Intel Core i9-11900KF
Intel's unlocked Rocket Lake flagship without integrated graphics for LGA1200: 8 cores and 16 threads on a 14 nm process, 3.5 GHz base clock and up to 5.3 GHz boost, 16 MB cache, PCIe 4.0 and DDR4-3200, launched in March 2021 as the KF version of the Core i9-11900K.
Pros
- 8 cores and 16 threads with boost up to 5.3 GHz
- Unlocked multiplier for overclocking on supported LGA1200 boards
- PCIe 4.0 support with 20 CPU lanes
- Launch price of $513, $26 below the Core i9-11900K, with the same cores and clocks
Cons
- No integrated graphics, so a discrete graphics card is required for display output
- Rated at 125 W at base clock, but power draw during boost can be considerably higher
- Only 8 cores, fewer than the 10-core Core i9-10900KF of the previous generation
- Requires an LGA1200 motherboard, a socket Intel replaced with LGA1700 for the next generation
