On November 1, graphic designer Bulzomi Anton posted that Apple updated the support page for the MacBook Pro equipped with M1 Pro and M1 Max chips, which updated the product details of this notebook on WiFi and other aspects, and said that the highest WiFi transmission specifications of the new MacBook Pro are not as good as the Intel version from 2017 to 2019.
Xiao Lei learned on Apple's official website that the MacBook Pro notebook of the M1 series chip has a maximum transmission rate of 1200Mbps under the standard of 802.11ax (WiFi6) and 5GHz, while the old model equipped with Intel chips from 2017 to 2019 has a maximum speed of up to 1300Mbps in the 802.11ac (WiFi5) and 5Ghz bands.
The biggest difference is also the number of channels, the Intel version of the MacBook Pro from 2017 to 2019 has 3 MIMO in the fuselage, and the new models in the future have only two. You know, the more MIMO means that the device has a stronger ability to send and receive signals, the new MacBook Pro may not be very different from the old model in terms of speed, but one less channel means that the signal reception ability is relatively weak.
Xiao Lei speculated that Apple may have improved the performance of a single MIMO channel, and only two MIMO needed to make the transmission efficiency of the new MacBook Pro close to the 2017 to 2019 Intel version. However, the premise is that the user must have a WiFi6 router, otherwise you can only experience the "castrated" version of WiFi5.
Foreign media 9To5Mac said that this situation may be because the M1 chip and the A series chip are of the same origin. At present, there are no iOS devices that support more than 2 MIMO, and Apple may not have considered supporting more than 2 MIMO when designing the M1 chip. Of course, fewer channels also help with the overall endurance of the device.
BulzomiAnton also said that he conducted multiple rounds of testing and found that the MacBook Pro of the M1 series of chips and the older Intel version of the two are very small in the actual use of the WiFi transmission rate of the two, and the users who have purchased it do not need to worry.
In fact, WiFi speed depends largely on factors such as network cables, routers, the number of connected devices, and transmission distance. Xiao Lei feels that if you recently bought the 2021 MacBook Pro, users who are not satisfied with the WiFi performance of the computer can consider a router with stronger performance.
