Common questions
AMD Instinct MI325X vs NVIDIA Jetson AGX Thor: which is faster for training?
AMD Instinct MI325X has 1.26x the dense FP8 throughput of the other (AMD Instinct MI325X: 2,614 TFLOPS; NVIDIA Jetson AGX Thor: 2,070 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
AMD Instinct MI325X vs NVIDIA Jetson AGX Thor: which has more memory?
AMD Instinct MI325X carries more HBM (AMD Instinct MI325X: 256 GB HBM3e; NVIDIA Jetson AGX Thor: 128 GB LPDDR5X). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
AMD Instinct MI325X vs NVIDIA Jetson AGX Thor: which is more power-efficient?
Dense FP8 TFLOPS per watt: AMD Instinct MI325X 2.61 (2,614 ÷ 1000 W); NVIDIA Jetson AGX Thor 15.92 (2,070 ÷ 130 W). NVIDIA Jetson AGX Thor wins at the die level; system-level efficiency also depends on cooling and interconnect.
AMD Instinct MI325X vs NVIDIA Jetson AGX Thor: which is more widely used?
AMD Instinct MI325X: 0 robots and 0 data centers publicly running it. NVIDIA Jetson AGX Thor: 11 robots and 0 data centers. Empty here means no operator has said publicly, not zero adoption in the market.
