Well this applies to everything then. Why buy the latest AMD or Intel CPU or Nvidia GPU ?
Some people upgrade from iPhone X to 15 this year because it’s cheaper. Some have an old iPhone and just want the latest model to go for 6 or 7 more years.
Even incremental upgrades like this year are welcome. Before there was an S model every other year. This year it’s the « iPhone 15S pro ». Slightly better and more powerful. The other thing is, I think it’s pretty hard to say « well last year model was good enough, we’ll go on a 2 year cycle this time ». It could send the wrong message to investors so they’re trapped in the race maybe ?
Usually because there’s some advantage — you actually need/want the performance offered by Zen4 over Zen3, you need four-cycle AXV512, you have a target framerate in a game, you need RTX or CUDA14… because if you don’t, obviously buying older and used saves you money and you don’t need the new stuff anyway.
