Our take on the Intel Core i9-11900K
The Intel Core i9-11900K is an unlocked processor for Intel 500 series and select 400 series boards, with PCIe Gen 4.0 support. It suits streamers upgrading an older Intel build. At a tracked $499 it sits at the bottom of a $499 to $549.08 range from August 9 to October 19, 2026.
The listing supports Turbo Boost Max Technology 3.0 and Intel Optane Memory. It states that no thermal solution is included, so a cooler is an extra cost. The packet gives no core count or clock speed, so check those before buying. Retailer rating is 4.6 across 1,624 ratings.
