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.
The Intel Core i7-1160G7 is a power-efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP4) that was introduced in September 2020. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). Each core can clock as a minimum base speed from 900 MHz (at 7 Watt TDP setting) up to 2.1 GHz (15 Watt). The maximum Turbo frequency is always 4.4 GHz and all cores at once can clock at up to 3.6 GHz. At the time of announcement, the i7-1160G7 is the fastest model of UP4 low power series.
Another novelty is the integrated Xe graphics card based on the completely new Gen 12 architecture. It should offer a significantly higher performance compared to the older Iris Plus G7 (Ice Lake). In the i7-1160G7 it uses 96 EUs and clocks at 400 - 1100 MHz. The GPU and CPU can together use the 12 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 1160G7 in our database is in the same league as the hexa-core Core i7-10810U, as far as multi-thread benchmark scores are concerned.
Thanks to its decent cooling solution and a long-term CPU power limit of 20 W, the ThinkBook 13x G1-20WJ001KGE is among the fastest laptops built around the 1160G7 that we know of. It can be around 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Core i7 processor has a default TDP of 7 W to 15 W, the expectation being that laptop manufacturers will go for a higher value in exchange for higher perormance. This is low enough to allow for passively cooled designs.
The CPU is built with Intel's 3rd generation 10 nm process marketed as SuperFin for decent, as of early 2023, energy efficiency.
The Intel Core i5-1130G7 is a power-efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP4) that was introduced in September 2020. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). Each core can clock from 0.8 GHz (base speed at 7 Watt TDP) to 1.8 GHz (base speed at 15 Watt TDP) all the way to 4 GHz (1 core boost for all TDPs). All cores at once can clock at up to 3.4 GHz.
Another novelty is the integrated Xe graphics card based on the completely new Gen 12 architecture. It should offer a significantly higher performance compared to the older Iris Plus G7 (Ice Lake). In the i5-1130G7 it uses 80 of the 96 EUs and clocks between 400 - 1100 MHz. The GPU and CPU can together use the 8 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 1130G7 in our database is very close to the N95 and also the Core i5-1140G7, as far as multi-thread benchmark scores are concerned. This is a so-so result, as of early 2023.
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 Core i5 has a default TDP of 7 W to 15 W, the expectation being that laptop manufacturers will go for a higher value in exchange for higher performance. These values are fairly low, meaning at least a few passively cooled designs are to be expected.
The CPU is built with Intel's 3rd generation 10 nm process marketed as SuperFin for decent, as of late 2022, energy efficiency.
