Intel Core i5-11400
Rocket Lake's budget six-core: Cypress Cove cores give it a large IPC jump over the i5-10400 at the same price, and it adds CPU-provided PCIe 4.0. Its real performance depends on the board, since B560 and Z590 let you lift the 65 W power limit that otherwise holds it back.
Pros
- Roughly 15–20% higher per-core performance than the i5-10400 at the same launch price
- PCIe 4.0 with 20 CPU lanes — x16 for the GPU plus a Gen4 NVMe slot
- Official DDR4-3200 support, and B560 boards finally allow memory overclocking
- Boxed Intel cooler included
- UHD Graphics 730 for display output and QuickSync encoding
Cons
- Locked multiplier — only power limits and memory can be tuned
- 2.6 GHz base; on a board that enforces 65 W PL1 the sustained multi-thread result drops sharply
- Six cores and 12 MB L3 is modest for heavy productivity work
- Runs hot and draws up to 154 W once the power limit is lifted
