As always, Fedora continues to develop (http://www.fedoraproject.org/wiki/Red_Hat_contributions) and integrate the latest free and open source software (http://www.fedoraproject.org/wiki/Features). The following sections provide a brief overview of major changes from the last release of Fedora. For more details about other features that are included in Fedora 12 refer to their individual wiki pages that detail feature goals and progress:
1.2.1. Processor and memory requirements for PPC Architectures
CPU 至少為：PowerPC G3 / POWER3
Fedora 12 supports the New World generation of Apple Power Macintosh, shipped from circa 1999 onward. Although Old World machines should work, they require a special bootloader which is not included in the Fedora distribution. Fedora has also been installed and tested on POWER5 and POWER6 machines.
Fedora 12 supports pSeries and Cell Broadband Engine machines.
Fedora 12 also supports the Sony PlayStation 3 and Genesi Pegasos II and Efika.
Fedora 12 includes new hardware support for the P.A. Semiconductor 'Electra' machines.
Fedora 12 also includes support for Terrasoft Solutions powerstation workstations.
Recommended for text-mode: 233 MHz G3 or better, 128 MiB RAM.
Recommended for graphical: 400 MHz G3 or better, 256 MiB RAM.
1.2.2. Processor and memory requirements for x86 Architectures
The following CPU specifications are stated in terms of Intel processors. Other processors, such as those from AMD, Cyrix, and VIA that are compatible with and equivalent to the following Intel processors, may also be used with Fedora. Fedora 12 requires an Intel Pentium or better processor, and is optimized for Pentium 4 and later processors.
使用圖形化模式的系統建議：400 MHz Pentium II 或更新的處理器
Minimum RAM for text-mode: 128 MiB
Minimum RAM for graphical: 192 MiB
Recommended RAM for graphical: 256 MiB
1.2.3. Processor and memory requirements for x86_64 architectures
Minimum RAM for text-mode: 256 MiB
Minimum RAM for graphical: 384 MiB
Recommended RAM for graphical: 512 MiB
1.2.4. Hard disk space requirements for all architectures
The complete packages can occupy over 9 GB of disk space. Final size is entirely determined by the installing spin and the packages selected during installation. Additional disk space is required during installation to support the installation environment. This additional disk space corresponds to the size of /Fedora/base/stage2.img (on Installation Disc 1) plus the size of the files in /var/lib/rpm on the installed system.
