Overview
SummaryThe Intel Core i7-8705G is a laptop processor with 4 cores and 8 threads, built on the Kaby Lake architecture (14 nm process). It launched in Jan 2018. Clocks run from 3.1 GHz base to 4.1 GHz boost. A 8-MB L3 cache backs the cores (2.3 MB per core). It addresses DDR4 memory up to 64 GB across 2 channels. The chip drops into the FCBGA2270 socket and exposes PCIe 3.0 (8 lanes). Rated TDP is 65 W. Notable platform capabilities: Extended Page Tables (EPT).
Performance
12 metricsThe Intel Core i7-8705G scores 2,188 in single-core performance and 7,608 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,080 for overall performance, 8,008 for productivity performance, 8,123 for creator performance, 7,323 for engineering performance and 8,466 for gaming performance. Its multi-core throughput works out to 1,902 per core, 951 per thread and 117 per watt. Its computed efficiency index is 506. Its performance index is 51, so its overall performance is 49% 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.
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.
