Common questions
NVIDIA DRIVE Thor vs NVIDIA GB300 (Blackwell Ultra): which is faster for training?
NVIDIA GB300 (Blackwell Ultra) has 2.50x the dense FP8 throughput of the other (NVIDIA DRIVE Thor: 2,000 TFLOPS; NVIDIA GB300 (Blackwell Ultra): 5,000 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
NVIDIA DRIVE Thor vs NVIDIA GB300 (Blackwell Ultra): which has more memory?
NVIDIA GB300 (Blackwell Ultra) carries more HBM (NVIDIA DRIVE Thor: 128 GB LPDDR5X; NVIDIA GB300 (Blackwell Ultra): 288 GB HBM3e). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
NVIDIA DRIVE Thor vs NVIDIA GB300 (Blackwell Ultra): which is more power-efficient?
Dense FP8 TFLOPS per watt: NVIDIA DRIVE Thor 15.38 (2,000 ÷ 130 W); NVIDIA GB300 (Blackwell Ultra) 3.57 (5,000 ÷ 1400 W). NVIDIA DRIVE Thor wins at the die level; system-level efficiency also depends on cooling and interconnect.
NVIDIA DRIVE Thor vs NVIDIA GB300 (Blackwell Ultra): which is more widely used?
NVIDIA DRIVE Thor: 11 robots and 0 data centers publicly running it. NVIDIA GB300 (Blackwell Ultra): 0 robots and 1 data center. Empty here means no operator has said publicly, not zero adoption in the market.
