In 1971 Intel created the first microprocessor, this microprocessor contained as much power as the most powerful computer in the world at the time. This processor was called Intel 4004. One year later the 4004 microprocessor was replaced by the twice as powerful 8008 microprocessor. In 1974 Intel released the 8080 processor, this was followed by the release of the 8085 and 8086 processors which were released between 1976 and 1978. The 8085 processor was a 8 bit microprocessor with a 64KB RAM and it was single voltage with 256 I/O ports. The 8086 processor was a 16 bit microprocessor with a 16 bit data bus, 1MB RAM and 64K I/O Ports. Since the first inception of microprocessors Intel has gone on to create better and more powerful processors. In 1979 Intel released the 8088 processor. The 8088 was the very first processor to be used in the original IBM PC and XT personal computers. The 8088 was less cheaper than the 8086 because of the availability of 8-bit data bus supporting chips which were less expensive. Even though the 8088 was slower than the 8086 IBM decided to choose the 8088 for their IBM PC. The 8088 was available in speeds from 4.77MHz and 8MHz, it also used a 16-bit architecture and supported up to 1MB of RAM. In 1979 Motorola created their own processor, they called it the 6860. The 6860 was chosen by Apple for their Macintosh computer. In 1980 Intel released the 80186 processor. Buyers could choose from CHMOS (Complementary High Performance Metal Oxide Semiconductor) or HMOS (High-performance Metal Oxide Semiconductor) and 8 or 16-bit versions. The CHMOS chip was able to run at twice the clock speed and one fourth of the power of the HMOS chip. Both chips came with a 1-micron core design and they both ran at 25MHz. ... ... middle of paper ... ...unched in October 2011, the first products were FX-Series desktop microprocessors which were then followed by Opteron 4200 and 6200 server CPUs that were launched in November 2011. According to Joel Hruska of the ExtremeTech website the AMD Bulldozer’s performance was significantly worse than anyone expected. The Bulldozer leverages features of multi-threading to combine the functions of what would usually be two separate cores into one package. AMD calls this combination module. Each module contains two cores. When AMD designed the Bulldozer it was aiming to have higher frequencies whilst still maintaining the same instructions per clock cycle (IPC) as the previous processor. The main issue with this processor was the way AMD implemented the Turbo Core. The Turbo Core was meant to increase the max clock speed by two grades when only four of the cores are enabled.
