Intel Core i5-1135G7
The Intel Core i5-1135G7 is an energy-efficient quad-core SoC designed for sleek laptops and Ultrabooks. The Tiger Lake-U (UP3) processor was introduced in September 2020. It has four Willow Cove processor cores commanding 8 threads in total thanks to the Hyper-Threading support. The cores run at 2.4 GHz Boosting up to 4.2 GHz (1-core Boost) with the all-core Boost limited to 3.8 GHz.
Tiger Lake brings multiple improvements over the older Comet Lake and Ice Lake product families including a sizeable performance-per-MHz boost. The Core i5-1135G7 is compatible with dual-channel DDR4-3200 or LPDDR4x-4267 RAM, has a native PCI-Express 4.0 support (4 lanes) and hardware AI acceleration. Thunderbolt 4, USB 4 and Wi-Fi 6 support is partially integrated into the chip. The i5 CPU is manufactured on the second-gen 10 nm Intel SuperFin process that should be comparable to the 7 nm TSMC process Ryzen 4000 processors are manufactured on. Both the CPU cores and the iGPU have access to 8 MB of L3 cache. Faster Core i7 models are notable for the larger Level 3 cache size (12 MB versus 8 MB) and the higher clocks. Core i5-1135G7 gets soldered straight to the motherboard (BGA1449 socket) and is extremely hard to replace.
The cooling system performance as well as the TDP settings will have a huge impact on the Boost sustainability, directly influencing the CPU performance. The average Core i5-1135G7 from our database is just as fast as the Core i5-10400H, Core i5-8300H, and Ryzen 7 3700U processors in multi-core benchmarks. The single-core performance is a lot better though, reaching similar heights as the Ryzen 7 5600X and Core i7-8700K. This is a very decent CPU for thin and light laptops released in 2020 and 2021. It will have no difficulty coping with some light gaming and video editing on the go, and the simpler tasks such as web browsing and spreadsheet editing will pose no problem for the CPU either.
The Iris Xe Graphics G7 iGPU is based on a brand-new Gen 12 architecture. It is significantly faster than the older Iris Plus G7 (Ice Lake) and especially the UHD 620 (Comet Lake). In the case of the Core i5, the Xe GPU uses 80 of the 96 EUs with clocks in the range of 400 MHz to 1,300 MHz. The Iris Xe G7 (80 EUs) can drive up to 4 monitors in resolutions up to SUHD 4320p, and the built-in video decoder can handle the AVC, HEVC, VP9 and last but not the least AV1 video streams. The gaming performance is comparable to entry-level discrete graphics cards such as the Nvidia GeForce MX250.
The Tiger Lake-U processors are relatively energy-efficient thanks to the 10 nm manufacturing process and low core count. The default TDP of the TGL-U UP3 CPUs is in the range of 12 W to 28 W (the OEMs get to set the value according to their needs) to make the i5 a good fit for thin and light laptops and an occasional high-end tablet. Performance sustainability is likely to be an issue in passively-cooled setups.
