Just one week ago Linux block subsystem maintainer Jens Axboe was optimizing the kernel to get 8 million IOPS on a single CPU core. He progressed the week hitting around ~8.9M IOPS per-core and began to think he was hitting the hardware limits and running out of possible optimizations. However, this week he is kicking things off by managing to hit 10 million IOPS!..

Just one week ago was the public launch of the Radeon RX 6600 as the newest offering in the RDNA2 GPU line-up. While in our Radeon RX 6600 Linux review the performance was good on AMD's well regarded open-source driver stack and standing ground against the likes of the GeForce RTX 3060 with NVIDIA's proprietary Linux driver, it turns out the RX 6600 Linux performance can be even better already. Here are benchmarks of the Radeon RX 6600 on Linux across six different driver configurations.
