Latest macbooks is a downgrade even when it got wifi6. Used to max out at 650mbps, now it’s 450mbps

Are you sure it's not your AP?

My 2013 Thinkpad with factory WiFi card reaches 700Mbps with an higher-quality AP from approximately the same era.

My MBP 16 m1 easily does 750mbps with Unifi 6 LR

Up to 2019, Macbooks had ac 3x3 MIMO wifi. Since then, they have ax 2x2 MIMO.

If you have a nice wifi 5 AP, let's say Unifi nanoHD, you get better speeds with the older Macbooks (I had slightly gigabite, with 80 MHz wide channel and three streams). With the new Macbooks, you need wifi 6 AP to achieve similar performance (MCS 11, OFDM, 80 MHz wide channel, two streams); otherwise, with Wifi 5 (MSC 9) and two streams, you get theoretical 866 Mbps max.
