Overview
SummaryThe Intel Core i5-11600KF is a desktop processor with 6 cores and 12 threads, built on the Rocket Lake architecture (14 nm process). It launched in Jan 2021. Clocks run from 3.9 GHz base to 4.9 GHz boost. A 12-MB L3 cache backs the cores (2.6 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCLGA1200 socket and exposes PCIe 4.0 (20 lanes). Rated TDP is 125 W. Notable platform capabilities: Gaussian Neural Accelerator, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).
Performance
12 metricsThe Intel Core i5-11600KF scores 3,326 in single-core performance and 19,394 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,031 for overall performance, 17,263 for productivity performance, 16,654 for creator performance, 19,273 for engineering performance and 14,827 for gaming performance. Its multi-core throughput works out to 3,232 per core, 1,616 per thread and 155 per watt. Its computed efficiency index is 718. Its performance index is 100, equal to the Intel Core i5-12400. Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.
How these scores are computed
Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.
- Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
- Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
- Creator performance is 0.55 times multi-core plus 1.8 times single-core.
- Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
- Gaming performance is 3 times single-core plus 0.25 times multi-core.
- Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
- The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
- The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
Workload Benchmarks
8 workloadsScores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.
