According to the tests conducted by engineers at Sandia National Laboratories, New Mexico, who have simulated future high-performance computers containing the 8-core, 16‑core, and 32-core microprocessors, it appears that after 8 cores put to process the more cores added the worse applications perform especially bad for data-intensive apps. As the chart below shows, while keep adding more cores to the tests the memory bandwidth remains flat, and that is the cause of the trouble.
