Groq LPU vs. NVIDIA H100: Echtzeit-Inferenz im Leistungsvergleich

While NVIDIA GPUs dominate model training through raw FP8 tensor throughput, inference token generation is bound by memory bandwidth rather than compute arithmetic. Groq LPUs discard slow external DRAM/HBM entirely, embedding 230MB of ultra-fast on-die SRAM with a staggering 80 TB/s bandwidth, rendering token generation truly instantaneous.

Memory Wall: On-Die SRAM vs External HBM3e

In autoregressive generation, each token generated requires transferring all billions of model weights from memory to the compute cores. An H100 HBM3e bandwidth of 3.35 TB/s caps single-stream 70B model speed at roughly 45 tokens/second. In contrast, Groq nodes link hundreds of LPUs with direct point-to-point connections, streaming weights from on-chip SRAM at over 80 TB/s.
