| Action | Technology (standard name) | Comment |
|---|---|---|
| Enable | E‑Cores (Energy Efficient Cores) | You must enable all CPU cores (including energy-efficient ones) to achieve the actual load corresponding to the calculations of performance calculator |
| Disable | Turbo Boost (Intel Turbo Boost, AMD Turbo Core) | When you enable Turbo Boost, clock speed can dynamically change depending on temperature and load. In systems with different cooling systems, this leads to inconsistent performance on servers even with identical CPUs |
| Hyper-Threading (SMT—Simultaneous Multi-Threading) | In some configurations, Hyper-Threading can cause an uneven load on logical cores, which reduces the efficiency of processing video streams | |
| Intel Speed Shift (Speed Shift Technology) | This technology allows the operating system to quickly change the CPU clock speed. Disabling this feature ensures that the clock speed doesn't drop below the base clock speed | |
| Enhanced Intel SpeedStep (EIST) | Technology for dynamic adjustment of voltage and clock speed depending on the load. Disabling this feature prevents reduction in CPU clock speed | |
| Energy Saving (C-States, P-States, AMD Cool’n’Quiet, AMD PowerNow!) | All power-saving modes that reduce the CPU clock speed and voltage when idle. Disabling these modes is necessary to maintain a stable clock speed at the base level | |
| Smart Throttling (Thermal throttling) | Technology for automatic reduction of clock speed when a temperature threshold is reached. If the cooling system allows, disabling this feature helps avoid sudden performance drops |
