Logo from 1993 The latest standard badge design used by Intel to promote the Pentium brand. The Intel Pentium brand was a line of mainstream x86-architecture microprocessors from Intel. Processors branded Pentium Processor with MMX Technology (and referred to as Pentium MMX for brevity) are also listed here. It was replaced by the Intel ...
The Pentium (also referred to as the i586 or P5 Pentium) is a microprocessor introduced by Intel on March 22, 1993. It is the first CPU using the Pentium brand. [3] [4] Considered the fifth generation in the x86 (8086) compatible line of processors, [5] succeeding the i486, its implementation and microarchitecture was internally called P5.
[10] [11] The Pentium II was also the first P6-based CPU to implement the Intel MMX integer SIMD instruction set which had already been introduced on the Pentium MMX. [7] The Pentium II was a more consumer-oriented version of the Pentium Pro. It was cheaper to manufacture because of the separate, slower L2 cache memory.
Pentium II processor with MMX technology. MMX defines eight processor registers, named MM0 through MM7, and operations that operate on them.Each register is 64 bits wide and can be used to hold either 64-bit integers, or multiple smaller integers in a "packed" format: one instruction can then be applied to two 32-bit integers, four 16-bit integers, or eight 8-bit integers at once.
Socket 5 was created for the second generation of Intel P5 Pentium processors operating at speeds from 75 to 133 MHz [1] [2] as well as certain Pentium OverDrive and Pentium MMX processors with core voltage 3.3 V. It superseded the earlier Socket 4. It was released in March 1994. [3]
All models support: MMX L2 cache is off-die and runs at 50% CPU speed; The Pentium II OverDrive is a Deschutes Pentium II core packaged for Socket 8 operation. It comes with 512 KB of off-die full-speed L2 cache, which makes it very similar to the Pentium II Xeon.
Core i7, on the desktop platform no longer supports hyper-threading; instead, now higher-performing core i9s will support hyper-threading on both mobile and desktop platforms. Before 2007 and post-Kaby Lake, some Intel Pentium and Intel Atom (e.g. N270, N450) processors support hyper-threading. Celeron processors never supported it.
Pentium is a series of x86 architecture-compatible microprocessors produced by Intel from 1993 to 2023. The original Pentium was Intel's fifth generation processor, succeeding the i486; Pentium was Intel's flagship processor line for over a decade until the introduction of the Intel Core line in 2006.
