Is it theoretically possible to determine the presence or absence of the bottlenecking effect in the system?

Question

Iron

In the common people, this question sounds like "will this processor open this (or these, if there are two or more) video cards?". What exactly is the processor? and most importantly: can it be calculated based on the characteristics of these two pieces of iron?

Answer 1

Of course a lot. The more you rummage around in the system, in the hardware, the easier it is for you to theoretically find where the bottleneck is in the system, without unnecessary tests.
Tests are needed in case you are not sure.
The probability of finding a specialist who, purely theoretically, will design the system so that all components work 100% is extremely small. Therefore, they use tests and utilities.

Answer 2

in general, you don’t have to bother too much, you can take hardware of about one year of release, then the probability of the effect will not be high, in any case, all modern games rest against anything, not because it’s not enough, but because the engine is not optimized, in such games at least Insert 15 video cards will still be stupid. If you want smooth graphics, you need to take ps4, there this problem does not make sense
