Why to buy 11400F processor instead 11400 ? I notice now that 11400F havn't iGPU. My brother buy to me this.
i5 11400f it's cheaper because it doesn't include the iGPU. That's it. If you need the iGPU processing power or onboard video outputs, you need a non-F intel CPU.
The only issue with no IGP is that there is a chance that troubleshooting systems issues related to video can be harder or impossible. It is unlikely that a typical user will ever run into this potential issue.
