The Evolution of GPUs: From Graphics to AI and Computing Powerhouse
In the past thirty years, the role of graphics processing units (GPUs) has dramatically evolved. Initially designed to assist with 2D shape rendering in early graphical user interfaces, GPUs have now become central to the computing industry, excelling far beyond their original scope. This journey of GPUs, from simple graphics facilitators to crucial components in high-performance computing and machine learning, marks a significant technological evolution.
The Era of CPU Dominance
Computing in the Late 1990s
The late 1990s witnessed a computing landscape dominated by central processing units (CPUs). High-performance tasks, whether in scientific research, data processing, or engineering, relied heavily on specialized processors or off-the-shelf chips from major companies like AMD, IBM, or Intel.

Case Study: ASCI Red Supercomputer
A prime example of this era's technology was the ASCI Red supercomputer. In 1997, it ranked among the most powerful computers, equipped with 9,632 Intel Pentium II Overdrive CPUs. Operating at 333 MHz, ASCI Red boasted a peak compute performance of over 3.2 TFLOPS (trillion floating-point operations per second).
The Importance of Floating Points
Floating points (or floats) represent non-integer values crucial for precision in science and engineering calculations. These differ from integers, which are whole values used in standard computer control and software operations. Understanding floats is key to grasping the computational capabilities and advancements of CPUs and later, GPUs.
