Increasing this number with Intel XTU will increase the power limits of your CPU, and will allow the CPU to boost higher. This will come at the expense of heat and higher fan noise. If you wish to play around with your CPU, voltages, turbo long/short max, then I'd advise you to use Throttlestop. Yes, Turbo Boost can affect gaming performance a lot. However, since you are asking if it does, it's safe to say you didn't notice the performance drop. Well when the game lags the CPU clock speed is 3400Mhz , CPU usage 25-35% and power usage is between 11 to 18 watts with major fps drops. You shouldn't limit the boost speed to achieve a fps cap. Instead you should go into your gpu driver settings and just set a fps cap. Setting a fps cap will preserve your minimum frame rate under max load, it also may even improve it due to having a cooler average cpu(and/or gpu) with more boost available in areas of high load. You may be able to squeeze a few more FPS out of these things, but realistically with computer hardware, there's a pretty tight band of performance for any component. That's further complicated with laptops, which generally push their thermal limits at stock and rarely have much headroom for considerably more heat (which any overclocking will Thanks to Turbo Boost Max 3.0 and Thermal Velocity Boost, the CPU's fastest core(s) can reach speeds up to 5.3 GHz, enhancing performance in lightly-threaded games. Multithreaded applications benefit from both TVB and Adaptive Boost, which enable an all-core turbo frequency up to 5.1 GHz. TKbGz.
