So, there is not much clear answer lying around the internet, but I am still seeking for one. Supposed if I were to compare, a Desktop with Intel i5 6700K vs a Laptop with Intel i5 6700U; with the desktop being underclocked & TDP limited down to meet 6700U being overclocked.
In general sense, will both Desktop and Laptop perform the same or will there still be performance difference?
2I think this question is too broad. You can check CPU performance benchmarks for the specific CPUs you want to compare; all other measures of "performance" depend on many other hardware-related factors and the concrete task whose performance you are measuring. – slhck – 2019-04-24T09:22:35.313
1In most cases the desktop will be faster because it contains better (and larger) components. – harrymc – 2019-04-24T10:02:04.830
@harrymc I disagree that a desktop CPU will be faster because it contains better or larger components. While this may be true, there are quality notebooks and rubbish desktops. A lot of the "better" in desktop components have to do with "better able to handle heavier power draw", which would be moot if you underclocked the desktop variant and oveclocked the laptop variant - ignoring the instabilities and problems which can arrise from overclocking. – davidgo – 2019-04-24T11:10:16.547
@davidgo: I'm not talking about the CPU but of the entire box: RAM, bus, controllers etc. A laptop doesn't have all the components for optimal performance, and mobile CPUs emphasize power consumption over performance. Some extreme gaming laptops achieve desktop performance, but they are costly and power-hungry. – harrymc – 2019-04-24T11:20:07.503
