The AMD Ryzen 7 3750H is a mobile SoC that was announced in January 2019. It combines four Zen+ cores [8 threads] clocked at 2.3 - 4 GHz with a Radeon RX Vega 10 graphics card with 10 CUs [640 Shaders] clocked at up to 1400 MHz. Compared to the similar Ryzen 7 3700U, the 3750H offers a 20 Watt higher TDP and therefore a better performance under long periods of load. The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.
Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS [performance per clock] improvements.
Performance
The average 3750H in our database is in the same league as the Core i7-10610U, as far as multi-thread benchmark scores are concerned. This is a fairly good result, as of early 2022.
The ROG Zephyrus G15 GA502DU is among the fastest laptops built around the 3750H that we know of. It can be about 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Ryzen 7 has a default TDP of 35 W [also known as the long-term power limit]. Laptop manufacturers are free to change that value to anything between 12 W and 35 W with clock speeds and performance changing accordingly. These values are comparatively high, making an active cooling solution pretty much a necessity.
Last but not the least, this AMD APU is built with a rather old, as of late 2022, 12 nm process for lower-than-average energy efficiency.
Intel Core i5-9300H
► remove from comparison
The Intel Core i5-9300H is a fast processor for laptops with four cores based on the Coffee Lake architecture [2019 Refresh, CFL-HR]. The processor clocks at between 2.4 and 4.1 GHz [4 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. Compared to the predecessor, the Core i5-8300H from 2018, the 9300H is clocked slightly higher [+100 MHz CPU, +50 MHz GPU].
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 i5-9300H should perform similar as the older Core i7-7920HQ [3.1 - 4.1 GHz]. The faster Coffee Lake CPUs, like the Core i7-8750H/9750H offers two additional cores and is therefore up to 50% faster in multithreaded benchmarks. Still, the performance of the i5-9300H 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. 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.
Intel Core i5-9400H

The Intel Core i5-9400H is a high-end processor for laptops with four cores based on the Coffee Lake architecture [2019 refresh, CFL-HR]. The processor clocks at between 2.5 and 4.3 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. Compared to the predecessor, the Core i5-8400H from 2018, the 9300H is only clocked slightly higher [+100 MHz CPU Turbo, +50 MHz GPU].

Beware, the CPU was not yet released at the time of writing and the information is based on leaks and early price list information [e.g. by Intel or on Baidu].
