Can I deploy NVIDIA B300 or NVIDIA RTX 4070 Ti on Runcrate today?

NVIDIA B300 is on demand in 1 region from $11.05/hr, billed by the second on most GPUs. NVIDIA RTX 4070 Ti is not in stock on Runcrate right now; leave your email on its pricing page to register interest.

How much VRAM does each GPU have?

NVIDIA B300 has 288GB HBM3e. NVIDIA RTX 4070 Ti has 12GB GDDR6X.

B300 or RTX 4070 Ti: which holds a 70B model in 8-bit weights?

It needs 70 GB of 8-bit weights. On the B300: 1 GPU, 218 GB spare. On the RTX 4070 Ti: 7 GPUs, more than one 2x node. Pick the B300: fits on one GPU.

GPU comparison

B300 vs RTX 4070 Ti.

The B300 is ahead on memory (288 GB vs 12 GB) and speed (28.1x the FP16 throughput and up to 15.9x the memory bandwidth). The RTX 4070 Ti makes sense when your model fits in 12 GB and its hourly price is lower.
