On this site you can read about thousands of processors models. And every year it is more and more difficult to write about some new (old) processors, since everything has been known for a long time. But there are also exceptions to the rule which we love to find. In 2021, I learned about one unusual processor, the information about which I want to share with you. The roots of this processor’s history go back to Italy, in the distant year or 1998. This time just falls on the confrontation between Intel and its second generation Pentium and AMD K6-2 and K6-3 processors. The Cyrix MII processors from Cyrix Corporation, IDT WinChip 2s and Rise mP6s were still going strong as well.

But before we talk about the Genesys B52 MMX processor, we should take a closer look at Intel Pentium II processors in general, as the Italian processor primarily owes its appearance to them.

From 1993 to 1997, the Pentium dominated all market segments. Over time, the name of the “Pentium” trademark even grew into a household name (Its all about the Pentiums baby), but with the release of the Pentium II, everything changed. If earlier Intel did not deeply segment the market, there were Pentium Pros for workstations and servers, and for everything else there were various models of Intel Pentium processors, in which, at the end of their domination, Intel added MMX instructions, depriving and thereby putting an end to its server segment. The new slot form factor of the processor, the abandonment of the usual pins and ceramics and further segmentation of the market (using Intel Celeron processors and the new Xeon line) radically changed the further course of development of the history of microprocessors.
