Chip comparison
Intel Gaudi 2 vs Intel Gaudi 3
Side-by-side specs
Straight from each vendor's datasheet. Winner in bold: higher throughput, memory, or transistor count; lower power draw or price. Sparse (2:4) throughput roughly doubles the FP8/INT8 numbers shown.

Common questions
Intel Gaudi 2 vs Intel Gaudi 3: which is faster for training?
Intel Gaudi 3 has 4.25x the dense FP16/BF16 throughput of the other (Intel Gaudi 2: 432 TFLOPS; Intel Gaudi 3: 1,835 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
Intel Gaudi 2 vs Intel Gaudi 3: which has more memory?
Intel Gaudi 3 carries more HBM (Intel Gaudi 2: 96 GB HBM2e; Intel Gaudi 3: 128 GB HBM2e). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Intel Gaudi 2 vs Intel Gaudi 3: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: Intel Gaudi 2 0.72 (432 ÷ 600 W); Intel Gaudi 3 2.04 (1,835 ÷ 900 W). Intel Gaudi 3 wins at the die level; system-level efficiency also depends on cooling and interconnect.
