I had a random thought while out for a walk today. The M1 and the A14 reportedly use the same core design for their performance and efficiency cores. The A14 has two performance cores and four efficiency cores. The M1 has four of each. We have multicore Geekbench scores for both the A14 and the M1. So, with a little algebra, we can figure out how many points each type of core contributes to the multicore Geekbench.

```
2p + 4e = 4203
4p + 4e = 7689
p = 1743
e = 179.25
```

Now, this comes with a boatload of caveats. Modern processors are complicated and there are reasons even the multicore version of Geekbench might not scale exactly linearly with the number of cores as I’m assuming. Not to mention the fact that I’m completely ignoring the fact that the M1 is clocked slightly faster than the A14. I’m just going for a very rough estimate here.

With those caveats in mind, let’s take a look at the rumored MacBook Pro chip with two efficiency cores and eight performance cores. Plug in the numbers above and you get a theoretical Geekbench multicore score 14302.5.

Just to put that in perspective, here’s the Geekbench multicore Mac leaderboard:

A 14,302 would slot the new MacBook Pro just under a Mac Pro with a 16-core Xeon.
