Setting: Multicore-CPU is running an application which is only using one thread.
Assumption: In regards to clockspeed, 2-Core and 4-Core would need the same time to run and both would have the same TDP. (Same Generation and same manufacturer)
Would the Quadcore
- "produce" less heat?
- Cooling be more efficient?
Example 1: CPU usage per core with a quadcore (exemplary): core: c0 | c1 | c2 | c3 cycle0: 100% 0% 0% 0% cycle1: 0% 100% 0% 0% cycle2: 0% 0% 100% 0% cycle3: 0% 0% 0% 100% cycle4: 100% 0% 0% 0% cycle5: 0% 100% 0% 0% cycle6: 0% 0% 100% 0% cycle7: 0% 0% 0% 100%
Example 2: CPU usage per core with a dualcore (exemplary): core: c0 | c1 cycle0: 100% 0% cycle1: 0% 100% cycle2: 100% 0% cycle3: 0% 100% cycle4: 100% 0% cycle5: 0% 100% cycle6: 100% 0% cycle7: 0% 100%
My thought: Quadcore would have more unused "surface area" which would still be cooled.
