It sadly seems like Apple M3 is nerfed in different ways, so I decided to keep my solid old but gold M1 MacBook Air.
Also based on what I have read from performance tests, here is when it's worth considering buying a new Mac:
Apple M1 = Major performance boost, worth upgrading
Apple M2 = Small performance boost, NOT worth upgrading
Apple M3 = Small performance boost, NOT worth upgrading
Apple M4 = Small performance boost, NOT worth upgrading
Apple M5 = Major performance boost, worth upgrading
Apple M6 = Small performance boost, NOT worth upgrading
Apple M7 = Small performance boost, NOT worth upgrading
Apple M8 = Small performance boost, NOT worth upgrading
Apple M9 = Major performance boost, worth upgrading
Yes, that's every 4th Apple M version, so at maximum every 5 or 6 years. In other words,
save your money and time and spend it on your loved ones instead, no need to upgrade every year.
Also Apple should really stop with their obvious 2010 base model Mac specs, like 8 GB RAM/256 GB SSD in 2023 really Apple?
