Sit yourself down because this is where things can get a bit confusing. The M series of chips from Apple have been relatively simple to date. The M1 was replaced by the M2, then the M3 and now the M4. Within each of these there was also higher performance versions – the Pro, the Max and the Ultra. But when today Apple released the M3 Ultra alongside the M4 Pro and Max models, you may be left scratching your head.
The Ultra chip is a little different from the Pro and Max models. In fact, the best way to think about the Ultra is that it's two Max chips fused together, because that's exactly what it is. Apple uses UltraFusion technology to connect the chips and allow them to work as one, and the result it blisteringly fast.
