I have a laptop with an RX 530 Series 8GB Ram and an i7 8565u processor.
When I run Cinebench, the CPU is only used 60%. It can't be a heat problem because the fan turns down during the run.
I also plugged the power plug into the PC so that it can clock up nicely, but that doesn't work.
My Cinebench r23 values in the multi core are around 1500, but the value should be twice as high.
Do you know a solution to the problem?
The Core i7-8565u has a nominal TDP of only 15 watts (can still be configured by the manufacturer between 10 and 25 watts) and accordingly only has a minimum clock frequency of 1.80 GHz.
The 4.6 Ghz maximum turbo boost can only be achieved for a very short time with such processors, even with sole load on a single core & thread, to accelerate the response of applications.
If the notebook manufacturer has adjusted the SoC of your book to a maximum of 10 watts TDP, the clock rate will also remain considerably lower than with a maximum TDP configured to 25 watts. (The NB manufacturer can determine this himself)
You also have to check whether you have selected a single-core or multicore bench in Cinebench r23. With SC, 1000 to 1500 points come in roughly. (depending on the TDP adjustment)
I chose the multi-core test, but since only half of the possible CPU multi-core performance is queried, 1500 points are quite good. Even in the single core, a core clocks up to a maximum of 2.6 GHz instead of 4.6 GHz. So there's no way to increase the maximum power consumption of the processor? So that can only be decided by the manufacturer? It would be a bit of a mistake if I can't set this myself anywhere, because then I won't use an i7 if I don't even have half of the multi-core power available, because I render videos every now and then.
Nevertheless, thank you very much for your helpful answer!
My pleasure.
With regard to the multicore load you have to run the task manager, because physically the i7-8565u only has 4 cores and can derive 8 logical threads from them via SMT. In the CB r23, a Core i7-6700 vs. I5-6600K can only set itself apart from the i5 by around ~ 20% in the multicore bench. As expected, they are roughly the same for single core.
However, you have to look in the CB settings to see that "Max. Threads" is also set, because even in the standard TDP of 15 watts, the i7-8565u on the r23 should actually have (clearly) over 2000 points in the multicore come. In addition, set the maximum performance for the benchmark in the book in the Windows energy profile.
Something else about the Windows task manager:
In the case of processors with SMT function, the only ever shows a maximum load of up to 50% per thread… Is such a peculiarity of the tool.
