The i9-11900K is a somewhat confusing component. On the one hand, it compares unfavorably with its own predecessor, the i9-10900K: it has 8 cores (down from its older sibling’s 10), yet has the same top speed. And indeed, benchmarks by Gamers Nexus show that performance is very similar, with the i9-11900K sometimes slightly behind its predecessor.
On the other hand, 8 cores (and 16 threads) is likely to be more than enough for the vast majority of both gaming and workstation users, 5.3 GHz is still an excellent native top speed, and the two fewer cores do make a slight positive difference in favor of cooler temperatures on the 11900K. Thus, although the core count has been ‘downgraded,’ this i9 remains a powerful processor.
