README
Modern CPUs are very complex beasts and there are so much information about them across different departments , therefore they can be overwhelming.
Microarchitecture cheat sheet aims to provide an organised collection of overviews about X86 CPUs that developers shall have on their mind when thinking about performance :
Last update date : 09 Mar, 2025
It divides that huge subject into following realms :
- Pipeline realm
- Arithmetic realm
- Branch prediction realm
- Load store realm
- Cache memory realm
- System memory realm
- Virtual memory realm
- Multicore realm
- MultiCPU realm
- "Across realms" realm
