pentium    音标拼音: [p'ɛntiəm]
n. pentium5(P5)俗称586
n. Intel公司的

pentium5(P5)俗称586Intel公司的

{Intel}'s {superscalar} successor to the {486}.
It has two 32-bit 486-type integer {pipelines} with dependency
checking. It can execute a maximum of two instructions per
cycle. It does pipelined {floating-point} and performs
{branch prediction}. It has 16 {kilobytes} of on-chip
{cache}, a 64-bit memory interface, 8 32-bit general-purpose
{registers} and 8 80-bit {floating-point} registers. It is
built from 3.1 million transistors on a 262.4 mm^2 die with
~2.3 million transistors in the core logic. Its {clock rate}
is 66MHz, heat dissipation is 16W, integer performance is 64.5
{SPECint92}, {floating-point} performance 56.9 {SPECfp92}.

It is called "Pentium" because it is the fifth in the 80x86
line. It would have been called the 80586 had a US court not
ruled that you can't trademark a number.

The successors are the {Pentium Pro} and {Pentium II}.

The following Pentium variants all belong to "x86 Family 6",
as reported by "Microsoft Windows" when identifying the CPU:

Model Name
1 Pentium Pro
2 ?
3 Pentium II
4 ?
5, 6 Celeron or Pentium II
7 Pentium III
8 Celeron uPGA2 or Mobile Pentium III

A {floating-point division bug
(ftp://ftp.isi.edu/pub/carlton/pentium/FAQ)} was discovered in
October 1994.
