CPU Comparison
Intel Core i7-11700KF vs Intel Core i9-11900F
A side-by-side comparison of specs, performance and value. The Intel Core i7-11700KF is a high-performance desktop processor from the Rocket Lake-S generation, released in March 2021. It features 8 cores and 16 threads built on Intel's 14nm process. The 'K' signifies an unlocked multiplier for overclocking, while the 'F' indicates the absence of integrated graphics. Operating at a base clock of 3.6 GHz and boosting up to 5.0 GHz, it is designed for enthusiasts who prioritize raw frequency and tuning. With a TDP of 125W, it requires robust cooling. The processor includes 16 MB of L3 cache and supports 20 PCIe 4.0 lanes, ensuring maximum bandwidth for multiple GPUs and fast storage. The 11700KF caters to gamers and overclockers who want top-tier single-core speeds and multi-core grunt without paying for integrated graphics they won't use.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
8 cores at 5.0 GHz make short work of compilation and rendering tasks.
Good multi-threaded performance for creator workloads, though outpaced by newer 12-core and 14-core competitors in heavily parallel tasks.
Gaming
Outstanding gaming performance, easily pushing 240Hz+ in esports titles when paired with fast RAM and a high-end GPU.
Strong single-core performance ensures high frame rates in most titles, but it may trail newer, more efficient gaming CPUs in CPU-limited scenarios.
Virtualization
Strong core count and clock speeds provide excellent VM performance.
Capable for basic virtualization, but its 8 cores/16 threads may be limiting for professional workloads with many concurrent VMs.
Efficiency
The 14nm process at 125W+ is highly inefficient and generates massive heat under load.
The 14nm process leads to high power consumption and heat under load, requiring robust cooling and resulting in poor performance-per-watt versus modern 10nm or 5nm parts.
