Intel Core i9-11900
Intel's locked 65 W Rocket Lake desktop processor for LGA1200: 8 cores and 16 threads on a 14 nm process, 2.5 GHz base clock and up to 5.2 GHz boost, 16 MB cache, PCIe 4.0, DDR4-3200 and Intel UHD Graphics 750, launched in March 2021.
Pros
- 8 cores and 16 threads with boost up to 5.2 GHz
- 65 W base power rating, well below the 125 W of the Core i9-11900K
- PCIe 4.0 support with 20 CPU lanes
- Integrated Intel UHD Graphics 750 for display output without a discrete card
Cons
- Locked multiplier, so no overclocking unlike the K-series chips
- The 5.2 GHz peak is a Thermal Velocity Boost clock that Intel specifies only at or below 70 C
- Only 8 cores, fewer than the 10-core Core i9-10900 of the previous generation
- Requires an LGA1200 motherboard, a socket Intel replaced with LGA1700 for the next generation
