Intel® Core™ i7-11800H

The Intel Core i7-11800H is a laptop processor with 8 cores and 16 threads, built on the Tiger Lake architecture (10 nm process). It launched in Apr 2021. Clocks run from 2.3 GHz base to 4.6 GHz boost. A 24-MB L3 cache backs the cores (4.3 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCBGA1787 socket and exposes PCIe 4.0 (20 lanes). Rated TDP is 35 W. Notable platform capabilities: Gaussian Neural Accelerator, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core i7-11800H scores 3,004 in single-core performance and 19,568 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,667 for overall performance, 16,925 for productivity performance, 16,170 for creator performance, 20,057 for engineering performance and 13,904 for gaming performance. Its multi-core throughput works out to 2,446 per core, 1,223 per thread and 559 per watt. Its computed efficiency index is 1,296. Its performance index is 95, so its overall performance is 5% below the Intel Core i5-12400 (index 100). 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.

Scores 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.

In the individual workload tests the Intel Core i7-11800H scores 70,145 in integer math, 41,637 in floating-point math, 233,405 in compression, 11,952 in cryptography, 917 in physics simulation, 15,642 in vector SIMD, 82 in the prime sieve and 27,931 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 19% above in integer math, 9% below in floating-point math, 2% above in compression, 4% above in cryptography, 16% below in physics simulation, 1% above in vector SIMD, 22% above in the prime sieve and 23% above in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Core i7-11800H has 8 physical cores and runs 16 logical threads. It runs 2 threads per core. It runs at a base clock of 2.30 GHz and boosts up to 4.60 GHz.

After an audit, 2 values were corrected and 1 empty field was filled on the Intel Core i7-11800H record. Each change is listed with its old value, new value, rule and sources.

• Base clock: 1,900 MHz → 2,300 MHz. Rule: Base clock was the configurable-TDP-down figure. stored 1900 MHz is the cTDP-down end of the Wikipedia base range 1900-2300 MHz; PassMark base 2300 MHz = the nominal (high-TDP) base.
