== How multicore multi core products were marketed == === Multi core in server systems ===
Since multicore systems offered a lot of extra processing power compared to the output of a single core processor, many companies were leaping at the opportunity to gain more power for their servers at the time. To capitalize on this, IBM started development of the first dual-core processor on the market, which became available on the market was the IBM POWER4 in 2001. It became highly successful and gave IBM a very strong foothold in the industry when sold as part of their eServer pSeries server, the IBM Regatta. They iterated more on the POWER series of processors, and in 2010, expanded the number of cores available from 2 to 8 with the release of the POWER7.

The invention and implementation of multicore was crucial to IBM’s success as we see today. During the development of the POWER4 in the mid 90s, IBM had a market share of 15 percent, with other companies such as Sun and HP taking a large percentage of the market. By 2010, with the release of multiple dual-core iterations, they had become a leader in the market with a share of 45 percent.
“The analyst community told us it literally blew their socks off. In a very short time we went from last place to industry leader.” – Carrie Altieri, vice president of communications for IBM’s Systems Technology Group
=== Desktop multi core systems ===
While IBM was dominating the market for server CPUs, there was still a hole in the market for integrating multicore into desktop computers. In may of 2015, AMD was the first company to release a dual-core desktop CPU, the Athlon 64 x2. With the cheapest in the line being $500 and the most powerful being $1000, It did not quite match IBM’s “twice the performance for half the cost”. However, they were still another large innovation in the industry by AMD, and a top competitor for the highest power CPU on the market.
