Apple's Silicon Magic Is Over!

Chips are reaching the physical limits of what is possible. According to a video I watched today, an experimental 1 nm process only has 1 atom per transistor. That doesn't sound right to me, but if true, then you can't go smaller than that.

There might still be some room for improvement, but smaller circuits tend to fail because quantum effects cause electrons to jump between circuits.

Someday computers might have circuits that use light instead of electricity, but right now the technology is not even close.

What would it mean if computers can't get much faster? If you need more computing power then you would need more chips, or bigger ones, that either way consume more energy.

However, it feels like computers are plenty powerful right now. It is not like the general public has a strong need for more powerful chips.

Apple already has good competition from AMD. My mini computer is twice as powerful as the Apple M2 chip.

A Look Inside Apple's $130 USB-C Cable

Apple sells things at a higher margin than other companies.  Although this is a superior cable for data transmission, maybe competitors will offer comparable products.

Your Internet is Too Fast

It was costing me around $90 a month for gigabit Internet service.  So I downgraded to 200 Mbit, for about $35 per month, and it is plenty fast for me.

Exciting Decade for Computer Chips

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.

Best wishes,

Who The Hell Asked For A PS5 Pro?

I've been saying the same thing.  I also bought a powerful mini-PC that can play games.  All of this change, including the consoles and the handhelds, has happened because of AMD's new powerful energy-efficient chips.  Intel has chips too, but they are not quite as good.

The PS5 and the XBox Series X consoles are 10.28 and 12 teraflop machines respectively.  That is still a great deal of performance and you would have to spend a lot on a PC to match that.

Apple is also starting to push gaming on the most expensive iPhones.

I have no faith in Cloud Gaming, but this may eventually be the future where you can run triple-A games on any device with a screen.

USB-C Tutorial for Everybody

The bottom line is that when buying a USB-C cable, make sure that it supports the data speed that you want.  The same thing applies to power delivery for fast charging.

Using Apple Vision Pro: What It’s Actually Like!

I find this interesting. I can't imagine it being more than a novelty for now. For it to be anything more than a novelty, it is going to have to immerse you into another world.
