The Intel Core i3-1115G4 is a dual-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP3) that was launched in September 2020. It integrates two Willow Cove processor cores (4 threads thanks to HyperThreading). Each core can clock from 3 GHz (base speed) to 4.1 GHz (single- and dual-core boost). The faster Core i5 and i7 models offer more cores and are therefore significantly faster.
Another novelty is the integrated Xe graphics card based on the completely new Gen 12 architecture. In the i3-1115G4 Intel is naming the GPU UHD Graphics and offers only 48 of the 96 EUs clocked at 400 - 1250 MHz. 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 WiFi 6 in the chip.
The chip is produced on the second-gen 10 nm Intel SuperFin process that should be comparable to the 7 nm TSMC process (e.g. Ryzen 4000 series).
Performance
Multi-thread peformance is most comparable to what the Intel Core i5-8250U and the AMD Ryzen 5 3450U deliver. This makes the i3 a more than decent option for day-to-day tasks; that said, any workload of the more taxing kind (such as exporting a high-bitrate, hour long UHD video) will be enough to bring the i3 to its knees.
Thanks to its decent cooling solution and a long-term CPU power limit of 25 W, the ThinkPad L15 G2-20X4S0KU00 is one of the fastest laptops powered by the 1115G4 we know of. It can be more than 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Core i3 series chip has a default TDP of 12 W to 28 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, that's a tad too high to allow for passively cooled laptops, tablets, mini-PCs.
The Core i3-1115G4 is built with Intel's third-gen 10 nm process marketed as SuperFin for decent, as of mid 2022, energy efficiency.
The Intel Core i5-8350U is a power efficient quad-core SoC for notebooks and Ultrabooks based on the Kaby Lake Refresh generation and was announced in August 2017. Contrary to its direct predecessor the Core i5-7300U, which were still dual-cores, the i7-8350U is equipped with four cores but at a lower base frequency of 1.7 GHz. The Turbo Boost can go up to 3,6 GHz and therefore also offer good short term single core speeds. The GPU is now named Intel UHD Graphics 620 but otherwise identical to the Intel HD Graphics 620. The integrated memory controller supports DDR4-2400 / LPDDR3-2133 and dual channel memory.
Architecture
Intel basically uses the same micro architecture compared to Skylake, 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
According to Intel, the new quad core models are up to 40% faster than their dual core predecessors. Due to the reduced TDP and the same 14nm+ process, the long term performance and throttling behaviour will be interesting and depending on the laptop design. Therefore, the older 35 Watt quad-core models should be faster in applications that demand longer CPU loads.
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 (14nm+), the same as the 7th Gen Kaby Lake processors. Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. Depending on the usage scenario, the TDP can vary between 7.5 (cTDP Down) and 25 Watts.
