As I'm currently looking for a new notebook, I also had to deal with the different components…
Often I noticed that different laptops from different manufacturers with the same CPU, iGPU, the same memory and the same hard drive in the benchmarks often deliver very different results.
Therefore, I now ask myself as a proven computer Laie how the same or similar equipment comes about.
Thank you for taking the time. I would be glad, if someone can help me with this.
In benchmarks (especially in games) you often have some fluctuations, because you for example. In various situations bencht.
Then it may still be that never laptops have a different resolution. Higher resolution also attracts more power.
I'm almost certainly with identical equipment there are only minimal differences, which may be due to the configuration of the operating system.
The components are similar, but not the same: z.b. A cheap hard drive with 5400U and small cache does not provide the same as a generously sized 7200U hard drive. And the same is true of all other components.
Motherboard and thus the chipset are sometimes very different.
The internal structure plays a decisive role in air circulation: the faster the components get hot, the worse the performance.
