r/macbookpro on Reddit: A short review of the 2021 Macbook pro 16 inch "base model" as someone using it for large scale data analysis
November 30, 2021 -
I work in neuroscience (finishing my PhD), and primarily use MATLAB to analyze large amounts of neural and hemodynamic time courses. Up until now, I've been remotely accessing an enterprise server in my lab to do all of my data analysis. I just transitioned my primary workflow to my new 16" MacBook, and I wanted to share a comparison of computation speeds:
Task: Loading ~180 92x12000 matrixes, applying a sliding correlation window to each, then k-means clustering an exemplar dataset 100 times (size: 1770x8464)
Here are the execution times for identical scripts:
Macbook Pro: 143 seconds
Enterprise Server: 234 seconds
I'm not sure of the exact specs of the server I use, but I do know it is <4 years old, and does get used regularly by others, so is probably sharing a computation load with other processes. It's also not well optimized for MATLAB, and is entirely CPU computation side to my knowledge.
Conclusion: The base model is really fast.

This is because of superior single core performance of M1. If the matlab code is properly parallelized this would not be the case as the server should have 20-24 cores or 40-48 threads. Probably your code is not scaling well. I have the same experience with my MPI code. 24 core mac pro and M1 pro show same performance because the code is most efficient at 10-15 threads. This is because I have lot more optimization to do.

The server comparison is worthless if you don’t know its specs or its actual workload from other processes.

MacBook Pro 16" M1 Pro review | MacRumors Forums
I get awesome battery life on the 2019 MBP but the 2021 model battery life is incredible. ... Nice review OP. I also prefer the body of the previous model. The 16" is just too large in my opinion and prior to this model the 16" models were all I used. It just felt awkwardly big to me. I also prefer the keyboard design of the previous model with the body color in between the keys. The all black design is off putting to me. It would look spectacular on an all black MacBook Pro...

2021 16-inch MacBook Pro review: One year later, still worth buying | AppleInsider
December 20, 2022 - So far, that hasn't been the case with the new MacBook Pro. The keyboard is responsive and fast, the display looks incredible and vivid, and the M1 Max has crushed it. We'd still have preferred four Thunderbolt ports instead of three with HDMI and a SD card reader, but you can't always get what you want. For most users, we recommend either the stock M1 or M2 MacBook Air. If you need more power, or are looking at nearly any upgrade at purchase to the M2 MacBook Air, the 14-inch or 16-inch MacBook Pro with either the M1 Pro or M1 Max Apple Silicon is an excellent machine for about the same price given the sales we've seen lately.

We are going to answer this question, ... really special. Usually, manufacturers rely on Intel or AMD when it comes to processors and AMD and NVIDIA for their graphics cards. The truth is, Intel was in its own league for a long time, and this led to only incremental upgrades being made. Of course, Apple didn't like that. The result of this is the M1 chip.
