I gave one unholy complaint to Intel when I got my new (old) computer home only to find it contained the "Pentagram 666" CPU which they claimed (falsely) that it actually ran at 667 MHz, exactly +1 more MHz than the mark of the devil. I called them a bunch of lying, demon wurshippin goat-horned deadites. At the time they were highly mixed up with Microsoft, which really IS an evil organization (this all happened in pre X-Box era, but if you ever look closely at an X-Box you will find it is actually a cross turned crooked -- shudder -- do NOT look closely at it! -- the 360 will make your head turn AROUND ON YOUR NECK).
Well anyway alls well that ends well, they eventually got hooked up with Apple & are quite saintly now. I even bought some Intel stock, see?
Its WURTHLESS.

Pentium is curently used by Intel as the brand for the low-end dual core processors.

"Pentium" was also the name of a horse.

Intel brought back the "Pentium" brand after demand from laptop makers.

The Pentium[1] brand refers to Intel's single-core x86 microprocessor[2] based on the P5 fifth-generation microarchitecture. The name Pentium was derived from the Greek pente (πέντε), meaning 'five', and the Latin ending -ium.
