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.
The Intel Celeron 5205U is a power efficient entry-level dual-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in October 2019. Compared to the similar Whiskey Lake Celeron 4205U processors, the difference is the higher clock speed (+100 MHz) and support for faster memory. The processor cores are clocked at only 1.9 GHz (no Turbo) and don't support SMT / HyperThreading (so only 2 threads). More information on Comet Lake and all the models and articles on it can be found here.
The integrated graphics adapter is still the same as in the previous generations. It is called only Intel UHD Graphics but is still the same Intel UHD Graphics 610 like in the Pentium 4205U. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel LPDDR3-2133/DDR4-2400 memory controller (compared to DDR4-2666 in the faster and costlier Core i3/i5/i7 processors).
Performance
While we have not tested a single system powered by the 5205U as of August 2023, it's safe to expect the chip to be about half as fast as the Core i3-10110U (Comet Lake, 2 cores, 4 threads, up to 4.1 GHz). Which is nothing to write home about, really, as of mid 2022.
Power consumption
This Celeron has a default TDP, also known as the long-term power limit, of 15 W. Intel officialy allows laptop manufacturers to reduce that value somewhat, 12.5 W being the lower limit, resulting in lower clock speeds and lower performance. Unlike most Comet Lake family processors, Celeron 5205U is fairly likely to actually stick to that limitation as its cores are not Boost-enabled.
Last but not the least, this CPU is manufactured on an old, as of late 2022, 14 nm Intel process making for subpar energy efficiency.
The Intel Core i5-8400H is a high-end processor for laptops with four cores based on the Coffee Lake architecture and will be announced early 2018. The processor clocks at between 2.5 and 4.2 GHz (4.1 with 4 cores) and can execute up to eight 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
The Intel Core i5-8400H should perform similar as the older Core i7-7920HQ (3.1 - 4.1 GHz). The faster Coffee Lake CPUs, like the Core i7-8750H offers two additional cores and is therefore up to 50% faster in multithreaded benchmarks. Still, the performance of the i5-8400H should be sufficient for even 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 i5 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.
