Frequently Asked Questions
The Intel Core i5-11400F Processor — 6 cores and 12 threads, 2.6 GHz base rising to 4.4 GHz with Turbo Boost, 12 MB Intel Smart Cache, 65 W processor base power, LGA1200. Supplied from stock with a 1-year warranty.
The budget gaming CPU of 2021
The i5-11400F is the 11400 with the integrated graphics disabled: six cores, twelve threads, 2.60/4.40 GHz, 12 MB of cache, 65 W. It became the default budget gaming CPU of 2021–2022 — Cypress Cove performance and PCIe 4.0 at a price that undercut everything around it.
A discrete graphics card is required to POST — the F-variant has no video output. With one fitted the processor is identical to the 11400, and its gaming performance sat close to CPUs costing far more, which is exactly why it sold in volume.

Which systems take this processor
Anything on the LGA1200 socket with an Intel 500 or 400 series chipset: H510, B560, Z590, plus Z490, H470, Q470 and W480 after a BIOS update. 11th Generation parts run natively on 500 series boards; Z490 and H470 boards take them after a BIOS update, while H410 and B460 boards do not support 11th Generation parts at all.
- Business desktops and SFF machines — Dell OptiPlex 3090 / 5090 / 7090, HP EliteDesk 800 G7 / ProDesk 600 G7, Lenovo ThinkCentre M70s / M90s. The 65 W envelope is what these chassis were designed around.
- Entry workstations — HP Z1 G8, Dell Precision 3650, Lenovo ThinkStation P350, where six cores with Hyper-Threading and PCIe 4.0 cover office, CAD and light simulation work.
- Micro-server and NAS builds — W480 and W580-class boards accept Core i5 parts with ECC UDIMMs; Rocket Lake added PCIe 4.0, which matters for NVMe-heavy builds.
One caveat when buying a board separately: 400 series boards need a BIOS update before an 11th Generation part will POST, and H410 / B460 boards do not support 11th Generation at all — check the board, not just the socket. Tell us the model and we will confirm before you order.
How it compares across the i5 line
| Processor | Cores / Threads | Base / Turbo | Cache | Power | Socket |
|---|---|---|---|---|---|
| i5-10400F | 6 / 12 | 2.90 / 4.30 GHz | 12 MB | 65 W | LGA1200 |
| i5-11400 | 6 / 12 | 2.60 / 4.40 GHz | 12 MB | 65 W | LGA1200 |
| i5-11400F | 6 / 12 | 2.60 / 4.40 GHz | 12 MB | 65 W | LGA1200 |
| i5-12400F | 6 / 12 | 2.50 / 4.40 GHz | 18 MB | 65 W | LGA1700 |
The 12400F is the Alder Lake successor on the newer LGA1700 socket: faster per core and DDR5-capable, but a platform change. On an existing LGA1200 board with a discrete card, the 11400F is the strongest drop-in.
How each processor is tested before it ships
- Visual inspection of the integrated heat spreader, substrate and contact pads; the sSpec laser marking (SRKP1 on our i5-11400F stock) is verified against the Intel specification sheet.
- Burn-in on a matched diagnostic board with a pair of memory modules of the correct type for this platform.
- All populated memory channels and the primary PCIe lanes are validated, then the processor is identified in the BIOS and in the operating system.
- A sustained multi-threaded load test at full core count, with the clock and thermal readings recorded.
- Thermal paste cleaned off, final inspection, then packaging in an anti-static tray with foam — which is how it arrives to you.
Warranty and lead time
Every processor is covered by a 1-year warranty against defects in workmanship and function. If a part fails within the period we replace it or refund it, and we cover return shipping on a verified fault. Stock is held in our own warehouse and normally dispatches within three to seven working days; tracking is issued at dispatch.
Purchasing and volume enquiries
The minimum order quantity for this processor is 2 units. Price is quotation-based rather than listed, because CPU pricing moves with each incoming batch — send us the quantity you need and we will come back with a firm quote and the current lead time. Larger quantities ship from the same production batch so the sSpec and the stepping stay consistent across your order.
