Burst render capacity with hardware video encode.
A render queue is the ideal cloud workload: entirely parallel, bursty, and finite. Spinning up eight 4090 instances for two hours costs about $7 and finishes a job that would take a single workstation a day and a half.
Ada-generation cards carry dual NVENC engines, which turns final-frame encoding from a CPU bottleneck into a background task. If your pipeline ends in ProRes or H.265 delivery, the L40S will save more wall-clock time than its raw render figures suggest.
