Researchers and engineers can now get their hands on the first NVIDIA Blackwell GPU, the B200. With 192 GB of ultra-fast HBM3e and a second-generation Transformer Engine that introduces FP4 arithmetic, a single card delivers up to 20 petaFLOPS of sparse-FP4 AI compute.
Blackwell B200 specs & performance
The B200 represents a massive leap in GPU capabilities: built on TSMC’s 4NP process, it packs 208 billion transistors across a dual-die design, enabling both the new FP4 Tensor Cores and an on-package NVSwitch.
- Process: TSMC 4NP with 208 billion transistors (dual-die)
- Memory: 192 GB HBM3e (cloud consoles expose 180 GB usable) — 2.4x H100 capacity
- Bandwidth: 8 TB/s memory bandwidth, doubling Hopper’s throughput
- Peak compute: 20 PFLOPS FP4 with 2:1 sparsity — ~5x H100 inference throughput
- Interconnect: NVLink 5 at 1.8 TB/s bidirectional, removing PCIe bottlenecks
This huge transistor budget allows you to fit models that would require complex parallelism on H100s, while delivering inference throughput that makes real-time AI applications viable.
NVIDIA B200 cloud pricing
Here’s per-GPU pricing for B200s across major providers, from most to least flexible purchase options (July 2025):
| Provider & SKU | Serverless | Spot | On‑demand | Capacity block | 1‑yr reservation | 3‑yr reservation | Pricing sources |
|---|---|---|---|---|---|---|---|
| Modal | $6.25/hr | n/a | n/a | n/a | n/a | n/a | Modal pricing |
| Baseten | $9.98/hr | n/a | n/a | n/a | n/a | n/a | Baseten pricing |
| RunPod | n/a | n/a | $5.99/hr | n/a | ~$5.09 hr | n/a | Runpod pricing |
| Lambda Labs | n/a | n/a | $3.79/hr | n/a | $3.49/ hr | $2.99/hr | Lambda Labs pricing |
| AWS | n/a | n/a | $14.24/hr | $8.14/hr | ~$12.50/hr | n/a | Vantage, AWS Saving Plan, AWS Capacity Block pricing |
| GCP | n/a | $8.06/hr | $18.53/hr | n/a | $11.12/hr | $7.09/hr | Vertex pricing, Google Cloud pricing, Spot pricing |
Note that B200s are only available in instances of 8 GPUs on AWS and GCP
Choosing the right provider
Different scenarios call for different providers:
| Scenario | Best fit | Rationale |
|---|---|---|
| Bursty AI inference traffic | Modal | Per-second billing and sub-second cold starts keep effective cost lowest |
| Static, predictable AI inference traffic | AWS, GCP | Most reliable option that offers reservation-based discounts |
| Multi-week training runs | Lambda Labs | Cheapest reservation prices |
Serverless options like Modal automatically scale up and down from 0 so you only pay for compute you actually use. Reserved-capacity options provide a fixed block of resources; this is acceptable for static workloads but for variable workloads results in increased latency when demand is high and wasted money when demand is low.
On‑premise options: buy a B200 or DGX B200?
For those considering ownership:
- Standalone B200 SXM module: $30,000 - $40,000 (one 700W GPU board)
- Grace-Blackwell GB200 Superchip: $60,000 - $70,000 (1x Grace CPU + 2x B200)
- NVIDIA DGX B200: ~$515,000 (8x B200, 1.44 TB GPU RAM, 72 PFLOPS FP8)
At $30k per card, breakeven against $6-8/hour cloud rates happens at ~60% utilization over 18 months (excluding electricity and cooling). Factor in datacenter space (~14 kW per DGX B200) and staff before buying.
B200 vs. H100/H200: is the upgrade worth it?
The B200 offers compelling advantages for specific workloads:
- Memory headroom - 192 GB HBM3e lets you serve GPT-4-class 400B parameter models on one card instead of 2-way sharding
- FP4 Transformer Engine - 5x higher inference throughput; MLPerf Llama-2-70B results show 2-3x tokens/second on identical node counts
- Fifth-gen NVLink - 1.8 TB/s cuts all-reduce time ~40% in 8-GPU training replicas
- Better real-world latency - Modal’s benchmarks show 2.5x lower TTFB versus H200 for MoE models
Quick‑start guide: run code on a cloud B200 in under 5 minutes
Modal’s serverless platform lets you run and deploy code on a B200 without having to manage cloud resources. To get started, simply sign up and run the code snippet below:
import modal
app = modal.App()
@app.function(gpu="B200")
def run_big_model():
# This will run on a B200 on ModalAt $0.001736/second, you can benchmark for pennies, then scale to thousands of ephemeral workers without touching an instance planner.
Get started with B200s today
Modal serverless B200s at $6.25/hour is the most cost-effective option for bursty workloads.
If your H100s are out of memory or your user-visible latency targets are slipping, Blackwell’s 192 GB HBM3e and FP4 Tensor Cores are the most cost-effective escape hatch available today.
