**Is the B300 faster than the B200?**

On dense FP16 tensor throughput the B300 leads by about 1.2× (2,800 vs 2,250 TFLOPS). Memory bandwidth matters as much for inference: B200 8,000 GB/s vs B300 8,000 GB/s.

**Which is cheaper to rent, the B200 or the B300?**

The B200: $5.425/hr on-demand versus $6.737/hr — 19% less. Interruptible rates are $2.712 (B200) and $3.368 (B300). Per TFLOP-hour the better value is the B300.

**Which has more VRAM and what does that change?**

The B300 has 288 GB versus 192 GB. In LLM terms that is roughly a 105B FP16 model (or ~405B in 4-bit) on one card against 72B FP16 (~235B 4-bit). If the model does not fit, speed is irrelevant.

**Can I rent both on PowerGPU right now?**

Yes — 32 × B200 and 34 × B300 are online as this page renders, deployable in about 30 seconds, billed per second, paid in crypto with no KYC.
