A June 21, 2026 publication reports 6.6× scaling on eight GPUs in a worst-case test and throughput above 100 million steps per second on eight RTX 5090 GPUs.
A publication dated June 21, 2026 presents multi-GPU scalability results for PufferLib 4.0. In the described worst-case test, a policy with 32 times as many parameters achieved 6.6× scaling on eight GPUs. The publication also reports peak throughput above 100 million steps per second on eight RTX 5090 GPUs.
These figures offer a performance reference for GPU workloads, not a guarantee for other configurations. To assess them, consult the original publication and verify the test conditions, what “worst case” means, the metrics, and the reported hardware; compare only with measurements made under equivalent conditions.
