The Intel Core i3-8145U is a power efficient dual-core SoC for notebooks and Ultrabooks based on the Whiskey Lake generation and will probably be announced in August 2018. Compared to the similar named Kaby Lake-R processors (e.g. Core i3-8130U), the Whiskey Lake CPUs are now produced in a further improved 14nm process (14nm++) and offer higher clock speeds. The architecture and features are the same. The i3-8145U offers e.g. high Turbo clock speeds of 3.9 GHz (versus 3.4 GHz of the i3-8130U) for a single core (3.7 GHz for 2 cores) but a slightly lower base clock of 2.1 versus 2.2 GHz. The integrated GPU is still named Intel UHD Graphics 620 and the dual-channel memory controller still supports the same RAM speeds as Kaby-Lake-R (DDR4-2400 / LPDDR3-2133). Thermal Velocity Boost is not supported (only in the Core i7-8565U).
The Whiskey Lake SoCs are used with a new PCH produced in 14nm that supports USB 3.1 Gen 2 (10 Gbps) and CNVi WiFi/BT parts.
Architecture
Intel basically uses the same micro architecture compared to Skylake and Kaby Lake, so the per-MHz performance does not differ. That means Whiskey Lake is a Kaby Lake chip manufactured in the improved 14nm++ process.
Performance
Due to the higher Turbo Boost (+12% single core), the Core i3-8145U should be faster than the old Core i3-8130U (Kaby Lake-R). The single core Turbo Boost is similar to the old high end model, the Core i7-7600U. However, the guaranteed base clock of 2.1 GHz is a lot lower (2.8 GHz for the i7-7600U) and also the 2-core Turbo is lower (3.7 versus 3.8 GHz). Therefore, the performance should be similar to the Core i7-7500U (Kaby Lake).
Contrary to Skylake, Kaby Lake and Whiskey Lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors announced in January should also support HDCP 2.2.
Power Consumption
The chip is manufactured in a further improved 14nm process with FinFET transistors (14nm++), the same as the 8th Gen Coffee Lake processors. Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. Depending on the usage scenario, the TDP can vary between 7.5 (cTDP Down) and 25 Watts.

The AMD Ryzen 3 3200U is a dual-core SoC designed for laptops that was announced in January 2019. The Ryzen features two Zen cores with support for the thread-doubling SMT tech, clocked at 2.6 GHz - 3.5 GHz. The built-in Radeon RX Vega 3 iGPU has 3 CUs (192 unified shaders) clocked at up to 1,200 MHz. The default TDP is 15 W which makes the Ryzen a good fit for thin mid-range laptops.
In comparison to the faster Ryzen 3000 CPUs, the 3200U is not using the newer Zen+ microarchitecture and is still manufactured in 14nm. Compared to the old Ryzen 3 2200U, the 3200U therefore only offers a 100 MHz higher clock speed.
The Ryzen 3 is compatible with single-channel or dual-channel DDR4-2400 RAM.
The average 3200U in our extensive database is anything but a performance monster, its multi-thread benchmark scores only just matching those of the Core i3-8130U and the Pentium N6000. While not as atrociously slow as most N-series and J-series Intel chips, this specific Ryzen is good enough for basic day-to-day activities only.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Power consumption
This Ryzen 3 series chip has a default TDP, also known as the long-term power limit, of 15 W. Laptop makers are free to change that to anything between 12 W and 25 W; most will go for a higher value to extract more performance out of it. Either way, an active cooling solution will be needed to dissipate the heat.
The R3 3200U is built with a 14 nm manufacturing process for low, as of early 2023, energy efficiency.
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.
