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.
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.
Intel's second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions. P5 original Pentium microprocessors, first x86 processor with super-scalar architecture and branch prediction. P6
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.
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.
However, its L2 cache subsystem was a downgrade when compared to the Pentium Pro's. In 1998, Intel stratified the Pentium II family by releasing the Pentium II-based Celeron line of processors for low-end computers and the Intel Pentium II Xeon line for servers and workstations. The Celeron was characterized by a reduced or omitted (in some ...
The Pentium Dual-Core brand was used for mainstream x86-architecture microprocessors from Intel from 2006 to 2009, when it was renamed to Pentium.The processors are based on either the 32-bit Yonah or (with quite different microarchitectures) 64-bit Merom-2M, Allendale, and Wolfdale-3M core, targeted at mobile or desktop computers.
The Pentium 4 was a seventh-generation CPU from Intel targeted at the consumer and enterprise markets. It is based on the NetBurst microarchitecture. Desktop processors
