Apple has reduced the memory bandwidth of the new M3 Pro processor by a quarter compared to the M1 Pro and M2 Pro processor

Apple unveiled a new chip this week. It's called the Apple M3 Pro. The processor made its debut in MacBook Pro laptops. As it turned out, the company significantly cut the memory bandwidth.

Here's What We Know

M3 Pro is manufactured using a 3-nanometre manufacturing process. The company claims that thanks to the chip, the performance growth of new laptops can reach 40% compared to MacBook Pro 15 on the M1 Pro.

At the same time, the unified memory bandwidth was 150 GB/s, which is 25% lower than the M1 Pro and M2 Pro chips (200 GB/s). Also noteworthy is the decrease in this figure for the M3 Max with 14-core CPU and 30-core GPU. This version of the chip has a memory bandwidth of 300 GB/s versus 400 GB/s for the M3 Max with a 16-core CPU and 40-core GPU, the same as all M2 Max chips.

The new M3 Pro processor has six performance cores and has the same number of power efficient cores. The configuration on the M2 Pro is 8 + 4. At the same time, the number of graphics cores has been reduced from 19 to 18 units.

It's not quite clear why Apple compared the M3 Pro to the M1 Pro. Perhaps, when comparing it to the M2 Pro, the superiority of the new processor would not be so impressive. How things with performance in practice, we'll find out in a week. Sales of the new notebooks will start on November 7, 2023.
