Figures are dense. Where a vendor publishes a figure it sits under the dense one and never decides a winner. Hover any precision for its definition, or read the GPU glossary.

FLOPS by Precision

What actually differs

The L600 is the newer part: GCU-CARA 4 (2025) against the Yunsui T20's GCU / DTU 2.0 (2021).

The L600 carries 112 GB more memory (144 GB against 32 GB), so larger models fit on one GPU before you shard.

Power is 300 W against 700 W, and at FP32 the Yunsui T20 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
