So sánh core i7 8750h vs i7 9750h năm 2024

The Intel Core i7-9750H is a high-end processor for laptops with six cores based on the Coffee Lake architecture (2019 refresh, CFL-HR). The processor clocks at between 2.6 and 4.5 GHz (4 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the predecessor, the Core i7-8750H, the 9750H offers improved clock rates and a larger L3 cache.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now max. eight cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

Multi-thread performance is most comparable to the Intel Core i9-8950HK, an expensive hexa-core processor of the previous generation. While performance gains over the outgoing 8th Gen H-class chips are unimpressive to say the least, the average Core i7-9750H in our database is much faster than the Ryzen 7 3750H and other H-class Ryzen chips AMD sells as of mid 2019.

Thanks to its decent cooling solution and a long-term power limit of around 70 W, the Walmart EVOO Gaming 17 is among the fastest laptops powered by the 9750H that we know of. It can be 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

The integrated Intel UHD Graphics 630 is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz compared to the UHD 630 of the 8750H CPU. The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power consumption

This Core i7 series chip has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop makers are allowed to reduce slightly, 35 W being the lowest Intel-recommended value. Doing so would result in lower clock speeds and lower performance. Either way, a proper cooling solution is a must for a CPU like this.

The hexa-core Intel CPU is made with one of the old 14 nm Intel processes for below average, as of late 2022, energy efficiency.

Intel Core i7-8750H

► remove from comparison

The Intel Core i7-8750H is a high-end processor for laptops with six cores based on the Coffee Lake architecture and will be announced early 2018. The processor clocks at between 2.2 and 4.1 GHz (4 GHz with 4 cores, 3.9 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

Due to the two additional cores, performance has increased by almost 50% compared to a similar clocked Kaby Lake processor like the Core i7-7820HQ (2.9 - 3.9 GHz). Single-core performance has not improved since its Kaby Lake predecessor. As a high-end model, the i7-8850H is suitable for the most demanding applications and games.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz (rumored). The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i7 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.
