from current marketplace listings. |
| Availability | 1 region(s) list the B200 vs 3 for the H200 today. |
| Entry price | $9.35/GPU/hr (B200) vs $5.05/GPU/hr (H200). |
Pick the B200 when
- You want the newer Blackwell generation and it's in stock where you need it
- You're evaluating next-gen hardware ahead of a larger commitment
- Your workload benefits from whatever B200 supply is currently priced competitively
Pick the H200 when
- H200 has better availability or pricing in your target region
- Your workload is already validated on Hopper and switching adds risk with no clear upside
- You need the wider H200 availability today
Price-performance
At list rates, 1,000 GPU-hours costs $5,050 on the H200 against $9,350 on the B200. Neither NVIDIA nor Aquanode publishes a workload-normalized $/token or $/epoch figure for this pair, so $/GPU-hour below is the only apples-to-apples number. A faster card can still cost less per finished job even at a higher hourly rate.
B200 vs H200: common questions
Is the B200 or the H200 better for AI?
Short answer: pick the B200 when you want the newer Blackwell-generation architecture and it's in stock in your region. Pick the H200 when H200 availability or price is better where you're deploying, and Hopper-generation FP8 already covers your workload.
Is the B200 or the H200 cheaper to rent?
On Aquanode's live marketplace the B200 starts at $9.35/GPU/hr (median $9.35/GPU/hr) and the H200 starts at $5.05/GPU/hr (median $5.05/GPU/hr). The H200 is the cheaper of the two at the entry rate, by 46%.
What is the difference between the B200 and the H200?
The B200 has 180 GB of VRAM against the H200's 141 GB; the B200 is a Blackwell part and the H200 is Hopper (compute capability 10.0 vs 9.0); both run BF16, FP8, INT4 workloads in hardware. On price, the B200 lists from $9.35/GPU/hr and the H200 from $5.05/GPU/hr.
How widely available are the B200 and the H200?
The B200 is listed in 1 region and the H200 in 3 regions right now.
How much does 1,000 GPU-hours cost on the B200 vs the H200?
At the lowest rates listed today, 1,000 GPU-hours costs $9,350 on the B200 and $5,050 on the H200, a difference of $4,300 for the same runtime. Rates are per GPU per hour and update hourly.
How much VRAM does the B200 have compared to the H200?
The B200 has 180 GB of VRAM; the H200 has 141 GB.
Is the B200 strictly better than the H200?
It's a newer generation, but this page can't responsibly claim a specific VRAM or bandwidth advantage for the B200 without a verified NVIDIA figure to cite, so treat "newer" as directional, not a guaranteed win on every spec. What's certain today: the B200 lists from $9.35/GPU/hr and the H200 from $5.05/GPU/hr on Aquanode, updated every 6 hours.
Does the B200 or the H200 support NVLink?
Yes, both support a multi-GPU interconnect: the B200 has NVLink 5, 1.8 TB/s per GPU and the H200 has NVLink 4, 900 GB/s bidirectional.
How this comparison is calculated
Every price is normalized to a per-GPU hourly rate using the same pipeline as every other pricing surface on Aquanode, and only the cheapest qualifying offer per provider is shown. A dash means that provider does not currently list that GPU.
Architecture, compute capability and supported precisions come from each vendor's published datasheet for that generation, not from the marketplace feed. This page regenerates at most once per hour.
Memory bandwidth, tensor TFLOPS, NVLink/interconnect and max board power are the same verified-from-datasheet figures shown on each model's own B200 page and H200 page, which link the primary vendor source for that model. A dash here means Aquanode hasn't verified that figure from a primary source yet, never a guess.
