Perseus Labs tests the following CPU architecture.
IA-32 /x86
The term means Intel Architecture,
32-bit, which distinguishes it from the 16-bit versions of the
architecture that preceded it, and the 64-bit architecture IA-64 (which
is very different, although it has an IA-32 compatibility mode). The
more generic name for all 16 and 32-bit versions of this architecture
is x86.
x86 or 80x86 is the generic name of a microprocessor architecture first developed and manufactured by Intel.
The architecture is called x86
because the earliest processors in this family were identified only by
numbers ending in the sequence "86": the 8086, the 80186, the 80286,
the 386, and the 486. Because one cannot trademark numbers, Intel and
most of its competitors began to use trademarkable names such as
Pentium for subsequent generations of processors, but the earlier
naming scheme has stuck as a term for the entire family. The extended
version of the x86 architecture introduced with the 386 is called
x86-32 or IA-32, an abbreviation for Intel Architecture, 32-bit.
