An equivalent CPU today if tested in the same manner, would give results of 300,000 to 800,000 instructions per second. The Pentium could crunch two instructions per clock cycle under the right conditions, but these had to come from the same thread.
It is challenging to grasp just how much more capable chips are now, primarily because the metrics used in the past are not particularly relevant today. Credit: Fritzchen Fritzīy the mid-1970s, Moore's Law continued unabated due to ongoing technological advances in the design and manufacturing of semiconductor integrated circuits. Its processing power was equally impressive, executing over 100 million instructions per second, thanks to its clever design and relatively high clock speed of 60 MHz. Intel's Pentium contained an astounding 3.1 million transistors within a chip just half of a square inch (294 mm2) in size. His prediction not only proved correct but also became an accurate model for many future decades.īy 1993, a premium PC boasted chips that were unimaginable thirty years earlier.
When Gordon Moore, director of R&D at Fairchild Semiconductor, wrote about trends in chip manufacturing in 1965, he speculated that an average processor could contain over 60,000 components within a decade. Getting more with Moore: Exponential growth Join us as we examine the PC's metamorphosis from awkward hulking beige boxes to an astonishing array of powerful, colorful, and astonishing computers. However, few could have predicted exactly how these developments would unfold. While some aspects have barely changed, others are unrecognizable when compared to machines of the past.Īnd of course, change is inevitable when billions of dollars of revenue are at stake.
The humble personal computer has been a part of our lives, directly or indirectly, for nearly five decades, but its most significant transformations have transpired over the last thirty years.ĭuring this time, the PC has utterly transformed in appearance, capability, and usage.
