11th Gen Intel Core i5 11400 Review
The 11th Gen Intel Core i5 11400 is a 6-core, 12-thread mainstream desktop processor, running a 2.6 GHz base clock that boosts to 4.4 GHz within a 65 Watt TDP on the LGA 1200 socket.
Unlike the earlier Comet Lake i5 10400, this chip uses genuinely newer 10nm SuperFin process technology despite carrying the Rocket Lake generation name, giving it real per-core efficiency gains over its 14nm predecessor.
Integrated Graphics
The standard non-F variant includes basic Intel integrated graphics for display output; buyers should confirm specific SKU details before assuming availability.
How Is the Core i5 11400 in Terms of Performance
The 6-core, 12-thread layout with genuine Rocket Lake architectural improvements gives this chip meaningfully better per-core performance than the previous-generation i5 10400 at a similar price point.
Benchmarks
Cinebench R23 multi-core scores of 10,313 and single-core scores of 1,408 comfortably lead the older i5 10400's reference sibling i5-10400F score of 7,617, directly reflecting Rocket Lake's architectural gains. Geekbench 5 multi-core scores of 6,583 confirm genuinely strong mainstream desktop performance.
