Dim Silicon and the Case for Improved DVFS Policies
Mathias Gottschlag, Yussuf Khalil, Frank Bellosa
Due to thermal and power supply limits, modern Intel CPUs reduce their frequency when AVX2 and AVX-512 instructions are executed. As the CPUs wait for 670μs before increasing the f…

Mechanism to Mitigate AVX-Induced Frequency Reduction
Mathias Gottschlag, Frank Bellosa
Modern Intel CPUs reduce their frequency when executing wide vector operations (AVX2 and AVX-512 instructions), as these instructions increase power consumption. The frequency is o…
