In the 2010s computers advanced at a snail's pace. Sometimes people got excited when chips were 10% faster from one year to the next.
However, this decade has been dramatically different and it has everything to do with the circuit sizes on those chips. My 2009 iMac that died had a 42-nanometer chip. My 2017 iMac has a 14-nanometer chip. My new mini-computer has a 4-nanometer chip and it is very powerful for something not much bigger than a Whopper sandwich.
In late 2019 both Microsoft and Sony released their latest generation of video game consoles using 7-nanometer chips. Since these have APUs with the graphics "card" built into the main processor, I wanted something like this in a computer. I waited almost 4 years to be able to get something similar in a mini-desktop PC.
These smaller circuits are not cheap to make The equipment to make them can cost billions. This is why Taiwan Semiconductor, which made the investment, is the number one manufacturer of these chips.
But it has resulted in a paradigm shift where people realize that they don't have to spend a fortune on graphics cards to play games. The APUs are not as good as a $1200 gaming PC, but they are good enough.
This also has resulted in hand-held gaming systems that are as powerful as a computer and can also be used as a computer when hooked up to a monitor, keyboard, and mouse.
Even the most recent iPhone can double as a gaming system.
Reportedly, Sony, Nintendo, and Microsoft are all coming out with more powerful gaming systems in the coming year. This has been an exciting decade for computer chips.
