After all, I can badly ask for a fps number in the sales store
The components that are installed and how well they communicate with each other.
In terms of processing power, graphics chip performance, hard drive speed, and maybe still efficiency.
The overall performance can actually best be seen in benchmark results
For graphics cards, you can still ask for flops, an Nvidia GeForce RTX 2070 has e.g. The values: 7465 GFLOPS (single), 233 GFLOPS (double)
This is also possible with CPUs, but that has very little informative value compared to graphics cards.
Then of course you can ask the speed of the disk, this is very important for Office and multimedia and affects the performance in the tasks by far the most!
For this you can still ask for the RAM, its size and speed and CPUs of the same generation can also ask the core number and clock rate. However, you should by no means compare different generations and architectures, since the performance per core and clock can be enormously different!
