Intel Core i5-8600K vs Intel Core i7-11370H Comparison

The Intel Core i7-11370H and Intel Core i5-8600K represent two distinct Intel designs: a 10 nm Tiger Lake mobile processor and a 14 nm Coffee Lake desktop part. The recorded benchmark data shows the newer mobile chip winning seven of eight head-to-head tests, while the older desktop chip takes a single multi-threaded victory. This analysis breaks down the numbers, architecture, and specifications from the database.

Head-to-Head Benchmarks

The i7-11370H dominates the Cinebench suite. In Cinebench R15 single-core, it scores 139 against 122, a 13.9% advantage. Its multi-core result is 987 versus 867, a 13.8% lead. The R20 and R23 tests show consistent 13.7% deltas in both single and multi-core: R20 single 580 vs 510, multi 4113 vs 3616; R23 single 1382 vs 1215, multi 9793 vs 8611. Geekbench single-core also goes to the i7-11370H, 1667 vs 1514, a 10.1% edge.

The only win for the i5-8600K is Geekbench multi-core, where it scores 5997 against 5485, an 8.5% advantage. That result is notable because the i5 has six physical cores but no hyperthreading, while the i7 has four cores with eight threads. The i7's higher boost clock (4.80 GHz vs 4.30 GHz) and newer architecture likely explain its single-thread dominance, while the i5's extra two cores help in that specific Geekbench multi-threaded workload. Across all eight tests, the i7-11370H wins seven, with margins ranging from 10.1% to 13.9%.

Where Each One Wins

The i7-11370H wins all Cinebench tests (R15, R20, R23) in both single and multi-core, plus Geekbench single-core. That makes it the stronger choice for single-threaded workloads and for most multi-threaded rendering tasks in the Cinebench suite. The i5-8600K wins Geekbench multi-core, indicating an advantage in that specific test, likely due to its two additional physical cores. The i7 also has higher memory bandwidth (51.2 vs 42.7 GB/s) and PCIe Gen 4 versus Gen 3, which are recorded differences that could benefit memory-intensive and I/O-heavy tasks, though the data does not directly measure those. The i5's unlocked multiplier offers overclocking headroom, but the recorded benchmarks are at stock settings. For mobile use, the i7 is the only option given its BGA socket and 28 W TDP; the i5 is a desktop part with a 95 W TDP. The i7's higher boost clock and larger L3 cache give it a clear edge in single-thread performance, while the i5's extra cores help in multi-threaded Geekbench. Overall, the i7-11370H is the better performer in the majority of recorded tests, with the i5-8600K retaining a single multi-threaded win.
