Tesla P100 F16 results surprisingly low

I am trying to undestand why the F16 performance of my Tesla P100 is really no higher than the F32 result. Nvidia's datasheet https://images.nvidia.com/content/tesla/pdf/nvidia-tesla-p100-PCIe-datasheet.pdf implies that the P100 should have twice the half precision performance compared to full precision but according to my Geekbench ML score https://browser.geekbench.com/ml/v0/inference/360072 this is not the case.

Any insight? And please, none of that "Pascal is really old" stuff. I know it is. If the whitepaper says the performance should be there, why can it not be seen in practice?
