When a guitarist, with a pocketful of cash, goes into a shop that has a wall full of what appear to be the same model of guitar, just different colours, he will try one after the other. None seem “right”. Then he picks up one, and it sits just so, the feel of the fretboard is just right, the sound of the pickups through the same amp in to which all the others were plugged, is sweet, and yet, to the naked eye, it looks just like all the rest. (I speak from experience, and any guitarist here will tell you the same.)
There’s a web site, https://www.passmark.com, which has software which measures the performance of hardware, (CPUs, GPUs, drives, RAM) and displays the results in a table (https://www.cpubenchmark.net). From the results, you can see that people have different results from apparently the same hardware.
Hardware, instruments, are manufactured to baseline specs, within certain tolerances. If it falls outside those tolerances, it is discarded (one hopes).
Now if the aggregate of a computers hardware is close to those baselines, the computer will work just dandy. But if, for example, the CPU is close to the extreme lower end of the tolerance range and the GPU is at the other end, maybe this is when a computer is problem.
Just musing, here.
