Installing FreeBSD requires at least 64MB of RAM and 1.5GB of free hard drive space. However, this is only a minimal installation, so there is almost no free space left after installation. RAM requirements vary depending on usage. Dedicated FreeBSD systems can run at least 128MB of RAM while desktop systems only have at least 4GB of RAM.

The processor requirements for each structure can be summarized as follows:

amd64

This is the most common type of processor on desktop and laptop computers, also known as x86-64 architecture.

There are two main suppliers of amd64 processors: Intel® (making Intel64 processor) and AMD (manufacturing AMD64).

Examples of amd64 compatible processors: AMD Athlon ™ 64, AMD Opteron ™, multi-core Intel® Xeon ™, Intel® Core ™ 2 and newer processors.

i386

This architecture is 32 bit x86 architecture. Almost all floating point i386-compatible processors and all Intel 486 and above processors are supported.

FreeBSD will take advantage of Physical Address Extensions (PAE) on CPUs that support this feature. If unknown, PAE is a memory management feature for the x86 architecture that allows the CPU to directly access physical memory more than 4GB. Multiplying PAE with the feature enabled will erase memory above 4GB and allow the system to use it. This feature controls device drivers and other features of FreeBSD that are used.

ia64

The currently supported processors are Itanium® and Itanium® 2. Supported chipsets include HP zx1, Intel® 460GX and Intel® E8870. Both single processor configuration (Uniprocessor - UP) and symmetric multi-processor (Symmetric Multi-processor - SMP) are supported.

pc98

How the following hardware is supported:

NEC PC-9801/9821 series with almost all i386 compatible processors, including 80486, Pentium®, Pentium® Pro and Pentium® II
All compatible i386 processors from AMD, Cyrix, IBM and IDT
Epson PC-386/486/586 Series, compatible with NEC PC-9801 series
NEC FC-9801/9821 and NEC SV-98 series

Unsupported hardware:

High resolution mode
NEC PC-98XA / XL / RL / XL ^ 2 and NEC PC-H98 series are only supported in normal mode (PC-9801 compatible)
FreeBSD and Bus New Extend Standard Architecture SMP related features (NESA) are used in PC-H98, SV-H98 and FC-H98 series

Powerpc

All Apple® Mac® New World ROM systems with integrated USB are supported. SMP is supported on machines with multiple CPUs.

A 32-bit kernel can only use the first 2GB of RAM.

sparc64

Supported FreeBSD / sparc64 systems are listed at the FreeBSD / sparc64 project.

SMP is supported on all systems with more than 1 processor. A dedicated disk is required because it cannot be shared with another operating system during installation.
