Chip comparison
Google TPU v4 vs Groq LPU (Language Processing Unit)
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
Google TPU v4 vs Groq LPU (Language Processing Unit): which is faster for training?
Google TPU v4 has 1.46x the dense FP16/BF16 throughput of the other (Google TPU v4: 275 TFLOPS; Groq LPU (Language Processing Unit): 188 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
Google TPU v4 vs Groq LPU (Language Processing Unit): which has more memory?
Google TPU v4 carries more HBM (Google TPU v4: 32 GB HBM2; Groq LPU (Language Processing Unit): 0.23 GB SRAM (230 MB on-die)). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Google TPU v4 vs Groq LPU (Language Processing Unit): which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: Google TPU v4 1.43 (275 ÷ 192 W); Groq LPU (Language Processing Unit) 0.50 (188 ÷ 375 W). Google TPU v4 wins at the die level; system-level efficiency also depends on cooling and interconnect.
Google TPU v4 vs Groq LPU (Language Processing Unit): which is more widely used?
Google TPU v4: 0 robots and 2 data centers publicly running it. Groq LPU (Language Processing Unit): 0 robots and 0 data centers. Empty here means no operator has said publicly, not zero adoption in the market.
