Die area is drawn against the largest recorded die in the catalog. Shader dots use a labeled, card-specific ratio so both early and modern GPUs remain legible.
Catalog context
Within its series, the L40 GPU accelerator ranks first of 36 for FP32 throughput and 7th of 32 for memory capacity. Its 300 W TDP is above the 75 W PCIe slot-power ceiling.
