Die shots of as many CPUs and other interesting chips as possible

Nice
I have on my desk the book "State of the Art" by Stan Augarten. It shows the progression of transistors and integrated circuits from conception through 1983.
The book was one of the inspirations for me to become an electrical engineer. My older brother loaned me a copy of it when it was published in 1983.

A nice collection of die shots is on Fritzchens Fritz [1] on flickr

If you're into this, and enjoy more details, many more get published weekly on Mastodon under the #nakeddiefriday tag - https://infosec.exchange/tags/nakeddiefriday

Which one of the CPUs do you think looks the cleanest, aesthetically? The first Alpha looks rather chaotic, while the Samsung Alpha looks very uniform. That TI PA-7000 FPC looks like chaos. I think the two PowerPCs look the best, which is what I'd expect too. Well, actually I'd expect some of the other RISC to look simpler too...

I do not know enough to analyse these chips in any meaninful way, but is there a trend or cool feature to be seen across?

Someone should sponsor that guy a gigapixel microscope such as those

Realistically, are these enough to replicate the chips?
dan_hawkins
Absolutely not. It's like opening a hood of your car, taking picture of what you see and then try to build replica of the engine based on that.

To capture the individual transistors on a modern CPU, you'd need an image tens of terabytes in size, and it'd have to be captured by an electron microscope, not an optical image. And even that wouldn't let you see all the layers. Some of the very old CPUs, I'm not sure what resolution would be required.

Mostly no. You do not see the lower layers and for anything sub 1um or so the resolution is too poor anyway.

Are there any shots of audio amplifiers?

Another great resource is this site: https://misdake.github.io/ChipAnnotationViewer/?map=Zeppelin... It has a Google Maps like interface for exploring die shots and even some annotated versions of chips.
I'm always fascinated by how brilliant us humans can be. So much so that we can put billions of transistors in very small spaces and in complex structures while also mass producing it.
I highly recommend watching this video about lithography and the machine that makes it all possible [1].
