Just like Intel's CPUs, Intel GPUs are allegedly vulnerable to performance penalties from security mitigations. Phoronix reports that disabling Intel graphics security mitigations for its OpenCL and Level Zero compute stack in Linux can boost performance by up to 20%.
Canonical, the makers of Ubuntu, are looking to disable these security mitigations in their OS due to the enormous performance impact these mitigations have on Intel GPUs. Intel reportedly allows its GPU compute stack to be built without security mitigations, enabling Canonical to achieve its goal without hunting down unofficial deactivation methods.
