MagyarIntel Core i5-1135G7
The Intel Core i5-1135G7 is a quad-core SoC designed for the sleeker laptops. The Tiger Lake-UP3 processor was introduced in September 2020. It features four Willow Cove processor cores running at 2.4 GHz (base clock speed @ 28 W TDP) Boosting up to 4.2 GHz (1-core Boost). The all-core Boost frequency is 3.8 GHz. The CPU supports thread-doubling Hyper-Threading, allowing for up to 8 concurrent processing threads.
Architecture
A sizeable performance-per-MHz boost is one of the multiple improvements of Tiger Lake compared to the older Comet Lake and Ice Lake product families. A Core i5-1135G7 is compatible with dual-channel DDR4-3200 or LPDDR4x-4267 RAM, supports PCI-Express 4.0 (4 lanes) and is capable of HW-accelerating AI workloads. Thunderbolt 4, USB 4 and Wi-Fi 6 support is partially baked into the chip. The i5 CPU is manufactured on the second-gen 10 nm Intel SuperFin process that is supposed to 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. The faster Core i7-11X5 parts are notable for their larger Level 3 cache size (12 MB versus 8 MB) and higher clock speeds. The i5 gets soldered straight to the motherboard (BGA1449 socket) and is not user-replaceable.
Performance
The Boost sustainability depends a lot on the cooling system performance as well as the TDP settings. The average Core i5-1135G7 from our database is just as fast as the Core i5-10400H, Core i5-8300H, and Ryzen 7 3700U 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. The performance may not be ground-breaking, but it’s still on the nicer side. The CPU 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 it, either.
Graphics
The Iris Xe Graphics G7 iGPU is based on the Gen 12 architecture. It is somewhat faster than the older Iris Plus G7 (Ice Lake) and much faster than the UHD 620 (Comet Lake). In the case of the Core i5, the Xe GPU uses 80 of the 96 EUs clocked at 400 MHz to 1,300 MHz. The Iris 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.
Power Consumption
The 10 nm manufacturing process and low core count render the Tiger Lake-U processors relatively energy-efficient. The TGL-UP3 CPUs' default TDP value 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 the thinner, lighter laptops as well as the occasional high-end tablet. Long-term performance sustainability is likely to be an issue in passively-cooled setups.
