Linux Mint is available in different versions and a 64-bit as well as a 32-bit variant. For Linux Mint 20.3 from 2022, a RAM of 1,024 MB and 15 GB on the hard disk are required in the 64-bit version. However, 2,028 MB of RAM and 20 GB are recommended for smooth operation. The 32-bit version gets by with 512 MB and 9 GB of hard disk space. However, a more generous approach is recommended here as well: Linux Mint itself estimates 1,024 MB of RAM and a hard drive of at least 20 GB for this. Processors without Physical Address Extension (PAE) are also not supported.
For 2020 Linux Mint Debian Edition (LMDE), your computer needs at least 1 GB of RAM and 15 GB of hard disk space, but 2 GB and 20 GB are recommended. These requirements apply equally to 64-bit and 32-bit. Processors without PAE are also fully supported in LMDE. All requirements apply to versions with the MATE or Cinnamon desktop environments.
