When locking the CPU to 99% on the boosted profile or using a ThrottleStop profile that disables turbo I get the same FPS increase suggesting that this is somehow directly related to allowing the CPU to boost. My best guess is that with the boosting disabled, more resources can be used to focus on the GPU. Discussion In the past I didnt really care about overclocking my cpu or adjusting something else because I thought that the turbo boost is well optimized for the best performance. But now I started noticing really high temps (under full load 80-90C). It can be seen from the formula that turbo boost disabling increases average FPS in games on almost all ultrabooks (by preventing throttling). U-chips in ultrabooks have a 10-15-watt TDP and a slight difference between base and turbo frequencies so turbo boost disabling is useful for gaming. 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. It is more clever to set a thermal limit with Ryzen controller (like 85C) to still have the boost possibility and get lower temps. Performance loss can be up to 35% in single core dependent usecases like browsing, Excel, strategy games, Also frame dips are alot more likely and severe without boost. Dunotuansr. 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. Does Turning Off Turbo Boost Affect My Intel Graphics Performance - Troubleshooting - Linus Tech Tips Home The Workbench Troubleshooting Does Turning Off Turbo Boost Affect My Intel Graphics Performance Does Turning Off Turbo Boost Affect My Intel Graphics Performance By TH3N00BK1N9 April 3, 2021 in Troubleshooting TH3N00BK1N9 Member 36 Overall, it has to be said that in some cases, Turbo Boost will let the game reach a higher FPS; but maybe only a 10-20 FPS boost. Moreover, if you disable the Intel Turbo Boost, it will hurt your gaming performance and other performances. AVSASry.
