The Initial Performance Of NVIDIA's R515 Open-Source Linux GPU Kernel Driver

As outlined in yesterday's extensive article about NVIDIA's new open-source Linux kernel GPU driver, currently for consumer GeForce RTX GPUs the driver is considered of "alpha quality" while NVIDIA's initial focus has been on data center GPU support. In any event with having lots of Turing/Ampere GPUs around, I've been trying out this new open-source Linux kernel driver on the consumer GPUs. In particular, I've been curious about the performance of using this open-source kernel driver relative to the default, existing closed-source kernel driver. Here are some early benchmarks.
