Intel’s chief performance strategist wants the world to know that more cores doesn’t necessarily mean better performance. In his latest post on Medium, Ryan Shrout looked at the gaming performance of a Core i9-9900K CPU and found that there was little benefit of going above eight cores. The implication is that single thread is still king and that the high core count of chips such as the 16-core Ryzen 9 3950X doesn’t matter.
“Adding core count just because you can,” he concludes, “without a corresponding increase in sustained frequency and architectural design decisions necessary to feed these cores (like low latency memory systems), doesn’t result in better performance. The software engines that power games across the PC ecosystem scale best with frequency and IPC, and Intel plans to lead in this space for years to come.”
