Intel Core i7-10850H vs Intel Core i7-8557U
Intel Core i7-10850H
► remove from comparison
The Intel Core i7-10850H is a high-end processor for laptops with six cores based on the Comet Lake architecture (CML-H, 4th generation of Skylake). The processor clocks at between 2.7 and 5.1 GHz (with Thermal Velocity Boost and Turbo Boost 3.0). Using only Turbo Boost 3.0 (when the temperatures don't allow the the Thermal Velocity Boost) a single core can reach 4.9 GHz. All six cores can reach 4.4 GHz. The processor is still manufactured on the old 14nm (14nm++) process.
The Comet Lake architecture is similar to Coffee Lake and offers the same features and is produced on the same 14nm process. Other than the improved clock rates, the memory controller now also supports faster DDR4-2933 RAM. More information on Comet Lake and all the models and articles on it can be found here.
The Core i7-10850H supports the management features vPro, TXT and SIPP.
Performance
The average 10850H in our database proves to be a somewhat disappointing CPU, only matching the Core i5-10500H and the Ryzen 5 5500U in multi-thread performance. While the Core i7 will have no issue running any app or any game you can install in 2021, there are better options out there both in terms of sheer power and in terms of power efficiency.
Your mileage may vary depending on how high the CPU power limits are, and how competent the cooling solution of your system is.
Graphics
The integrated Intel UHD Graphics 630 iGPU is supposed to offer a similar performance as the UHD 630 in the Core i7-9750H. As a low-end solution it will only run 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 free to reduce somewhat (with 35 W being the minimum Intel-recommended value) resulting in lower clock speeds and lower performance. Either way, the CPU is way too power-hungry to be the heart of a passively cooled mini-PC, laptop, tablet.
The i7-10850H is manufactured on one of the old 14 nm Intel processes leading to subpar, as of early 2023, energy efficiency.
Intel Core i7-8557U
► remove from comparisonThe Intel Core i7-8557U is a quad-core SoC for notebooks based on the Coffee Lake architecture that was announced in the new entry level MacBook Pro 13 in mid 2019. Compared to its predecessor, the CPU is now a quad-core with Hyperthreading support for the execution of up to 8 threads simultaneously. The base frequency is only 1.7 GHz, but the Turbo goes all the way up to 4.5 GHz. It is also equipped with an Intel Iris Plus Graphics 645 GPU with 128 MB eDRAM, a dual-channel memory controller (DDR4) as well as VP9 and H.265 video decoding as well as encoding. The chip is still manufactured in a 14nm process with FinFET transistors.
Compared to slower Core i5 model with eDRAM and 15 Watts, the i5-8557U features 8 MB smart cache and the fastest clock of the Iris Plus GPU.
Architecture
Intel basically uses the same micro architecture compared to Kaby Lake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.
Performance
Clocked at up to 4.5 GHz, the Core i7-8557U should offer an excellent single thread performance. The multi core performance is greatly improved due to the two additional cores (compared to the predecessor) but may be limited by the 15 Watt TDP (especially for sustained workloads).
Graphics
The integrated Intel Iris Plus 645 Graphics is the GT3e model of the Coffee Lake GPU (Intel Gen. 9.5). It has 48 Execution Units running at 300-1150 MHz and the performance is comparable to a GeForce 930M or 940MX thanks to fast eDRAM cache. However, there aren't any significant improvements compared to the old Iris Plus 650, so modern games can often not be played smoothly or only at the lowest or medium settings, respectively.
Contrary to Skylake, Kaby 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 an improved 14nm++ process with FinFET transistors, which improves the efficiency even further. Intel specifies the TDP with 15 Watts and therefore suited for thin and light laptops.
