Our first Core i7-8750H benchmarks are in and it's 50 percent faster than the Core i7-7700HQ

Intel's vaunted hexa-core Coffee Lake-H platform is shipping to notebooks this month and preliminary results are promising. Test runs on the second-generation Gigabyte Aero 15X and Asus Zephyrus GM501 equipped with the same hexa-core Core i7-8750H CPU show a performance leap of up to 60 percent over the quad-core Core i7-7700HQ in multi-threaded workloads according to CineBench R15. The performance benefits mirror that of Kaby Lake-R vs. U-Series Kaby Lake where the quad-core Core i7-8550U can perform up to 50 percent faster than the dual-core Core i7-7500U that it replaces due largely to the doubled core count.

As with most Ultrabooks and gaming notebooks, however, the same CPU across multiple notebooks is very likely to perform slower or faster depending on the cooling potential of the chassis. In this case, the Aero 15X is slightly better at maintaining higher clock rates than the Zephyrus GM501 for slightly higher sustained scores (1110 vs. 1050 points) when looping the CineBench R15 Multi-Thread benchmark. The difference is only within single-digits and users are very unlikely to notice in practice, but the results are consistent nonetheless. Our MSI GS65 test sample in particular scores 17 percent slower than the GM501 in the same CineBench R15 benchmark to suggest far poorer Turbo Boost performance.

Single-core results from the new Core i7 CPU are much less impressive at only about 10 percent above the average Core i7-7700HQ. It's unsurprising to find that Intel is boasting its latest generation of processors for multi-tasking, content creators, and streamers as these types of workloads will benefit the most from the higher number of simultaneous threads.

Expect more reviews on Coffee Lake-H notebooks in the coming weeks along with the Core i9-8950HK MSI GT75 soon. Our more detailed overview of Intel's mobile Coffee Lake family can be found here.
