The MacBook Pro, based on Apple’s M1 silicon, has a different type of RAM to what’s gone before. This is what Apple is branding ‘unified memory’, where the RAM is part of the same unit as the processor, the graphics chip and several other key components. This is called a system on a chip (SoC), which is more commonly found in smartphones and tablets.

With everything sharing the one pool of memory, you might think that Apple would want to include more RAM, not less than before, but the reams of benchmarks Apple shared last night suggest the company is confident that even a limited allocation of RAM will outperform most equivalent PCs.

We will have to wait for independent benchmarks to be carried out on the new Macs before anyone can verify those claims. The benchmark graphs that Apple showed in last night’s keynote were extremely vague, not revealing which specific PCs or PC processors the comparisons were being made with.

Hard 16GB limit

There’s another reason Apple isn’t taking its traditional approach of charging customers a hefty premium to include more RAM in their MacBooks: it can’t. Currently, the M1 cannot support more than 16GB of memory.
