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.
The Intel Core i7-3520M is the fastest dual-core processor for laptops based on the Ivy Bridge architecture at the time of introduction in Q2 2012. Due to Hyperthreading, the two cores can handle up to four threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.9 GHz but can dynamically increase clock rates with Turbo Boost up to 3.4 GHz (for 2 active cores) and 3.6 GHz (for 1 active core). As its Sandy-Bridge-based predecessor Core i7-2640M, it offers a 4 MB L3-Cache.
Ivy Bridge is an enhanced die shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Other new features are integrated PCI Express 3.0 and DDR3(L)-1600 support.
The performance of the Core i7-3520M is slightly above a similarly clocked Sandy Bridge processor due to the architectural improvements. As a result, overall performance is about 5 - 10 % above the old i7-2640M (see benchmarks below).
The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1250 MHz with Turbo Boost, making it one of the fastest variants.
Just like most other Ivy Bridge dual-cores, the i7-3520M is rated at a TDP of 35 W. Therefore, even smaller laptops can use the Core i7.
