Common questions
Google TPU v4 vs NVIDIA T4 Tensor Core GPU: which is faster for training?
Google TPU v4 has 4.23x the dense FP16/BF16 throughput of the other (Google TPU v4: 275 TFLOPS; NVIDIA T4 Tensor Core GPU: 65 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 NVIDIA T4 Tensor Core GPU: which has more memory?
Google TPU v4 carries more HBM (Google TPU v4: 32 GB HBM2; NVIDIA T4 Tensor Core GPU: 16 GB GDDR6). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Google TPU v4 vs NVIDIA T4 Tensor Core GPU: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: Google TPU v4 1.43 (275 ÷ 192 W); NVIDIA T4 Tensor Core GPU 0.93 (65 ÷ 70 W). Google TPU v4 wins at the die level; system-level efficiency also depends on cooling and interconnect.
Google TPU v4 vs NVIDIA T4 Tensor Core GPU: which is more widely used?
Google TPU v4: 0 robots and 2 data centers publicly running it. NVIDIA T4 Tensor Core GPU: 0 robots and 0 data centers. Empty here means no operator has said publicly, not zero adoption in the market.
