M3 Pro RAM bandwidth is slower than M2 Pro?

Apple released a new generation of chip M3 series earlier. The main feature of M3 chip is the use of 3 nm process, which improves the performance by about 15%. At the same time, it also adds the core of RT ray tracing to make gaming and graphics more convenient. At the same time, the performance of ray tracing can be improved by 2.5 times, but one aspect of the design is shrunk, which is the memory bandwidth.

The biggest feature of the M series chips has always been the unified memory design. Although it gives up the advantage of replaceable RAAM, the speed can be greatly improved, but the M3 Pro chip It is somewhat emasculated, only 150 GB/s. The memory bandwidth of the previous generation M2 Pro is 200 GB/s. But the magic is that compared with M2 Max, the speed of M3 Max is also 400GB/s. It can be seen that M3 Pro is replaced by Apple. Castrated part of the effectiveness.

We don’t know why Apple made this decision, but recent changes in Apple’s various behaviors and policies show that they are constantly reducing resources in the hope of earning more More income.
