Custom CPUs

“Google developing own CPUs for Chromebook laptops“.

Interesting to see that many years after Apple started creating their CPUs for the iPhone (and now laptops/desktops), so many companies are following. Google is not new to building their chips (TPU, Titan (used in security keys and as encryption module for servers/Pixel phones), and likely more), but quite new to more generalised computing CPU for phones and laptops.

And it makes sense — a lot of the generic CPUs were too generalist and not that great at their job (and are plagued with bugs). It came with heavy power usage. Having a ML/AI chip, a GPU chip, a generalist CPU chip (or two, one focussing on high performance, and one on efficiency, like the M1), one for security/encryption (Titan/T2), etc.

Curious to see how much of a head start Apple really has, and very eager to finally see some real innovation in the CPU space (sorry AMD with Ryzen: too little, too late).

Let’s see if Intel and AMD will be able to adapt and reinvent themselves and what it means for ARM (and the ARM IP issue in China), and if other architectures like MIPS are making a chance.
