Intel® Core™ i7-10870H

The Intel Core i7-10870H is a laptop processor with 8 cores and 16 threads, built on the Comet Lake architecture (14 nm process). It launched in Jul 2020. Clocks run from 2.2 GHz base to 5.0 GHz boost. A 16-MB L3 cache backs the cores (2.3 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCBGA1440 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 45 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core i7-10870H scores 2,615 in single-core performance and 13,920 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,033 for overall performance, 12,709 for productivity performance, 12,363 for creator performance, 14,268 for engineering performance and 11,325 for gaming performance. Its multi-core throughput works out to 1,740 per core, 870 per thread and 309 per watt. Its computed efficiency index is 899. Its performance index is 75, so its overall performance is 25% 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 i7-10870H scores 51,311 in integer math, 32,368 in floating-point math, 213,775 in compression, 4,679 in cryptography, 723 in physics simulation, 13,412 in vector SIMD, 42 in the prime sieve and 27,193 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 13% below in integer math, 29% below in floating-point math, 6% below in compression, 59% below in cryptography, 34% below in physics simulation, 14% below in vector SIMD, 37% below in the prime sieve and 20% 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 i7-10870H has 8 physical cores and runs 16 logical threads. It runs 2 threads per core. It runs at a base clock of 2.20 GHz and boosts up to 5.00 GHz.
