I'm looking for the minimum CPU requirements for Windows 7. Specifically, I want to know if it requires SSE, SSE2, etc.

Wikipedia states that SSE2 was a requirement for Windows 8, but it doesn't say anything about Windoes 7.

I found this here:

The minimum requirements for Windows 7 are modest by today's standards:

  • 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor
  • 1 GB RAM (32-bit) or 2 GB RAM (64-bit)
  • 16 GB available disk space (32-bit) or 20 GB (64-bit) -- just for the OS, not applications or data files
  • DirectX 9 graphics processor with Windows Display Driver Model (WDDM) 1.0 or higher
  • Internet access

Unfortunately, that doesn't say anything about specific CPU features required. Does anyone have the information?

    There were not special requirements. If it could run Windows XP it ran Windows 7. SSE2 is only required for Windows 8.1 and greater.

  • @Ramhound: so not even SSE is needed? No other CPU features (TSC, CMPXCHG8, CMOV) are required?

    If your machine runs Windows XP it will run Windows 7. If you want specific CPU requirements look at Windows Vista's requirements. Windows 7 was targeted to allow upgrades from Windows XP machines though.
