Common questions
Groq LPU (Language Processing Unit) vs Intel Gaudi 3: which is faster for training?
Intel Gaudi 3 has 9.76x the dense FP16/BF16 throughput of the other (Groq LPU (Language Processing Unit): 188 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.
Groq LPU (Language Processing Unit) vs Intel Gaudi 3: which has more memory?
Intel Gaudi 3 carries more HBM (Groq LPU (Language Processing Unit): 0.23 GB SRAM (230 MB on-die); Intel Gaudi 3: 128 GB HBM2e). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Groq LPU (Language Processing Unit) vs Intel Gaudi 3: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: Groq LPU (Language Processing Unit) 0.50 (188 ÷ 375 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.
