Intel Core i7-3687U vs Intel Core i3-1110G4

Intel Core i7-3687U

The Intel Core i7-3687U is the fastest ULV-processor for laptops based on the Ivy Bridge architecture at the time of introduction in Q1 2013. 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 2.1 GHz but can dynamically increase clock rates with Turbo Boost up to 3.1 GHz (for 2 active cores) and 3.3 GHz (for 1 active core). As its Sandy-Bridge-based predecessors, 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 i7-3687U is slightly above a similarly clocked Sandy Bridge processor due to the architectural improvements. Therefore, and because of the higher clock speed, the old Core i7-2677M is easily outperformed.

The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 350 MHz up to 1200 MHz with Turbo Boost, delivering a performance comparable with an AMD Radeon HD 6620G.

The ULV-CPUs are rated at a TDP of 17 W including graphics card and memory controller.  Therefore, the CPU is suited for small laptops and ultrabooks.

Intel Core i3-1110G4

The Intel Core i3-1110G4 is a power-efficient dual-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP4) that was launched in September 2020. It integrates two Willow Cove processor cores (4 threads thanks to HyperThreading). Each core can clock from 1.5 GHz (base speed at 7 Watt TDP setting) to 3.9 GHz (single- and dual-core boost). With 15 Watt TDP (cTDP-up) the base speed is 2.5 GHz.

Another novelty is the integrated Xe graphics card based on the completely new Gen 12 architecture. The i3 integrates the low end UHD Graphics G4 with 48 of the 96 EUs enabled and a clock speed of 400 - 1100 MHz. The GPU and CPU can together use the 6 MB of L3 cache.

Furthermore, Tiger Lake SoCs add PCIe 4 support (four lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4 / USB 4 and Wi-Fi 6 in the chip.

Performance

The average 1110G4 in our database is in the same league as the Celeron N5105, as far as multi-thread benchmark scores are concerned. This is the kind of performance that entry-level chips deliver, as of late 2023.

Your mileage may vary depending on how competent the cooling solution of your system is and how high the CPU power limits are.

Power consumption

Intel Core i3-1110G4 has a default TDP (also known as the long-term Power Limit) of 7 W to 15 W, the expectation being that laptop manufacturers will go for a higher value in exchange for higher performance. This Core i3 is built with the 3rd generation 10 nm process marketed as SuperFin making for decent, as of mid-2022, energy efficiency.
