At this landmark event when the microprocessor turns 50, we asked leaders at major microprocessor companies to reflect on this remarkable achievement, their favorite processor, coolest features of microprocessors, or their special personal microprocessor memories. Please read on to find what NVIDIA, Intel, AMD, ARM, and TSMC leaders have to say. The year 2021 marks the 50th Anniversary of the 4004 chip. Few tech companies can even fathom reaching such a milestone. From a 4-bit CPU that clocked a whopping 740 kilohertz, capable of executing 92,000 instructions per second and accessing 4 KB of program memory and 640 bytes of RAM to a chip with two to eight cores, a 4.8-GHz CPU clock rate that can cache up to 12 MB, a quad-channel 3,200-MHz memory and high-definition immersive graphics.
