The whole point of negative PBO is to "make room" (in voltage) for more and longer-sustained overclocking, including via built-in mechanisms like Core Performance Boost (CPB). However, if you’re looking for a more cost-effective option that still delivers excellent performance, especially in single-threaded tasks, the i7-14700K could be the way to go. The o11 has space for 8 fans, whereas many popular "air flow" cases only usually have space for 6-7 fans. 1. /r/AMD is community run and does not represent AMD in any capacity unless specified.
