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 Hyper-Threading support. The frequency can go from 2.4 GHz guaranteed base clock to as high as 4.2 GHz (1-core Boost frequency) while the all-core Boost is limited to 3.8 GHz.
Tiger Lake brings multiple improvements compared to the older Comet Lake and Ice Lake product families including a sizeable performance-per-MHz boost. Core i5-1135G7 is compatible with dual-channel DDR4-3200 or LPDDR4x-4267 RAM, has 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 on to the motherboard (BGA1449 socket) and is extremely hard to replace.
The performance depends a lot on the TDP settings as well as the cooling system quality. The average Core i5-1135G7 from our database is just as fast as Core i5-10400H, Core i5-8300H and Ryzen 7 3700U processors are according to multi-core benchmarks. The single-core performance is a lot better though, reaching similar heights as Ryzen 7 5600X and Core i7-8700K do. This is a very decent CPU for thin and light laptops released in 2020 and 2021. It can easily handle light gaming and video editing as well as the web browsing and spreadsheet editing.
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 Graphics 620. 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. Iris Xe G7 (80 EUs) can drive up to 4 monitors in resolutions of up to SUHD 4320p, and the built-in video decoder can handle AVC, HEVC, VP9 and last but not the least AV1 video streams. Gaming performance is comparable to entry-level discrete graphics cards such as Nvidia GeForce MX250.
Tiger Lake-U processors are relatively energy-efficient thanks to the 10 nm manufacturing process and the low core count. The operating range of the UP3 series is specified at 12 W to 28 W which makes the Core i5 a good choice for thin and light laptops and an occasional high-end tablet. Performance sustainability is likely to be an issue in passively-cooled setups.
