Intel® Core™ i5-1155G7

The Intel Core i5-1155G7 is a laptop processor with 4 cores and 8 threads, built on the Tiger Lake architecture (10 nm process). It launched in Apr 2021. Clocks run from 2.5 GHz base to 4.5 GHz boost. A 8-MB L3 cache backs the cores (3.3 MB per core). It addresses DDR4, LPDDR4X memory up to 64 GB across 2 channels. The chip drops into the FCBGA1449 socket and exposes PCIe 4.0 (16 lanes). Rated TDP is 28 W. Notable platform capabilities: Gaussian Neural Accelerator, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core i5-1155G7 scores 2,776 in single-core performance and 9,571 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 5,155 for overall performance, 10,108 for productivity performance, 10,261 for creator performance, 9,212 for engineering performance and 10,721 for gaming performance. Its multi-core throughput works out to 2,393 per core, 1,196 per thread and 342 per watt. Its computed efficiency index is 974. Its performance index is 64, so its overall performance is 36% 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 i5-1155G7 scores 34,426 in integer math, 20,018 in floating-point math, 104,480 in compression, 5,318 in cryptography, 557 in physics simulation, 7,097 in vector SIMD, 37 in the prime sieve and 12,459 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 42% below in integer math, 56% below in floating-point math, 54% below in compression, 54% below in cryptography, 49% below in physics simulation, 54% below in vector SIMD, 45% below in the prime sieve and 45% below 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 i5-1155G7 has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 2.50 GHz and boosts up to 4.50 GHz.

After an audit, 2 values were corrected and 1 empty field was filled on the Intel Core i5-1155G7 record. Each change is listed with its old value, new value, rule and sources.

• Base clock: 1,000 MHz → 2,500 MHz. Rule: Base clock was the configurable-TDP-down figure. stored 1000 MHz is the cTDP-down end of the Wikipedia base range 1000-2500 MHz; PassMark base 2500 MHz = the nominal (high-TDP) base.
