I have a i7 laptop of the same generation that I'm using to type this. I've replaced the screen, bezel, keyboard, touchpad, WiFi board, charger (3 or 4 times, thanks a lot Dell), battery. Upgraded the memory and added an SSD. Reapplied CPU paste once or twice. Never had a single problem with the CPU. Actually I don't know that I've ever had a computer with a CPU failure.
In all I've spent about 25% of the cost of the laptop over the years in repairs, but the result is that I'm able to keep using a device that's almost 12 years old instead of junking it. Saved quite a bit of money vs a new device, too.
Incidentally, it's interesting in regards to this issue that these old bulky laptops with beefy chips are actually quite good at avoiding thermal throttling. Despite having a traditional loud fan, I rarely even hear it come on.
For non-brits: Triggers broom is a joke revolving around the ideas of the ship of theseus.
In the show, trigger is a street sweep who has "kept the same broom" for 10 years, only periodically replacing the brush and occasionally replacing the handle.
The joke is of course, that it's no longer the same broom.
Even if I am of the same type: boosted macbook pro with ssd and memory beyond what is officially supported, I think integration of almost everything on one board skipping connectors, sockets, is more cost effective and more "green" overall.
Dies of silicons are packaged, socketed, etc instead every part of silicon will get closer in a package and will handle everything.
