=== Developments in the first Multi-Core Processors core in server systems ===

The death In the early 2000's, the progress of single-core processors came at the time of the Pentium 4, whenprocessor development was starting to diminish. As mentioned above, they faced issues such as mentioned abovehigh power consumption, which also resulted in excessive heat and . There were many companies running power consumption became an issue. At this pointhungry servers, multi-core processors such as who wanted to lower the Pentium D were introducedcost of operations from electricity and cooling. HoweverThis is where IBM, Pentium D was not considered a “true” multi-core processor as what is considered top company in the workplace server market today by definition, due to its design of being two separate single-core dies placed beside each other in the same processor packagemade a big name for themselves.

The world's first true multi-core processor was called the POWER4In 2001, created in 2001 by IBM. It incorporated 2 physical cores on a single CPU die and implemented IBM's PowerPC 64-bit instruction set architecture (ISA). It was used in IBM's line of workstations, servers, and supercomputers at the time, namely the RS/6000 and AS/400 systems. === Multi core in server systems === Since multicore systems offered a lot of extra processing power compared first company to the output of release 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 for UNIX systems on the market, which became available on the market was . They called it the IBM POWER4 in 2001. It became highly successful , and gave IBM a very strong foothold in the industry when sold was released as part of their eServer lineup as the pSeries server, the IBM Regatta. Regatta was able to put IBM in the spotlight for data centers and large enterprises and was advertised as having "twice the performance for half the cost". 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 multi-core 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 dualiterations of their multi-core iterationsproducts, they had become a leader in the market with a share of 45 percent.

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 20152005, 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 the new product was still another large innovation in the industry by AMD, and a top competitor for the highest power CPU on the market.
