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.

Tau VM instances are now available as a preview and Google has provided us with gratis access to the new instance types for benchmarking.

Made public this week by CPU security researchers at Graz University of Technology and CISPA Helmholtz Center for Information Security was the research paper published "AMD Prefetch Attacks through Power and Time". The paper points to AMD CPUs suffering from a side-channel leakage vulnerability through timing and power variations of the PREFETCH instruction. The paper argues that AMD CPUs should activate stronger page table isolation by default. AMD has now published their security response where they are not recommending any mitigation changes at this time. But what if Kernel Page Table Isolation (KPTI/PTI) proves necessary for AMD CPUs? Here are some initial benchmarks showing what that performance impact could look like.
