Multi-core Processor
The shift to multi-core chips transformed computing speed by running tasks in parallel
7 days ago
0
What was the primary constraint that led to the development of multi-core processors instead of simply increasing CPU clock speeds?
Multi-core processors were developed solely to reduce manufacturing costs by combining CPUs.
Increasing clock speed was unlimited, but multi-core processors were created to simplify software development.
Physical and thermal limits prevented further increases in clock frequency, prompting the shift to multiple cores for parallel processing.
