Wikipedia lists over 45 different Instruction Set Architectures.
I would bet that most of those are listed for legacy purposes, but I barely have any knowledge on the subject (I'm not even sure if ISAs directly correspond to architectures as in, e.g., amd64). It seems to be a topic "beyond my scope", and I have to Google the architecture for whatever device I'm dealing with, every single time.
Usually, I'm dealing with laptops and PCs (sometimes running Windows, sometimes OMV, which is based on Debian), Android devices (mostly smartphones), RaspberryPIs, and perhaps other SBCs in the future.
While I often see stuff such as ARM, ARMv7 ARMv8, x64, amd64, AArch64 and a few others, my research so far showed that many of them are references to a subset/family of architectures, so I end up wasting a lot of time to finally find that the answer was actually very simple.
I think I use this information almost exclusively for downloading the correct release of some software for my device (specially considering I'm only a beginner in using Docker).
Up until I started looking for this information, I didn't even know there was such a thing as RAM Architectures (per this question), so, if possible and relevant, I would appreciate any information on that as well!
Finally, I know that my question is derivative from this one and perhaps even others, but I felt like neither question I mentioned was aimed at what I this one intends to, as those and others are specific to some application of this concept (and often on StackOverflow)!
Edit: I believe I might have phrased my question incorrectly. With "the CPU architectures for the most common general purpose devices", I intended to ask for a summary of common architectures per "platform", such as:
| Platform | Main architecture(s) | AKA | Included in/similar to |
|---|---|---|---|
Android | arm64-v8a | ? | ? |
armeabi | ? | ? | |
armeabi-v7a | ? | ? | |
x86_64 | x64 (?) | ? | |
x86 | - | Included in x86_64 | |
Windows | x64 | amd64 | Included in AMD Instruction Set, Similar to Intel Instruction Set |
ARM A64 | AArch64, ARM64 | Included in Intel Instruction Set, Similar to AMD Instruction Set | |
Linux | (on a PC/laptop, is it even different from Windows?) | ||
RaspberryPi | |||
... | (is there anything else relevant for personal use?) |
... and so on.
(Everything on the above table is based on @pjc50's answer and @Sarthak Mishra's answer to this question).
I don't know if this table should be shorter or longer, since I'm asking for a list of relevant items, although I don't even know how many architectures (relevant or not) are there. For this, I apologize if I'm asking way too much!
