B: hahaha! I told you that girl is a Pentium.

Get the PENTIUM mug.
A tragically underrated CPU made by Intel in the mid-1990s.

Sucessor of the Classic Pentium and predecessor of the Pentium II, the Pentium Pro brough fantastic levels of performance to the workstation and server markets.

These processors can be used in pairs... or in fours (Dual or quad processor configurations) for even higher performance.

Nowadays, these processors are quite affordable and are still defiant in their performance of everyday computing tasks, basic video editing, networked 3d rendering, or serving applications, as well as some light or classic gaming.

Best served with Windows NT 4, but also taste great with various Unix varieties.

Available in speeds up to 200MHz in a Socket 8 package.
Dude, this Pentium Pro system is really sweet!

A computer processor offed by Intell in several formats. Most Pentium 4s did manage to outpreform the competing AMD processors. However, at the Pentium 4 hit a wall at 4GHz (4 billion operations per second) and no faster proccesor could be made. The Pentium 4 line drew a lot of power and made alot of heat, preventing any Pentium 4 from being run over 4GHz without exream measures. Intel was forced to sell the last editions of the Pentium 4 with no speed increase, with only additional features to enhance the preformance. Intel's years of marketing the Pentium line as faster and therefore better finaly turned on them as the could increase the processes per second no further, and ironicaly lost buisiness to AMD processors which were able to be run at rates beyond those recomended by the manufacturer (overclocking).
In the summer of 2002 the 2.4 to 2.8 GHz Pentium 4 outpreformed AMD's Athlon. However by 2005 the Prescott Pentium 4 achitecture wasn't released in the planned 4GHz version, due to it LOSSING performance at sny higher speed due to delays in the on-chip memory chache. Intel introduced Pentium 4 as supposedly desinged for speeds up to 10GHz. This simpy never happened.

Intel's latest attempt to put one over on computer users, sacrificing real performance for high GHz numbers, in a (successful) effort to make people believe that they were getting a better processor.

Pentium 4s are charachterized by a locked multiplier, a heatspreader (which actually serves to drive temps higher) and a rediculously high price. Utterly owned by a good AMD Athlon.
My overclocked Athlon will pw33n j00're Pentium 4!!

A non-existant line of Intel's microprocessors intended to succeed the Pentium 4 line of microprocessors.

Pentium 4 processors codenamed Prescott (the first 1MB L2 cache ones) were supposed to be named Pentium 5, but they kept using the Pentium 4 name instead.
Prescott line of processors were intended to be named Pentium 5.
