It's not RAM like RAM. In computer science, this abbreviation refers to a semiconductor memory with direct access that enables both reading and writing (Random Access Memory). But it is different in Apple Silicon computers and those using Intel processors. In the first case, it is a unified memory, in the second, a classic hardware component. 

New Apple computers with Apple Silicon chips have brought higher performance with lower energy consumption because they are built on the ARM architecture. Previously, on the contrary, the company used Intel processors. Computers with Intel therefore still rely on classic physical RAM, i.e. an elongated board that plugs into a slot typically next to the processor. But Apple switched to unified memory with the new architecture.

All in one 

RAM works as a temporary data storage and communicates with the processor and graphics card, between which there is constant communication. The faster it is, the smoother it runs, because it also puts less strain on the processor itself. In the M1 chip and all its subsequent versions, however, Apple has implemented everything in one. It is therefore a System on a Chip (SoC), which simply achieved the fact that all components are on the same chip and thus minimizes the time required for their mutual communication.

The shorter the "path", the fewer steps, the faster the run. It simply means that if we take 8GB of RAM in Intel processors and 8GB of uniform RAM in Apple Silicon chips, it is not the same, and the principle of operation of the SoC simply follows that the same size has the effect of overall faster processes in this case. And why do we mention the 8 GB? Because that is the core value that Apple provides in its computers for unified memory. Of course, there are different configurations, typically 16 GB, but does it make sense for you to pay more for more RAM?

Of course, it depends on your requirements and how you will use such a computer. But if it is normal office work, the 8GB is absolutely ideal for the completely smooth operation of the device, regardless of what work you prepare for it (of course, we do not count playing those really demanding titles).
