Cpu speed - nitro 5 -55

Hello ,i have nitro 5 -55 i5 10300h 2.5 and doing bench marks turbo only goes up to 3.5ghz not the 4.5 its supposed to,have used cpu-z and user bench marks both say same,dont think its thermal throttling as i have tested in different conditions and just hits that ceiling,any ideas?

You have to understand and know the theory behind "Intel Turbo Boost" first as the reason you are not getting the full turbo speed quoted is because of heat and the laptops ability to disperse the heat at 4.5GHz which you need a good setup like water cooling to sustain and to utilise for long periods of time, as a two small fan laptop thermal setup will never ever be able to sustain this high CPU speed for long period of time. Here is a brief explanations for you of Turbo Boost:

What is Turbo Boost? This is a technology used in some Intel CPUs to dynamically increase clock speed. Through turbo boost the PC performance can be improved temporarily for handling heavy loads. Programs can be divided into GPU-intensive ones, RAM-intensive ones, or CPU-intensive ones. Therefore, when you run programs, CPUs don’t always need to run at their maximum frequency. In addition, if CPUs always run at high frequency, they will consume more power and produce more heat, which will shorten CPU lifespan and power supply lifespan.

How much can the Turbo Boost technology increase CPU speed? Actually, it can potentially increase CPU speeds up to the Max Turbo Frequency while staying within safe temperature and power limits. For example, the Intel Core i9-9900K processor has a base frequency of 3.60 GHz, and a Max Turbo frequency of 5.00 GHz. The Max Turbo Frequency reflects the processor’s peak performance before (real) overclocking. It’s one of the key considerations when CPU shopping. But please note that depending on its situation, a given CPU may not always reach its Max Turbo Frequency. The dynamic increase in speed changes is dependant on the workload and the thermal headroom available.
