Intel Core i7-3612QM vs Intel Core i5-10200H

Intel Core i7-3612QM

The Intel Core i7-3612QM is a fast quad-core processor for laptops based on the Ivy Bridge architecture. It is the fastest mobile processor rated at 35 Watt (at the time of announcement in mid 2012). Due to Hyperthreading, the four cores can handle up to eight threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.1 GHz but can dynamically increase clock rates with Turbo Boost up to 2.8 GHz (for 4 active cores), 3.0 GHz (for 2 active cores) and 3.1 GHz (for 1 active core). Compared to the other quad core CPU, the 3612QM is specified at a TDP of only 35 Watt (similar to the dual-core CPUs). The BGA version (that is directly soldered to the mainboard) supports VT-d virtualization, whereas the rPGA version does not. Both dont support vPro, but otherwise all Ivy Bridge features like AES or VT-x are useable.

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 i7-3612QM is slightly above a similarly clocked Sandy Bridge processor due to the architectural improvements. As a result, overall performance is similar to the Sandy Bridge Core i7-2820QM. Altough the 3612QM has a higher model number than the 3610QM, it offers slower clock rates and therefore performs worse. However, the 3610QM is specified at a much higher TDP of 45 Watt.

The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1100 MHz with Turbo Boost, making it one of the faster variants.

With a TDP of only 35 Watt, the Core i7-3612QM is the first quad-core CPU from Intel that is specified at the level of the dual-core mobile CPUs. Therefore, even smaller laptops can use the Core i7.

Intel Core i5-10200H

The Intel Core i5-10200H is a fast quad-core processor for laptops with four cores based on the Comet Lake-H series (4th generation of Skylake architecture). The processor clocks at between 2.4 and 4.1 GHz  and can execute up to eight threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured on 14nm (14nm++) process.

The Comet Lake architecture is similar to Coffee Lake and offers the same features and is produced in 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 i5-10200H supports no vPro, TXT or SIPP. These business features are available in the faster (and later released) Core i5-10400H (2.6 - 4.6 GHz).

Performance

The performance is only minimal better than the Core i5-9300H thanks to the support for faster DDR4-2933 RAM. This means, the CPU is well suited for demanding tasks, although the faster versions offer a significantly higher Turbo Boost clock speed for faster single core execution. 

Power consumption

This 10th gen Comet Lake processor has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop manufacturers are allowed to reduce somewhat, 35 W being the lower limit. Doing so will result in lower clock speeds and lower performance. Either way, this CPU is too power-hungry to be used as the base of a passively cooled laptop.

Intel Core i5-10200H is built with an old, as of late 2022, 14 nm Intel process for subpar energy efficiency.
