Intel - Pentium comparison
Pentium (1993-97)
cpui_p.gif (12182 bytes)
Branch Prediction,
64-Bit Bus Interface,
Dual Processors,
8k data and 8k code cache
0.35 micron CMOS technology

Pentium MMX (1997-98)

First chip with MMX. The Pentium replacement.

Pentium Pro [P6] (1995-97)

High-end, non-MMX chip is very fast with 32 bit code, unimpressive with 16 bit. Choice for servers and power users.
0.35 micron CMOS technology

Pentium II [P-II] (1997-)

MMX successor to Pentium Pro had better 16 bit performance, multimedia support.
Slot 1 Single Edge Contact (S.E.C.) cartridge where the core and L2 cache are surface mounted directly to a substrate and fully enclosed in a plastic and metal cartridge. L2 cache runs at half the processor speed.
0.35 micron CMOS technology
Pentium Celeron (1998-)
cpui_pc1.gif (9852 bytes)
Pentium Pro with MMX first versions without level 2 cache. (Cheaper version of PII). 0.25 micron CMOS technology. Mounted on a card with single edge processor package (S.E.P.P.).
(266MHz (no cache) and 300MHz (+ 128K L2 cache).
440EX AGPset.		 Xeon:
cpui_px1.gif (11807 bytes)
Successor to PII.
Slot 2 Single Edge Contact (S.E.C.) cartridge. 400MHz & 450 MHz. Min 512Kb cache.
Essentially a PII with a 100 MHz system bus located between the CPU & secondary cache chip(s), that run at the same speed as the processor.
440GX chip set or 450NX (supports up to four Xeon chips
Pentium III
 Pentium IV (Willamette): (2001 -)

Hyper pipelined technology doubles the pipeline depth to 20 stages, significantly increasing processor performance and frequency capability.
A rapid execution engine pushes the processor's Arithmetic Logic Units to twice the core frequency resulting in higher execution throughput and reduced latency of execution.
The 400 MHz system bus, the improved Advanced Dynamic Execution, and an improved floating point pushes data efficiently through the pipeline for lifelike video, 3D graphics.
Streaming SIMD Extensions 2 (SSE2) extends MMX™ and SSE technology, and with the addition of 144 new instructions, the Pentium® 4 processor gives you the advanced technology to get the most out of today's and tomorrow's Internet experience.
